ASTM A515 is the same as ASME SA-515 and is the standard specification for welding carbon steel pressure vessel plates for high temperature service in boilers and other pressure vessels. 

ASTM A387 Boiler vessel plates are chrome-molybdenum alloy steel plates suitable for welding boilers and high temperature pressure vessels.

ASTM A285 Boiler Plate is a common carbon steel used for fusion welding of pressure vessel equipment such as boilers, storage tanks, heat exchangers, etc..

ASTM A204 boiler vessel plate is molybdenum alloy steel plate, mainly suitable for welding boilers and high temperature pressure vessels.

A203 pressure vessel steel plate adopts nickel alloy steel material in the manufacture of high temperature pressure vessels. The performance of ASTM A203 boiler vessel plates is based on their Ni composition.

ASTM A202 grade is divided into: A, B, boiler vessel plate is mainly used for welding boilers and other pressure vessels. There are two grades of ASTM A202 boiler vessel steel: Grade A and Grade B. The thickness of ASTM A202 boiler vessel plates is limited to 2 inches.

JIS G3101 SS400 is a common carbon structural steel grade. Other grades of JIS G3101 are ss330, ss490 and ss540. Related product types include steel plate, steel plate, steel section, steel pipe, etc.

DIN 17100 ST37 is a carbon structural steel widely used in construction, machinery and manufacturing industries. It has good mechanical properties and can be used to manufacture various mechanical parts.

EN10025-2 steel plate is a low-alloy high-strength structural steel, which is made of carbon structural steel by adding a small amount of alloying elements.
