ASTM A623M-10

Standard Specification for Tin Mill Products, General Requirements [Metric]

ABSTRACT
This specification covers a group of common requirements which shall apply to tin mill products. The steel shall be made by the open-hearth, electric-furnace, or basic-oxygen process. The steel shall conform to specified chemical composition requirements. Rockwell 30T hardness test shall be done to the plates. This test forms the basis for a system of temper designation. The mechanical properties of continuously annealed plate and batch annealed plate of the same Rockwell 30T temper designation are not identical. It is important to keep in mind, that the Rockwell 30T test does not measure all various factors which contribute to the fabrication characteristics of the plate.
SCOPE
1.1 This specification covers a group of common requirements which, unless otherwise specified in the purchase order or in an individual specification, shall apply to tin mill products.
1.2 In case of conflict in requirements, the requirements of the purchase order, the individual material specification,and this general specification shall prevail in the sequence named.
1.3 The following safety hazards caveat covers Annex A1 through Annex A8 of this specification: This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
Note 1—A complete inch-pound companion to Specification A623M has been developedA623; therefore, no inch-pound equivalents are presented.

Users of the standard should note several very significant differences in how the product is produced
and marketed.
(1) The metric product does not carry the overrun associated with tin mill products produced to
customary units. Metric tin mill products are produced to ordered size.

(2)Themetricproductisdesignatedinunitsof100m calledaSITA(SystemInternationalTinplate

(3) The metric product is designated by thickness in millimetres rather than by basis weight.
(4) Coating weights are given in grams per square metre, not pounds per base box.
(5) Thickness tolerances are given in absolute figures instead of a 6 percentage.
(6) Each package of metric tin mill products contains 100 sheets, not the 112 of customary unit
packages.
