Weldability of a573 grade 65 [450] high strength carbon steel

SA387Gr5Cl2 steel material is suitable for refining and gas treatment in hydrogenation and conversion equipment at high temperature. The maximum thickness of a573 grade 65 [450] high strength carbon steel, SA387Gr5Cl2 steel plate can reach 250mm. According to different thickness and impact requirements, the heat treatment of SA387Gr5Cl2 steel plate is normalizing plus tempering or normalizing plus rapid cooling plus tempering. By using special smelting method, the content of phosphorus is reduced so that sa387 has high brittleness resistance and good impact toughness at low temperature.

Grade Q420 steel has high strength, especially in the normalizing or normalizing and tempering state. a573 grade 65 [450] high strength carbon steel, Q420 steel has high comprehensive mechanical properties. Q420 steel is mainly used for large ships, bridges, power station equipment, medium and high pressure boilers, high pressure vessels, rolling stock, hoisting machinery, mining machinery and other large welded structural parts. Grade Q460 steel, with high strength, has high comprehensive mechanical properties in normalizing, normalizing and tempering or quenching and tempering states. The quality grades are C, D, E. Q460 steel is used in various large engineering structures and light structures requiring high strength and heavy load.
