ASTM A533 Boiler vessel plates are manganese-molybdenum and manganese-molybdenum-nickel alloy steel plates suitable for welding pressure vessels. Often with quenching and tempering heat treatment, that is, quenching and tempering state supply. ASTM A533 boiler vessel steel is available in five different strength grades: Grade A, Grade B, Grade C, Grade D. There are three levels of each category: level 1, level 2 and level 3.
A533 Grade A Adopt standard: ASMT A533/A533M Standard Specification for pressure Vessel Plates,Alloy Steel,Quenched and tempered,Manganese-Molybdenum and Manganese-Molybdenum-Nickel
A533 Grade A Specification: Thickness: 5mm to 200mm; Width: 1500mm to 3500mm: Length: 3000mm to 27000mm
Third Party Inspection for A533 TYPE A: ABS, DNV, BV, GL, CCS, LR, RINA, KR, NK, CE, SGS, IKE, IEI or other quality department.
