GENERAL POLICIES
Claims Policy
Overview
If material appears to be defective, the customer shall
attempt to process the material as usual. If the material
appears to have numerous imperfections or defects after a minimum of 10% has been processed, the customer
may then suspend production and notify AHMSA, and a
technical service representative will arrange to inspect the
material.
The customer shall notify AHMSA of any technical or administrative claims via www.ahmsa.com or customer service representative. Once a claim has been initiated, the
Sales and Technical Service departments will be notified
in order to seek resolution.
Oxidation Claims
AHMSA shall not be held responsible for certain claims
arising from the oxidation of our products. Discoloration
and staining is inherent from the presence of atmospheric
humidity and the collection of condensation in transit. Because of the reactivity of steel, oxidation may be present
between the layers in coils or between bundled sheets.
AHMSA shall not be held responsible for the following oxidation claims:
1. When material is ordered without oil (dry) or without a
suitable surface treatment.
2. When orders specify packaging with less than AHMSA’s
approved minimum level of protection.
3. When the steel is stored outdoors, or if left unprotected
against moisture or sudden temperature changes.
Note: If upon delivery the steel coil temperature is below
the warehouse temperature, the customer shall not unpack
the material until the coil temperature equalizes with the
warehouse.
Weight Variation
Claims
A variation up to + /- 1% of the scale weight per invoiced
shipment shall be allowed between the customer and
AHMSA, before a claim may be initiated.
Will be considered in the following cases:
1. Upon delivery, all items have immediately been inspected for the presence of moisture in the package.
2. If moisture in the packaging is present at the time of
delivery, an annotation must be made in the delivery
log while in the presence of the carrier. AHMSA sales
must then be notified immediately.
3. Before the material is delivered to the customer or the
customer’s contracted carrier.
For material that is picked up by the customer, the claim
must be made to the customer’s contracted carrier. AHMSA
sales must then be notified immediately.
Wet in Transit
Claims
4
Full Hard Steel,
Direct from the Mill
Unless otherwise specified, full hard steel is directly shipped
from the reduction mill. The variation in head and tail ends
thicknesses shall not constitute grounds for a claim.
Mechanical
Properties and
Chemical Analysis
Data referring to mechanical properties or chemical analysis are the result of tests performed on samples obtained
from specific locations of the product(s), in accordance with
the prescribed sampling procedures. Any warranty thereof
is limited to the values obtained at such locations and by
such procedures.
Permissible
Variations
Products sold by AHMSA shall be subject to the variations,
tolerances, and classifications defined by international steel
manufacturing standards as referenced in this manual.
The number of significant digits applied to testing are in
accordance with ASTM E-29.
AHMSA is not responsible for the outcomes of any technical
recommendation associated with the design, installation
and use of AHMSA’s products in this publication.

steel manufacturing standards. The hot-rolling process
results in a product with defects such as mechanical scratches, marks, scale and surface oxidation.
Hot rolled coils are supplied with the Head and Tail ends
out off gauge. Neither the variation in head and tail ends
thicknesses or coiler marks shall constitute grounds for
a claim.

Depending on the chemical composition of the steel, Hot Rolled Plate (HRO) is available
with mill edge or cut edge, in a 0.312” to 2.000” thickness, and a width of 56” to 120”.
AHMSA does not guarantee internal quality for steel plate thicker than 2”.
The surface finish of hot rolled plate is semi-smooth and may have oxidation. Hot rolled
plate is used for structural applications or where the surface quality is not critical.
The typical applications of AHMSA steel plate are listed in tables 1, 2, 3, and 4 of this
section.

1 A production feasibility study is always required for these steel grades.
Note: The weight of each coil must be between 6 to 20 metric tons depending of grade and dimensions.
31
Hot rolled steel coils that are not pickled (dry) are manufactured with a mill edge in
thicknesses from 0.059” to 0.500” and widths from 29” to 63.750”. Specific grade sizes
can be referenced in size tables 1 through 5 of this section.
The surface finishes of hot rolled coils are semi-smooth and may have oxidation.
Hot rolled coils are used for structural applications or where the surface quality is not
critical. The typical applications of AHMSA steel coils include heavy machinery wear
parts, crossties, pipes, and tubes.
When the application requires a quality surface finish or painting, such as in the
automotive industry, pickling or another cleaning process should be performed by the
customer, or the customer should consider purchasing AHMSA’s pickled steel coils.

