What is the s355j2 hardness process flow

BBN steel company was founded in 2000, starting the international business in 2010 and successfully being approved and certified by ISO9001:2008. After ten years development, BBN steel has become the large-scale comprehensive enterprise group, combining steel trading, s355j2 hardness plate processing, and steel distribution, also have large warehouse and processional representatives both inTianJin, Zhengzhou and Beijing city.

Application of 30CrMnSiA steel, s355j2 hardness:30CrMnSiA steel is generally used after quenching and tempering. 30CrMnSiA steel is mainly used to manufacture various important parts with high load and high speed, such as gears, shafts, clutch friction plates, sprocket wheels, grinding wheel shafts, shaft sleeves, bolts, nuts, etc. 30CrMnSiA steel is also used for manufacturing wear-resistant parts with low working temperature and variable load welding components, such as blades, valve plates and non corrosive pipes and pipes of high-pressure blowers.

NM series wear-resistant steel plates have uniform hardness, avoid the local fracture phenomenon caused by uneven hardness. Compared with ordinary steel plate, NM360 steel plate has wear resistance of not less than twice, NM400 steel plate has wear resistance of not less than 2.5 times, and NM550 steel plate has wear resistance of not less than 4 times. The wear-resistant steel plate combines the characteristics of high strength, high hardness, weldability and easy bending.

Between alloy wear-resistant layer and the substrate of wear-resistant steel is metallurgically bonded. Through special equipment and automatic welding process, high-hardness self-shielding alloy welding wire is uniformly welded on the substrate, and the number of composite layers is one to two or even multiple layers. During the compounding process, due to the different alloy shrinkage ratio, uniform transverse cracks occur. It is a distinctive feature of wear-resistant steel plates, s355j2 hardness.
