Pressure Vessel Steel Plate – High-Pressure & Elevated Temperature Solutions

OurPressure Vessel Steel Platesare high-quality carbon and alloy steels specifically designed for the fabrication of airtight tanks, boilers, and heat exchangers. These plates are engineered to maintain structural integrity under intense internal pressure and varying temperature ranges. With low sulfur and phosphorus content and specialized heat treatments, our plates offer the notch toughness and weldability required for the world's most demanding industrial environments.

Common Standards and Steel Grades

We provide a comprehensive range of boiler-quality plates that comply with international safety standards:

ASTM A516 / ASME SA516:The most popular choice for moderate and lower-temperature service.

Common Grades:Grade 60, Grade 65, Grade 70(Most common for high-tensile requirements).

ASTM A537 / ASME SA537:Heat-treated, carbon-manganese-silicon steel for pressurized tanks and structures.

Classes:Class 1 (Normalized), Class 2 (Quenched & Tempered).

ASTM A387 / ASME SA387 (Chrome-Moly):Alloy steel plates for high-temperature service.

Common Grades:Grade 5, Grade 11, Grade 12, Grade 22, Grade 91.

ASTM A285:Low and intermediate tensile strength carbon steel plates for fusion-welded pressure vessels.

EN 10028-2/3:European standard for pressure purposes (P265GH, P355NH, P355NL1).
