nm450 steel elongation professional supplier

40Cr steel is one of the most widely used steels for mechanical operations The hardenability of this steel is outstanding, it can be hardened to Ф28 ～ 60mm when water quenching, and Ф15 ～ 40mm when oil quenching In addition to quenching and tempering treatment, 40Cr steel is also suitable for cyanidation and high frequency quenching treatment 40Cr steel has good cutting performance When the hardness is 174 ～ 229HB, the relative machinability is 60% The steel is suitable for making medium-sized plastic molds,NM450 steel elongation.

Weathering steel has good resistance to atmospheric corrosion. Although the initial investment cost of weathering steel is slightly higher than that of ordinary carbon steel. Compared with methods such as spraying anticorrosive coating on the surface of ordinary carbon steel, the later maintenance costs of ordinary carbon steel are weathering steel. 1.5-2 times. Therefore, NM450 steel elongation weathering steel can reduce environmental pollution and is a key promotion technology for energy saving and emission reduction Most domestic weathering steels are painted and used, and their original intentions of no-painting and "rust prevention" have not been exerted to a greater extent,NM450 steel elongation.

NM450 steel elongation,Tempering the important welding structure often use high temperature tempering to remove residual weld stress. Classification: high temperature tempering above 400 ℃, medium temperature tempering 250 ~ 400 ℃, low temperature tempering 150 ~ 250 ℃, Quenching +Tempering is improve strength, plasticity and toughness.
