Normalizing temperature of nm300 steel price list

RAEX400 steel is a hardened wear-resistant steel material with an average grade of 400HBW and a Brinell hardness. The microstructure of this wear-resistant steel is a martensite structure, which can ensure the high hardness and tensile hardness of the steel plate. The hardness of RAEX400 is 2.5 times that of S355 structural steel, nm300 steel price list. Despite its high hardness and high strength, RAEX400 steel can be formed by free bending or hemming, and has good weldability.

The sulfur element (S element) comes from the ore and fuel coke of steelmaking. It is a harmful element in nm300 steel price list etc. steel. Sulfur exists in steel in the form of iron sulfide (FeS). FeS and Fe form a low melting point (985℃) compound. The hot working temperature of steel is generally above 1150 - 1200℃, so when the steel is hot working, the premature melting of FeS compound causes the workpiece to crack, which is called "hot brittleness". It reduces ductility and toughness of steel and causes cracks during forging and rolling. Sulfur is also detrimental to welding performance and reduces corrosion resistance.

Steel strip is a branch of steel plate. Steel strip is a kind of narrow and long steel plate, also known as strip steel, nm300 steel price list produced by various steel rolling enterprises to meet the needs of different industrial departments and industrial production of various metal or mechanical products. The width of steel strip is within 1300mm, and the length is slightly different according to the size of each roll. Generally, nm300 steel price list steel strip is supplied in coils, with the advantages of high dimensional accuracy, good surface quality, easy processing and material saving. The steel strip is a kind of steel with large output, wide use and many varieties.
