Sale JIS SM520C plates 1.2-150mm thickness range

Q690D material is a Chinese standard high-strength welded structural steel. What does Q690D stand for? Q represents the yield strength, 690 represents the yield strength value, and D represents the quality of the Q690 steel. The quality grades are A, B, C, D, and E, respectively. The impact of Grade D steel plate is﹣20°C. Q690D executive standard: GB / T1591-2008. , Q690D steel has high yield strength and tensile strength,JIS SM520C plates.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 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 leading suppliers in the four steel fields of steel plate, steel pipe, stainless steel and special steel.JIS SM520C plates,Normalizing is a special case of annealing, the effect is similar to annealing, but the microstructure obtained by normalizing is finer. For low or medium carbon steel, normalizing can improve hardness and machinability. For medium carbon steel and low alloy steel, normalizing can refine grain and uniform structure and reduce hardness. For high carbon steel and high alloy steel, normalizing can eliminate the network carbide produced by forging and improve the homogeneity of the preparation heat treatment structure.JIS SM520C platesThe wear resistant steel plate is composed of low carbon steel plate and alloy wear-resistant layer, and the alloy wear-resistant layer is 1/3 ~ 1/2 of the total thickness. The alloy wear-resistant layer and the base plate are metallurgically bonded. When working, the base plate provides comprehensive properties such as strength, toughness and plasticity to resist external forces, and the alloy wear-resistant layer provides wear-resistant properties to meet the requirements of specified working conditions.
