How to protect the mechanical properties of nm300 steel from cracking

The mechanical properties of nm300 steel steel making furnace can only be used as primary refining, and the refining needs to be completed in the refining equipment outside the furnace, which is also called secondary refining. It is mainly through decarburization, desulfuration, denitrification and dephosphorization to improve the cleanness of the steel, to establish a chromium molybdenum low alloy steel with good oxidation resistance and high temperature strength, to remove unwanted harmful impurities from the steel, and to improve the mechanical properties of nm300 steel internal quality of the steel.

The defects of mechanical properties of nm300 steel, wear-resistant plate in rolling process can be divided into raw material defects, surface spot defects, plate shape defects and edge defects. The so-called raw material defects refer to some defects caused by raw materials and kept or remained in the cold rolling process. The defects of raw materials usually include bubbles, inclusions, iron sheet pressing in, raw material scratches and roll marks. The stain defect of wear-resistant plate is mainly caused by the oil on the surface of strip steel and the iron powder produced during rolling, which is left on the surface of strip steel after rolling.

Our company was founded in 2009, and has been committed to steel business since its establishment. Over the years, the company's performance shows a good development trend, with a wide range of customers in the government, domestic and foreign markets. The company has always been in line with the tenet of "based on trust and win with quality", focusing on the market demand, with a long-term vision, with years of hard work and trustworthy operation, and the support of the majority of mechanical properties of nm300 steel businesses and customers, has won the unanimous praise and trust of the industry and customers!

The company produces and export steel plates and steel section products of various materials all year round. The width of the mechanical properties of nm300 steel thin plate is 500 - 1500 mm; the width of the thick plate is 600 - 3000 mm. Steel plates are classified by steel type, including ordinary steel, alloy steel, spring steel, stainless steel, tool steel, heat-resistant steel, bearing steel, etc .; according to use, there are shipbuilding plate, pressure vessel plate, wear resistant steel plate, bridge builidng steel, corten steel plate, and pipeline steel plate.
