What is the hardness of nm450 sheet manufacturers in China

How to improve the wear resistance of wear-resistant plate, hardness of NM450 sheet?1. Grain refinement to promote the increase of dislocation density under stress state.2. Reduce the Mn content to reduce the Austenite Stability of wear-resistant plate and achieve the ability of accelerated work hardening.3. Cr, Mn, V, Ti and other elements are added to improve the wear resistance of the wear-resistant plate, and the carbide is dispersed in austenite to enhance the wear resistance.

we also provide the hardness of NM450 sheet welding service for customers, and our welding method, hand arc welding, submerged arc welding and tungsten argon arc welding, melting polar gas shielded welding and so on. And we have lots of successful hardness of NM450 sheet welding project, such as longitudinal submerged arc welding pipe, welding cross colume, prestressed truss and welding box colume.

"As Covid 19 spreads around the world, all unnecessary businesses and factories have been closed in Italy this week. South Korea's POSCO, the world's fifth-largest steelmaker, announced on March 24th that it would close its hardness of NM450 sheet wire-processing centre near the northern Italian city of Verona from Thursday March 26th until April 3rd. POSCO has already closed two wire-processing centres in Delhi and Pune. Two wire processing centers in Malaysia and Thailand also announced last week that they will be closed until March 31."

On November 25, the price of the hardness of NM450 sheet medium board in the Yinchuan market remained stable temporarily, and the market transactions were average. As of press time, Yinchuan market 16-25mm general medium plate is 4020 yuan/ton; 14-25mm low alloy medium plate is 4170 yuan/ton. The price of plate in Yinchuan market continued to stabilize without much change. However, as the temperature dropped sharply and terminal demand in the local market dropped to a low point, plate merchants in the Yinchuan market had difficulty shipping.
