In recent years, with the development of the construction industry, the demand for S355J0 carbon steel plate is also increasing. In order to improve the quality of S355J0 carbon steel plate, many industrial enterprises have started to innovate the steel smelting process. We all know that some additives will be added in the steel smelting to remove some impurities in the molten steel, which can improve the quality of S355J0 carbon steel plate, but in the steel There are also some elements that have a good effect on the quality of steel.
1. Carbon: the carbon content of S355J0 carbon steel plate increases, the yield point and tensile strength increase, but the plasticity and impact are reduced, the high carbon content will also reduce the atmospheric corrosion resistance of S355J0 carbon steel plate, and the high carbon steel in the open yard is easy to rust; In addition, the carbon can increase the cold brittleness and aging sensitivity of S355J0 carbon steel plate.
2. Chromium: chromium can increase the hardenability of S355J0 carbon steel plate and has the effect of secondary hardening. It can improve the hardness and wear resistance of S355J0 carbon steel plate without embrittlement. Chromium is the main alloy element of stainless steel acid resistant steel and heat resistant steel.
3. Nickel: nickel can strengthen ferrite and refine pearlite in S355J0 carbon steel plate. The overall effect is to improve the strength, but the effect on plasticity is not significant. Generally speaking, the strength of S355J0 carbon steel plate can be improved without significantly reducing its toughness when the low carbon steel is used in rolling, normalizing or annealing state without quenching and tempering treatment.
Through the knowledge sharing of each element in S355J0 carbon steel plate, we will not remove them all as impurities when we analyze the steel smelting process. We produce various sizes of S355J0 carbon steel plate. If you have any demand, please contact us directly! We will provide you with the best quality S355J0 carbon steel plate!
