Development of wear-resistance of nm500 in China

We are a popular factory, supplier and wholesaler of mild steel plates and alloy steel plates in all over the globe. We follow all standards and specifications of wear-resistance of NM500 boiler steel plate, structural steel plate, shipbuilding steel plates and corten steel in different types. We manufacture and supply steel plates, steel section and steel structures according to customer’s demand. The company also focus on providing customers with wear-resistance of NM500 high-end steels and competitive price.

Q690D steel belongs to high-strength welded structural steel. Among them, Q represents the yield strength, 690 represents the yield strength value, and D represents the grade of the steel plate. The quality grades of common Q690 series steel are A, B, C, D, E. The impact of grade D steel plate is -20°C. Q690D steel can be called a low temperature resistant high strength steel with a yield strength of 690Mpa.

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. wear-resistance of NM500, 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.

Quenching is a common heat treatment process. It is the metal heat treatment process in which the wear-resistance of NM500 metal workpiece is heated to a proper temperature and kept for a period of time, then immersed in the quenching medium for rapid cooling. Quenching can improve the strength and hardness of steel in a large range, and adjust the coordination between wear-resistance of NM500 strength and hardness, plasticity and toughness. Quenching is generally used as the final heat treatment.
