High-Temperature Certified Plates for Steam Generation & Heat Recovery
Boiler plates are specifically qualified for the fabrication of fired and unfired steam drums, boilers, and high-temperature pressure equipment. They are certified for elevated temperature tensile properties and are often subject to additional testing beyond standard PVQ plates.
Available Standards & Grades
Standard Grades Key Application
ASTM A515 Grade 60, 65, 70 Boiler drums and shells (intermediate to high temperature)
ASTM A516 Grade 60, 65, 70 Boilers requiring moderate/low-temperature notch toughness
ASTM A204 Grade A, B, C (C-0.5Mo) Elevated temperature boilers, waste heat recovery
ASTM A299 Grade A, B (Mn-Si) High-temperature boilers and pressure vessels
ASTM A302 Grade A, B, C, D (Mn-Mo, Mn-Mo-Ni) High-strength boiler applications
EN 10028-2 P235GH, P265GH, P295GH, P355GH European standard boiler and pressure vessel plates
