SA516 grade 55, SA516 grade 60, SA516 grade 65, SA516 grade 70. These four grades p235gh steel equivalent are mainly defined by different tensile and yield strength ranges, which are affected by carbon content.

Grade Q420 steel has high strength, especially in the normalizing or normalizing and tempering state. p235gh steel equivalent, 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.

After twenty years of efforts, the company has completed the steel plates production process and complete testing equipment from smelting, rolling, drawing, heat treatment to p235gh steel equivalent full material. Large-scale production, intensive, and unremitting research and development and innovation make our products maintain long-term vitality. In early 2008, the company established the Ministry of foreign trade, and our p235gh steel equivalent steel plate products are now exported to the South Asia, the Middle East, Europe and the United States.
