Q960 quenched and tempered steel grade classification: Q960C, Q960D, Q960E, Q960F. The product stal S420M thickness is not more than 150MM. Q960 quenched and tempered steel has high yield strength and tensile strength, and its resistance to brittle failure is also great. Q960 quenched and tempered steel has excellent low temperature toughness, so it can be used in large welded structural parts and low temperature environments.

The surface of alloy steel coil is specially treated during processing. The wear resistance of steel coil and plate made of alloy steel is much better than that of traditional rolling plate, and the cost is also low. The heat resistance and high temperature resistance of alloy steel coil is better than that of traditional rolling plate, and it will not deform easily. Besides, the strength of the stal S420M, alloy steel is very high, it is not easy to break and can be used for a long time.

Oxygen (O) is a harmful element in steel such as stal S420M. Although manganese, silicon, iron and aluminum are added to deoxidize the steel at the end of steelmaking, they can not be removed completely. During the solidification of molten steel, the reaction of oxygen and carbon in the solution will produce carbon monoxide, which can cause bubbles. Oxygen mainly exists in the form of FeO, MnO, SiO2, Al2O3 and other inclusions in the steel, which reduces the strength and plasticity of the steel. Especially, it has serious influence on fatigue strength and impact toughness.
