A516 Gr65 Steel Vs S500MC tensile strength

After 1975, our equipment includes blast furnaces, electric furnaces, vacuum refining furnaces, and electroslag furnaces. The product varieties are relatively complete. Plates, S500MC tensile strength tubes, wires, belts, and profiles have a certain scale

After 1975, our equipment includes blast furnaces, electric furnaces, vacuum refining furnaces, and electroslag furnaces. The product varieties are relatively complete. Plates, S500MC tensile strength tubes, wires, belts, and profiles have a certain scale, including magnetic, elastic, expanded, bimetal and other precision alloy materials for national defense and electronics industries. In 1982, these plants produced 364,000 tons of S500MC tensile strength steel and 542,000 tons of steel.

Hydrogen (H) is the most harmful element in general steel such as S500MC tensile strength. Hydrogen dissolved in steel will cause hydrogen embrittlement, white spots and other defects. Hydrogen, like oxygen and nitrogen, has very little solubility in solid steel. It dissolves into liquid steel at high temperature, and accumulates in the structure without time to escape when cooling, forming high-pressure micro pores, which greatly reduce the plasticity, toughness and fatigue strength of steel, and even cause cracks and brittle fracture in severe cases. "Hydrogen embrittlement" mainly occurs in martensitic steel, but not very prominent in ferrite steel, and generally increases with hardness and carbon content.

S355J2G3 is low alloy high strength structural steel, and it is roughly equivalent to GB Q345D.S355J2G3 is a European standard steel with composition of C ≤ 0.20, Si ≤ 0.55, Mn ≤ 1.60, P ≤ 0.035, S ≤ 0.035. The meaning of J2G3 indicates that the delivery state of S355J2G3 steel is normalized, the impact energy at - 20 ℃ is 27J. G3 and G4 indicate the deoxidization mode. S500MC tensile strength, S355J2G3 steel is semi killed steel, S355J2G4 steel is fully killed steel.

Training is one of the important factors in the construction of corporate culture. Online training system can be used to enable all employees to take advantage of fragmented time and carry out targeted training anytime and anywhere without the limitation of time and region. Through training to improve work skills, at the same time, through training, let all improve their quality education level, let employees work around a goal, create a career, and produce results.
