We can process and cut all kinds of special-shaped parts according to your requirements, or we can set and roll futures of all kinds of material specifications according to your requirements, with fast delivery time. We sincerely welcome new and old customers from all walks of life to contact us for NM400 steel for vehicle business negotiation. With the enthusiasm, good reputation and professionalism of our staff, we will provide excellent services to our valued customers in all aspects, so as to achieve common development and prosperity.

Flat NM400 steel for vehicle steel plate, with a small thickness of the plate. Low carbon equivalent, to adapt to automatic submerged arc welding, plasma welding and other NM400 steel for vehicle welding process requirements.

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 NM400 steel for vehiclehas multiple performances of wear resistance, corrosion resistance, temperature resistance and impact resistance.

The final heat treatment of quenched and tempered alloy steel, NM400 steel for vehicle is quenching and high temperature tempering. The hardenability of quenched and tempered alloy steel is high, and oil is generally used. When the hardenability is very high, it can even be air cooled, which can reduce the defects of heat treatment. The final properties of quenched and tempered alloy steel depend on tempering temperature. Generally, it is tempered at 500 ℃ - 650 ℃. The required properties can be obtained by selecting tempering temperature. In order to prevent the second kind of temper brittleness, fast cooling (water cooling or oil cooling) after tempering is beneficial to the improvement of toughness.
