SA387 Grade 11 Class 1 Alloy Boiler Plate

 

‌SA387 Grade 11 Class 1 (SA387Gr11CL1 for short) alloy boiler plate is a low alloy heat-resistant steel with good high temperature strength, oxidation resistance and corrosion resistance, mainly used for the manufacture of pressure vessels‌.

 

SA387Gr11CL1 boiler steel plate can maintain high yield strength and tensile strength at high temperatures, which can ensure structural integrity and safety under high temperature working conditions‌. SA387Gr11CL1 pressure vessel steel plate not only has high strength, but also has good impact toughness and fracture toughness as well as good welding performance. It can be connected and repaired by various welding methods, which is convenient for the manufacture and maintenance of equipment‌.
