The heat treatment knowledge of hardox 450 steel mechanical properties

The surface hardness of NM400 wear-resistant steel plate usually reaches 360-450HB, and the steel has a high mechanical strength. Its mechanical properties are three to five times that of ordinary low alloy steel plate. NM400 wear-resistant steel plate has excellent mechanical properties and good wear resistance, and can adapt to various mining conditions under different working conditions. NM400 steel can significantly improve the wear resistance of mechanical components, improve the service life of machinery, and reduce production costs.

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 Hardox 450 steel mechanical properties 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 Hardox 450 steel mechanical properties etc. steel is strictly controlled.

Hardox 450 steel mechanical properties, Large diameter spiral steel pipe refers to the relatively large diameter spiral steel pipe, which is generally required to be more than 1000mm. The manufacturing process of large-diameter spiral steel pipe: first, the steel strip is bent into shape, and then welded together to make a large-diameter spiral steel pipe of specified size. After being processed into a pipe, hydrostatic test, bending, flattening and other tests shall be carried out, and the internal steel support of large-diameter spiral steel pipe can be made according to customer requirements.

The related factors of Hardox 450 steel mechanical properties steel plate cutting are mainly steel plate material, steel plate specific use and steel plate cutting requirements, so it can be said that there are many related factors. Different processing methods, such as finish machining and rough machining, choose different Hardox 450 steel mechanical properties steel plate cutting methods. Wire cutting or plasma cutting is used for finishing and flame cutting is used for rough machining. Therefore, it can be concluded that the steel plate cutting methods selected under different processing methods are different.
