ASTM A572M is 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. There are six grade in the standard ASTM A572M--Grade 42, Grade 50, Grade 55, Grade 60 and Grade 65etc. Katalor always keeps thousands of high-strength low-alloy plates including
SA572 Grade 65 plates.

SA572 Gr. 65 are intended for riveted or bolted construction of bridges, or for riveted, bolted, or welded construction in other applications. And the max sizes of A572 Grade 65 plates and bars is 1-1/4in(32mm), while the max sizes of SA572Gr.65 structural shape flanges or leg thickness is 2in(50mm).
For the chemical composition of A572Gr.65 in thickness ≤25mm, Carbon content is max. 0.26% and Manganese content is max. 1.35%, while each reduction of 0.01 percentage point below the specified carbon maximum, an increase of 0.06 percentage point manganese above the specified maximum is permitted, up to a maximum of 1.60 %.
For applications of SA572Gr.65, such as welded bridge construction,where notch toughness is important, notch toughness requirements are to be negotiated between the purchaser and the producer.
