The density of nm450 plate application

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 NM450 plate application 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 NM450 plate application etc. steel is strictly controlled.

"The latest data from the General Administration of Customs shows that from January to February 2020, China exported 500,000 tons of coal and lignite, a year-on-year decrease of 60.2%. From January to February, China exported 360,000 tons of coke and semi-coke, a year-on-year decrease of 474.2%. From January to February, China imported 68.06 million tons of coal and lignite, a year-on-year increase of 33.1%."

The company's main business: ship plate, NM450 plate application low alloy plate, automobile steel, high-strength plate, pipeline steel, boiler steel plate, weathering plate, wear-resistant plate, bridge plate, pressure vessel plate, steel plate, steel processing, etc. The company takes the implementation of high-end, NM450 plate application high-quality, deep processing, strengthening the main business, diversified operation, group operation, enterprise transformation and upgrading as its development strategy, and makes all efforts to be your professional NM450 plate application steel supplier and partner.

The alloy layer of clad wear-resistant plate is mainly made of chromium carbide, and it is also equipped with molybdenum, niobium, titanium, boron and other components. The formation of multi-element carbides also has strong stability at high temperatures and can still be maintained below 500 °. High hardness and good oxidation resistance. The new clad wear-resistant plate NM450 plate applicationhas multiple performances of wear resistance, corrosion resistance, temperature resistance and impact resistance.
