What is the difference between Is S355J2W carbon steel and A36 metals?

In recent years, in line with the development trend of iron and Is S355J2W carbon steel 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 Is S355J2W carbon steel 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.

Some Is S355J2W carbon steel, low-alloy high-strength steels have good atmospheric corrosion resistance, which can not only improve the effect of anti-corrosion coatings, but also in some cases take appropriate precautions and even be exposed to the atmosphere without coating. Elements that improve atmospheric corrosion resistance are copper, phosphorus, silicon, chromium, nickel, and molybdenum. The excellent atmospheric corrosion resistance has led to the formation of new concepts for structural design of buildings, bridges, and other structures.

Is S355J2W carbon steel, Chinese grade 45 steel belongs to high quality carbon structural steel. The application of Is S355J2W carbon steel, Chinese grade 45 steel depends on its various properties. Is S355J2W carbon steel, Chinese grade 45 steel has certain toughness and plasticity, high strength and good machinability. Good comprehensive mechanical properties of Chinese grade 45 steel can be obtained by quenching and tempering treatment. Chinese grade 45 steel is suitable for manufacturing high strength moving parts, such as air compressor, piston of pump, impeller of steam turbine, rolling shaft, connecting rod, worm, rack, gear and pin in heavy and general machinery.

Low alloy high strength steel is a kind of engineering structural steel developed by adding a small amount of Mn, Si and a small amount of Nb, V, Ti, Al and other alloy elements on the basis of carbon structural steel, Is S355J2W carbon steel. The so-called low alloy means that the total amount of alloying elements in steel is less than 3%. High strength is relative to carbon engineering structural steel. The development principle of low alloy high strength steel is to use as few alloy elements as possible to obtain as high comprehensive mechanical properties as possible, so as to meet the requirements of use and low cost.

Hardness comparison between Q345B steel and NM450 steel: wear resistant steel for construction machinery requires high wear resistance, high toughness, impact resistance, easy welding, easy forming and other high-performance characteristics. The main index of wear resistance is the surface hardness. The higher the hardness, the better the wear resistance. Compared with Is S355J2W carbon steel, Q345B steel, the hardness of NM450 steel is only increased 3 times, but the average service life is increased 6-8 times under the same working conditions.

Our company has its own steel plate manufacturing plant, processing plant and steel pipe plant.
