ASME SA572 Grade 42 steel

ASTM A572M “Standard Specification for High-Strength Low-Alloy Columbium-Vanadium Structural Steel” 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 42 plates.

SA572Grade 42 is one of grade in standard ASTM SA572, in which the max thickness(or sizes) are listed. For the plates and bars of SA572Grade 42, the biggest size is 6in(150mm), while the structural shape flange of leg thickness, sheet pilings, zees and roiled tees of A572Gr. 42, the biggest size is all without limitation.

In addition, SA572 Grade 42 are the yield point levels most closely approximating a geometric progression pattern between 36ksi [250 MPa], min, yield point steels covered by Specification ASTM A36/A36M and 100 ksi [690 MPa], min, yield strength steels covered by Specification ASTM A514/A514M.

For structural products of A572 Grade 42 produced from coil and furnished without heat treatment or with stress relieving only, the additional requirements, including additional testing requirements and the reporting of additional tests, of Specification A6/A6M apply.
