We can process and cut all kinds of special-shaped steel parts according to your requirements, and we can arrange fresh production for all kinds of NM400 steel grade steel materials in customized specifications. The company adheres to the core values of "quality and benefit, integrity and win-win, innovation and efficiency", and provides first-class services. Based on the principle of reputation first, small profits and high sales, we develop the market with high-quality services and flexible business model.
The gas cylinder steel coil and sheets are our main products. Our main conducted standards for gas cylinder steel coil and sheets are JIS G3116, GB6653, EN10120. The typical gas cylinder steel grades are SG255, SG295, SG325, HP265, HP295, HP325, P245NB, P265NB, P310NB, P355NB, etc. For the gas cylinder steel coil NM400 steel grade, we provide slitting, cutting, and stamping service. So as to meet different size and shape requirements of the customers. The gas cylinder steel coil and sheets are mainly used to make gas cylinders.
Both 14Cr1MoR pressure vessel steel and 15CrMoR pressure vessel steel belong to Cr-Mo hydrogen resistant steel, and they are special steel in strict sense. NM400 steel grade, Cr-Mo hydrogen resistant steel is suitable for petrochemical, nuclear power, steam turbine cylinder block, thermal power and other large-scale equipment with high temperature and high pressure and connected with hydrogen or hydrogen mixed medium. Moreover, 15CrMoR pressure vessel steel has high endurance strength below 550 °C.
Experiments have proved that the outstanding feature of the precipitation-strengthened NM400 steel grade, wear-resistant plate in terms of mechanical properties is that the yield strength is greatly improved. For example, the yield strength of the wear-resistant plate after precipitation strengthening treatment reaches 480-8l0MPa, and the yield strength ratio is 0.55-0.56; the wear-resistant plate that uses molybdenum, vanadium, and iron composite alloying, the yield ratio after dispersion strengthening is 0.60- 0.65.
