Carbon and low alloy A588 Grade A tensile strength ksi with high strength

The metal structure of 15CrMo steel is martensite. This material has good oxidation resistance at about 650℃, good thermal strength below 600 ℃, and good shock absorption and thermal conductivity. A588 Grade A tensile strength ksi, 15CrMo steel is widely used in steam turbines. However, this type of steel has a greater tendency to harden and has poor welding performance. GB/T 3077-2015 15CrMo plates are supplied with 5 to 70MM thick, can be set to roll futures.

The A588 Grade A tensile strength ksi plate products have passed the EU CE certification, and have been recognized by China, France, the United States, the United Kingdom, Germany, Italy, Japan, South Korea and other eight classification societies for high-strength ship plates. The steel strand products have passed the United States (PTI) certification. The A588 Grade A tensile strength ksi products enjoy a high reputation in the domestic and foreign markets. The products are applied to national key projects and sold to 37 countries and regions such as EU, Middle East, Southeast Asia and America.

The hot rolling method is to heat the A588 Grade A tensile strength ksi steel material to about 1000 ℃ ~ 1250 ℃ and use the rolling mill to roll it. The traditional hot rolling process is generally divided into the following two steps: the first step is to use the primary rolling mill or billet rolling mill to roll the ingot, billet or continuous casting billet into a certain shape and size of billet. This kind of A588 Grade A tensile strength ksi rolling process is usually called semi-finished product production, also called blank production.

Mg element can reduce the number, size, distribution and morphology of inclusions in steel such as A588 Grade A tensile strength ksi. Micro Mg can improve the size and distribution of carbides in bearing steel. And the carbide particles of bearing steel containing magnesium are fine and uniform. When Mg content is 0.002% - 0.003%, the tensile strength and yield strength of the steel increase by more than 5%, and the plasticity remains basically unchanged.

The company attaches great importance to the cultivation of team spirit. Personal strength is weak. After sales service departments, leaders and subordinates often communicate with each other. Everyone often holds meetings to discuss their problems in after-sales service, discuss technical difficulties, discuss how to improve work efficiency, how to better deal with user complaints, etc.
