Carbon nm400 steel equivalent for steel pipe

The company is a leading steel production and exporting group in steel materials with advanced production technology, metal-cutting skill, and steel structures engineering projects. We can supply carbon steel plate and sheet, alloy steel plates and structural NM400 steel equivalent steel plates. These hot rolled steel plates are sturdy plates having high quality. Their imperviousness to effect and scrapped area, weld capacity, and workability make them a worthy product in a variety of industries.

The company specializes in steel plate cutting, steel plate processing and wide thick plate, hot rolling coil. The company possesses advanced CNC steel plate cutting processing equipment, first-class technical personnel, supporting marketing and after-sales service system. Steel plate cutting parts are mainly used in mechanical manufacturing, shipbuilding, steel structure and mold processing industries, and we can provide NM400 steel equivalent, finished products and semi-finished products processing according to the needs of users.

Compared with carbon steel, low alloy steel has many advantages, such as high strength, good plasticity and toughness, good weldability, good cold and hot pressure processing performance, better corrosion resistance, etc. Due to the increase of NM400 steel equivalent metal composition, the yield point of low alloy steel structure is higher than that of ordinary carbon steel, so it is light and suitable for structural parts application. The low alloy steel is one of our main products.

Tempering includes high temperature tempering, medium temperature tempering and low temperature tempering. Tempering means to reheat the NM400 steel equivalent quenched steel to a certain temperature and then cool it in a certain way. Tempering can reduce or eliminate the internal stress produced by quenching, reduce the hardness and strength, and improve the ductility or toughness of steel. After NM400 steel equivalent quenching, the workpiece should be tempered in time, and the required mechanical properties can be obtained through the combination of quenching and tempering.
