Carbon Steel Boiler Plate (ASTM A516 / ASME SA516 Grade 70)
Industrial Material
Why Choose A516 Gr.70 Boiler Plate Over Standard Carbon Steel?
Manufacturing pressure vessels and boilers requires uncompromising safety standards. Utilizing standard carbon steel (like SS400 or A36) under high pressure and temperature variations can lead to catastrophic failures. ASTM A516 Grade 70 Boiler Plates are specifically alloyed and heat-treated to provide superior notch toughness and high tensile strength, ensuring absolute safety and compliance with international pressure vessel codes.
Quality Assurance & Traceability (MTC)
Every boiler plate we supply is imported from world-class steel mills and comes with an original Mill Test Certificate (MTC). The heat numbers on the certificates match the physical plates, ensuring 100% traceability for your engineers and third-party inspectors.
