ASME SA573 is a Standard Specification for Structural Carbon Steel Plates of Improved Toughness under the jurisdiction of ASTM Committee A01 on Steel, Stainless Steel and Related Alloys and is the direct responsibility of Subcommittee A01.02 on Structural Steel for Bridges, Buildings, Rolling Stock and Ships. Katalor often offer the
plates of A573 grade 70 and the M.O.Q. of each size can be 6MT.

A537 Grade 70 plates furnished shall conform to the requirements of the current edition of Specification A6/A6M, unless a conflict exists in which case this specification shall prevail. The A537 Gr. 70 product analysis shall conform to the requirements given in Table 1 subject to the product analysis tolerances in Specification A6/A6M. For each reduction of 0.01% point below the specified maximum for carbon, an increase of 0.06% points above the specified maximum for manganese(0.85~1.2%) is permitted up to a maximum of 1.60 % for SA537 Grade 70. Elongation need not be determined for floor plate SA537 Gr.70. For A537 Grade 70 plates wider than 24 in. [600 mm], the elongation requirement is reduced 2% points. See the Elongation Requirement Adjustments subsection in the Tension Tests section of Specification A6/A6M.
