ASTM A285M “Standard Specification for Pressure Vessel Plates, Carbon Steel, Low- and Intermediate-Tensile Strength” is under the jurisdiction of ASTM Committee A01 on Steel, Stainless Steel and Related Alloys and is the direct responsibility of Subcommittee A01.11 on Steel Plates for Boilers and Pressure Vessels. There are three grade in the standard ASTM A285M--Grade A, B, C etc. Katalor always keeps thousands of steel pressure vessel plates including A285 plates.

In standard of ASTM A285M, there is a grade ASTM A285GR. B which is a kind of carbon steel plates of low-and intermediate-tensile strengths which may be killed or semi-killed at the producer’s option.
The material of ASTM A285 Grade B supplied to this specification shall conform to Specification A20/A20M. These requirements out-line the testing and retesting methods and procedures, permitted variations in dimensions, and mass, quality and repair of defects, marking, loading, and ordering information.
The plate of ASTM A285 Grade B can make Ultrasonic Examination in accordance with Standard ASTM A435M, ASTM A577M & ASTM A578M etc.
