Standard Specification for Tin Mill Products, General Requirements

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 any conflict in requirements, the requirements of the purchase order, the individual material specification, and this general specification shall prevail in the sequence named.

Note 1: A complete metric companion to Specification A623 has been developed—Specification A623M; therefore no metric equivalents are presented in this specification.

1.3 The following safety caveat covers Annex A3 through Annex A10 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
