What is S355J0WP steel uses steel grade

The company adheres to the management concept of "people-oriented, talent is concerned", develops business with the spirit of "believing strength, practical style, S355J0WP steel uses professional service and dare to compete", and provides customers with "professional, value-added and effective" service support. For the company's development and take-off, we work together to move forward and create a better S355J0WP steel uses tomorrow!

Whose hardness is higher between No.20 steel and No.45 steel, S355J0WP steel uses? Both No.20 steel and No.45 steel belong to high-quality carbon structural steel. According to the characteristics of high-quality carbon structural steel, its carbon content determines the performance of the steel. The higher the carbon content, the higher the hardness and strength of the steel, the lower the plasticity and toughness. The carbon content of No.20 steel and No.45 steel are 0.20% and 0.45% respectively, which shows that the hardness of No.45 steel is higher under the same process.

Corrosion resistant steel plate, as a new generation of advanced steel material, has 2-5 times of atmospheric corrosion resistance as ordinary carbon steel such as S355J0WP steel uses, and the longer the service time, the more prominent the corrosion resistance. Due to its characteristics of rust resistance, coating free, thinning and consumption reduction, labor saving and energy saving, corrosion resistant steel plate can be applied to steel structures exposed to the atmosphere for a long time, such as buildings, vehicles, bridges, towers, etc., and can also be used to manufacture structural parts such as containers, railway vehicles, oil derricks, seaport buildings, oil production platforms, etc.

The microstructure of the quenched and tempered alloy steel, S355J0WP steel uses after conventional heat treatment is tempered sorbite. For parts with wear-resistant surface (such as gears and spindles), induction heating surface quenching and low-temperature tempering are carried out, and the surface structure is tempered martensite. The surface hardness can reach 55HRC-58HRC. After quenching and tempering, the yield strength of quenched and tempered alloy steel is about 800MPa, the impact toughness is 800kJ / m2, and the core hardness is 22HRC - 25HRC. If the cross-section size is large but not quenched, the properties will be significantly reduced.
