GB stadard of nm500 steel exported to Nigeria

Beijing machining center has more than 1000 employees, including 360 technicians, 28 engineers, 6 senior welders, 15 professional welders, 52 bachelor's degree, 3 doctor's degree, and 8 R & D team. It is a professional GB stadard of NM500 steel production team combining theory and practice. With an annual output of 80000 tons, looking forward to the future, our company continues to strengthen the advantages of GB stadard of NM500 steel leading suppliers in the four steel fields of steel plate, steel pipe, stainless steel and special steel.

Automobile steel sheet is mainly used to manufacture automobile girders (longitudinal and cross girders), frame and other structural parts. The automobile girder should not only bear heavy static load, but also bear certain impact, vibration, etc., so the steel sheet GB stadard of NM500 steel is required to have certain strength and fatigue resistance, as well as better stamping performance and cold bending performance to meet the requirements of cold stamping processing.

Bridge steel plates are thick steel plates made of carbon steel and low-alloy steel for bridge construction. The main applications of bridge steel plates are to build railway bridges, highway bridges, and sea-crossing bridges. The bridge steel plates are required to have high strength, durability and bear the load and impact of rolling stock. Bridge steel plates have good water resistance, low thermal conductivity, flat and lubricated surface. The main grades of bridge steel plates are A709 grade 50, A588 grade B, GB stadard of NM500 steel and so on.

Quenching is a heat treatment process in which steel parts are heated to above the critical temperature, and after proper heat preservation, the parts are quickly cooled to room temperature in water or oil, so that martensite transformation occurs. The hardness of the quenched GB stadard of NM500 steel increases sharply. Quenching is to prepare the organization for adjusting and improving the performance of GB stadard of NM500 steel during tempering, while tempering determines the performance and life of the workpiece.

"ASTM A516 Grade 70 plate is a boiler / pressure vessel quality of steel plate for use in low to moderate services. It has improved notch toughness. GB stadard of NM500 steel, A516 Grade 70 steel plates can be produced with thick up to 200mm.For boiler steel plate A516 Grade 70, the yield strength shall be above 260 Mpa, tensile strength from 485 Mpa to 620 Mpa.A516 Garde70 steel plate is equivalent to the P355GH and 490B grades. "
