price of NM400 steel consumption reached a historical record in 2020

Phosphorus element (P element) is brought into steel by ore. Generally speaking, phosphorus is also harmful element. Although phosphorus can increase the strength and hardness of price of NM400 steel etc. steel, it also causes the decrease of plasticity and impact toughness. Especially at low temperature, it makes steel significantly brittle, which is called "cold brittleness". The higher the phosphorus content is, the greater the cold brittleness is. Therefore, the phosphorus content in price of NM400 steel etc. steel is strictly controlled.

The alloy wear-resistant layer of price of NM400 steel, wear-resistant steel plate is mainly composed of chromium alloy, and other alloy components such as manganese, molybdenum, niobium and nickel are added. The carbide in the microstructure is fibrous distribution, and the fiber direction is vertical to the surface. The alloy carbide has strong stability at high temperature, maintains high hardness, and has good oxidation resistance. It can be used normally within 500℃.

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, price of NM400 steel plate processing, and steel distribution, also have large warehouse and processional representatives both inTianJin, Zhengzhou and Beijing city.
