What is equivalent material of usage of nm450 sheet

The use of low carbon steel is limited due to its low strength. The strength of the carbon steel can be greatly improved by properly increasing the manganese content in the usage of NM450 sheet carbon steel and adding some alloy elements such as vanadium, titanium and niobium. If the carbon content in the carbon steel is reduced and a small amount of aluminum, boron and carbide forming elements are added, the ultra-low carbon bainite can be obtained, usage of NM450 sheet which has high strength and good plasticity and toughness.

The alloy layer of clad wear-resistant plate is mainly made of chromium carbide, and it is also equipped with molybdenum, niobium, titanium, boron and other components. The formation of multi-element carbides also has strong stability at high temperatures and can still be maintained below 500 °. High hardness and good oxidation resistance. The new clad wear-resistant plate usage of NM450 sheethas multiple performances of wear resistance, corrosion resistance, temperature resistance and impact resistance.

Quenching is a heat treatment process in which steel parts are heated to above the critical temperature, and after proper heat preservation, the parts are quickly cooled to room temperature in water or oil, so that martensite transformation occurs. The hardness of the quenched usage of NM450 sheet increases sharply. Quenching is to prepare the organization for adjusting and improving the performance of usage of NM450 sheet during tempering, while tempering determines the performance and life of the workpiece.
