Chemical composition of nm550 steel wear resistance

In recent years, in line with the development trend of iron and NM550 steel wear resistance steel industry at home and abroad, we have accelerated the transformation of development mode, promoted structural adjustment, and formed a rich product series of medium and thick plates, hot rolled steel coils, profiles, steel pipes, etc., which NM550 steel wear resistance are widely used in automobiles, long-span bridges, railways, machinery, ocean and so on fields. Meanwhile, we also provide deep processing for the steel materials.

Flat NM550 steel wear resistance steel plate, with a small thickness of the plate. Low carbon equivalent, to adapt to automatic submerged arc welding, plasma welding and other NM550 steel wear resistance welding process requirements.

Compared with ordinary steel, the NM550 steel wear resistance special steel has the following characteristics. First, the special steel has better physical properties, higher strength, stronger compressive strength, and better precision. Second, the special steel has better chemical properties, such as high temperature resistance, low temperature resistance and corrosion resistance. Third, the composition of the special steel is more diversified, which can be synthesized by integrating other elements, such as alloy steel, high carbon steel, etc. Fourth, special steel is more flexible for processing.

NM550 steel wear resistance annealing is to heat the steel to 30 ~ 50℃ above the critical temperature, keep it in the heat treatment furnace for a period of time, and then cool it down to room temperature with the furnace. The purpose of NM550 steel wear resistance annealing is to refine the grain of steel, eliminate internal stress and reduce hardness, improve cutting performance, increase toughness and plasticity, and facilitate welding and rolling processes. NM550 steel wear resistance annealing can be complete annealing, incomplete annealing, stress relief annealing, isothermal annealing and spheroidizing annealing.

NM550 steel wear resistance, SA36 steel plate is one of our main product, it is belong to the carbon and low alloy high strength steel plate. We can supply the different sizes of SA36 steel plate. And the rolling size of SA36 steel plate is following: the thickness range is 1.2-600mm, the width range is 1220-4200mm, and the length range is 5000-18000mm. Also note that the SA36 steel coil thickness should not exceed 25 mm.

Both parties shall confirm the NM550 steel wear resistance material object and the quality of the products, confirm the reasons for the defects and the quality of the products, and sign the quality inspection agreement. Major quality objections shall be reported to relevant leaders in a timely manner, and shall be discussed and solved with the NM550 steel wear resistance steel plant.
