S50C steel characteristics: the carbon content of the steel (mass fraction, %) ≥ 0.4, excellent wear resistance, reduced ductility, easy to deform and crack after quenching, so quenching is extremely important, and it must be quenched after cutting and tempering to avoid tempering brittleness. By implementing spheroidizing treatment, the cutting performance of this type of carbon steel keyword} can be improved. The steel is usually used after tempering to a hardness of 19~22HRC to increase its cutting performance.

From the name, we can clearly know that seamless pipe is seamless steel pipe, which is different from welded pipe. Seamless pipe is actually a kind of steel with hollow section. NM400 weathering steel, Seamless pipe has many advantages, such as: 1, the compressive capacity of seamless pipe is very good, the place with high bearing strength will not crack, and its bearing capacity is very good. 2. Seamless pipe has no welding point, so it is more corrosion-resistant and can bear larger pressure.

The purpose of NM400 weathering steel 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 NM400 weathering steel. 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.