STEEL FOR MOTOR LAMINATION AND BALLAST, SEMI-PROCESSED
(NON-ORIENTED GRAIN)
The magnetic field cores of electrical equipment consist of pilings of steel sheets
stamped to size and shape necessaries form a core. For maximum electrical efficiency,
cores must be made of material having good magnetic properties, in particular, high
permeability and low core loss.
Permeability: Is the relative ease in which material becomes magnetized. For steels
produced in AHMSA, guarantee is of 2,000 Gauss/Oersted minimum.
Semi processed (non-oriented grain) electrical steels: This material does not have fully
developed magnetic characteristics, it requires of an annealing process done by the
costumer, usually after the stamping to develop the desired magnetic properties. This
steel can be supplied in a range of physical and mechanical characteristics and can be
matched to specific customer stamping and annealing practices.

subject the coil to sudden temperature changes.
Unpack after the coil is at room temperature to prevent condensation and subsequent oxidation problem.
Claims will not proceed if:
The tested chromium levels in the surface of the client’s samples indicate normal passivation (0.35 mg/ft 2 minimum).
The relative humidity of the warehouse is high (> 75%).
The original packing is removed or damaged (applicable to the
rejection of batches of coils).
The cut to length sheets from the coil are not stored with proper
packaging for a period exceeding one month. These conditions
will cause discoloration by tin oxidization.
Tin Plate coil production in continuous mill lines does not allow
for the removal of non-compliant sheets, therefore, during cutting,
the non compliant sheets shall be separated from the cutting line
for evaluation.
According to the Tables 18 and 19.
Roughness range specified in Tin Plate corresponds to the base
steel surface finish; in finished product it can vary, depending on
the coating layer (ASTM A-624, section 5.2).
Note:
·Discount subjected to the coil status and other parameters.
·Claims will be accepted no later than 6 months after shipment.

