ASTM A285 standard is for carbon steel, low and intermediate tensile strength steel plates intended for fusion-welded pressure vessels. The steel plate under ASTM A285 ranges in three grades, A, B and C, most common use is ASTM A285 Grade C plates.

ASTM A387 steel plate is chromium-molybdenum steel for pressure vessels for elevated temperature service. ASTM A387 steel plate include ASTM A387 Grade 5, Grade 9, Grade 11, Grade 12, Grade 22. Each A387 grade is divided into 2 class: class 1 and class 2.

ASTM A514 steel (also known as T1) grades incloud A, B, E, F, H, P, Q & S. This steel plate has a high yield strength and good weldability. ASTM A514 steel plate is quenched and tempered carbon-alloy steel. It is typically used when abrasion resistance and high-impact properties are required.

ASTM A515 carbon-silicon steel plates primarily for intermediate- and higher-temperature service in welded boilers and other pressure vessels. Plates are available in three grades having different strength levels: Grades 60, 65, 70, 415, 450, and 485.

ASTM A516 covers carbon steel plates intended primarily for service in welded pressure vessels where improved notch toughness is important. According to different strength levels, the plates are available in four grades: Grades 55, 60, 65, and 70. The most common is Grade 70 or called out A516-70.

ASTM A537 standard refers to pressure vessel plates, material in heat-treated, carbon-manganese silicon steel. Based on different strength and heat treatment, it ranges to Class 1, 2 and 3. ASTM A537 Class 1 plates are supplied in the normalised condition whilst Class 2 plates are quenched and tempered.

ASTM A572 steel plate is a popular grade of high-strength low-alloy (HSLA) steel that is typically used in structural applications. A572 steel contains chemical alloys that enhance the material’s hardness and ability to bear weight. There are five different grades of A572 steel plate: Grade 42, Grade 50, Grade 55, Grade 60 and Grade 65.

ASTM A573/A573M grades are divided into: 58, 65, 70, and the steel plates are suitable for structural grade carbon-manganese-silicon steel plates in three tensile strength ranges. ASTM A573/A573M steel plates are mainly used for important purposes of improving notch toughness at room temperature.
