SA516Gr70 steelmaking process: the steel should be killed steel and meet the requirements of A20 / A20M standard fine austenite grain size. Related steel grades are: SA515GR60, SA515GR70, SA516GR60, SA516GR70, SA516GR60N, SA516GR70N, P265GH plate.Chemical composition analysis of SA516Gr70: C: no more than 0.3, Mn: 0.79-1.30, P: no more than 0.035, S: no more than 0.035, Si: 0.13-0.45.

The purpose of p265gh plate quenching is to transform the supercooled austenite into martensite or bainite to obtain a martensite or bainite structure, and then cooperate with tempering at different temperatures to greatly improve the strength, hardness, performance, fatigue strength, toughness, and wear resistance etc. of p265gh plate. So as to meet the different use requirements of various mechanical parts and tools. Quenching can also help to get the ferromagnetic, corrosion resistance and other special physical and chemical properties of certain special steels.

South Korean p265gh plate steel industry said that the slowdown in economic growth superimposed on the impact of the epidemic, steel demand weakened, exports were sluggish, enterprises are facing huge operating pressure. Due to the delay in the resumption of work of Chinese p265gh plate steel enterprises, the steel inventory is growing rapidly. According to statistics, China's steel circulation inventory reached 23.75 million tons in February, the highest since 2006, with an estimated total inventory of 33.45 million tons.

The main uses of flat steel are as follows. First, flat steel is used as a raw material for processing steel plates, which is convenient for transportation, takes up a small space, and can save transportation costs. Second, p265gh plate flat steel can be used as raw material for processing welded pipes. Flat steel can be a finished steel product, or it can be used as a billet for welded pipes and thin slabs for stacked sheets. Third, flat steel can be directly used as a steel structure. As a finished material, flat steel can be used for making hoop iron, tools and mechanical parts, and used as building frame structure and escalator in construction. Fourth, the flat steel has a smooth surface and a certain degree of beauty.