GLOSSARY
It would take a whole book to define all the terms used in connection with the
manufacture, sale, and use of steel products. However, the following definitions
are limited to the more common terms which can be useful for our customers and
sales people alike. We recommend that you consult a book titled, “The Making,
Shaping, and Treating of Steel” if you are interested in collecting more technical
knowledge beyond what we have defined.
AGING
Changes in physical and mechanical properties that occur when low carbon
steel is stored for a period of time. Aging is also accelerated by exposure of
steel to elevated temperatures. Stretcher strains and fluting can result from
aging.
ANNEALING
A process of applying heating and cooling to Hot Rolled and Cold Rolled Sheet
products to induce softening.
BASE BoX
An area unit equivalent to 112 sheets 14 x 20 in.
BASE WEIGHT
Nominal weight in pounds per base box is an approximate thickness measurement. The Tin Plate ordered for its thickness equals the unit weight per base
box.
BUNDLE
Consists of ten packages which are 1,120 sheets/packages.
CAMBER
Camber is the deviation of a side edge from a straight line. It is the measurement
being taken on the concave side with a straight edge.
CaRBON STEeL
CCT
Full Hard steel with tension leveling process.
CTT
Cold roll steel (tempered), with tension leveling process.
COIL BREAKS
Creases or ridges which appear as parallel lines, transverse to the direction of
rolling. They generally extend the width of the sheet.
78
GLOSSARY A-C
Steel which owes its properties primarily to carbon without substantial amount of
other alloying elements: Steel is classified as carbon steel when the maximum
content does not exceed the following percentages: Carbon 0.50%, Manganese
1.65%, Silicon 0.30% and Copper 0.20% (when specified).
COLD ROLLED PRODUCT
Flat rolled products for which the required thickness has been obtained by
rolling without heating at room temperature.
COMMERCIAL QUALITY STEEL (CQ oR CS)
Steel of this quality is for uses involving simple bending or moderate drawing.
Commercial quality sheet can be bent flat upon itself in any direction at room
temperature.
CORROSION
Gradual chemical or electrochemical attack on metal by atmospheric moisture
or other agents.
CUTTED EDGE
Side cutting on the pickled and hot rolled process.
DEEP DrAWING QUALITY STEEL (DDS)
DDS is manufactured when Drawing Quality (DS) won´t provide a sufficient
degree of ductility for fabrication of parts. Deep Drawing Quality requires that
the sheet be free from aging and uses special killed steel. This quality is made
by special steelmaking and processing practices.
DRaFT
Reducing thickness of strip by hot or cold rolling.
DrAWING QUALITY STEEL (DS)
As compared to Commercial Quality steel, Drawing Quality steel has a greater
degree of ductility and is more consistent in performance. This greater ductility
and uniformity are a result of higher production standards, selection and processing of the steel.
ELECTROLYTIC CLEANING L INE
Electrolytic cleaning process for cold rolled steel.
FULL HARD
Cold reduced sheet that has not been annealed.
FULL HARD FULL HARD
Cold reduced sheet that has not been annealed, where stiffness is required.
HOR
Hot roll coil, mill edge.
HOT ROLLED
This term describes flat steel products that are produced to finished size by
rolling at high temperatures.
HOT ROLLED CUT TO LENGTH SHEET (ORH)
Cut to length sheets from Hot rolled, mill edge coils, available in light and heavy
thicknesses.
79
GLOSSARY C-H
HAR
Floor plate in coil.
HRO
Wide Plate Steel.
HRP
Hot rolled pickled and oil or without oil.
KillED STEEL
Steel deoxidized by silicon or aluminum to reduce the oxygen content to a
minimum so that no reaction occurs during solidification of the metal.
LaminaTIONS
Imperfections resulting from the presence of blisters, seams or foreign inclusions. These are sometimes visible on the surface of the metal.
LUBRICITY
Otherwise known as slipperiness, it is the ability of steel sheet to slide on forming
dies.
Mill EDGE (OM)
Normal rounded edge produced in hot rolling of flat steel.
OilED
Application of a suitable rust inhibitive oil applied to flat rolled steel in the effort
to retard rusting. When surface finish is important, the oil helps to reduce friction
scratches that may develop in transit. The oil coating is not intended to serve
as a lubricant for subsequent fabrication.
PaCKAGES
A unit quantity of 112 sheets for Tin Plate product.
PICKLING
Removal of mill scale or oxidation by immersion of steel into a dilute solution
bath of hydrochloric acid. The steel is then rinsed, dried, and is oiled (as requested).
PITTING
Is a form of extremely localized corrosion that leads to the creation of small
cavities in the metal.
QUALITY
Refers to accuracy of the steel for the purpose or purposes for which it is intended (See Commercial Quality, Drawing Quality, and Structural Quality).
ROUGHNESS
Surface finish or Surface texture of the steel which form on the surface of hot
steel.
80
GLOSSARY H-R
PROFILOMETER
An instrument that measures surface-roughness height in micro-inches. The
height is measured as the absolute deviation from a mean surface.
ScaLE
Typically called Mill scale, is defined as a surface layer of primarily ferric oxide
that forms on the exterior of steel or iron when hot.
SlaB
A semi-finished steel block having an oblong cross-section in which the width is
at least twice its thickness. It differs from a bloom which has a square or nearly
square cross-section.
STiffness
The physical property of being inflexible and hard to bend.
STrUCTURAL QUALITY
When other values of mechanical properties are specified, tests are required
to verify the mechanical specifications such as tensile strength, yield point, and
elongation.
TENSION LEVELING
The process to improve flatness, the strip is under great tension with a slight
elongation above the yield point of the material, and simultaneously leveled.
The material is shape corrected and relieved of most internal stresses.
TeMPERING
A series of heat treatments to “toughen the metal”. In doing so, the temper
process provides a matte or bright surface finish and improves the flatness of
the steel.
TCO
Tin Plate in coil.
TFS
Tin Free Steel. (Electrolytic chromium plate).
THEORETICAL WEIGHT
A calculated weight based on nominal dimensions and steel density of 0.129
kg/in 3 (7.85 gr/cm 3 ) for plate, coil and sheet products.
TOLERANCE
Specified limits of deviation from a dimension.
TRIMMED EDGE (TIN PLATE OR TIN FREE STEEL)
Side trimming on the Plating process (Tin Plate or Tin Free Steel).
