usage of NM400 steel plate black surface

S45C steel plate chemical composition: C 0.42~0.48, Si 0.15~0.35, Mn 0.60~0.90, P≤0.030, S≤0.035, Cu≤0.30, Ni≤0.20, Cr≤0.20Mechanical properties of usage of NM400 steel plate productTensile strength>686MPaYield strength>490MPaElongation δ5>17%Shrinkage ψ>45%Impact toughness value>78J/cm2The hardness is 201~269HB.

usage of NM400 steel plate, 09CrCuSb steel has the following advantages: 1. The alloy ratio is optimized and rare alloy is added. The finished steel product has excellent sulfuric acid uniform corrosion resistance. 2. The content of As, Sn, Pb and other elements, and the gas content of hydrogen, oxygen and nitrogen are controlled to improve the purity of the billet. According to the analysis of many times, the grain size of the material is not coarser than grade 6. The corrosion resistance of the equipment made of 09CrCuSb steel is improved, and the maintenance cycle is relatively prolonged, which has great economic benefits.

If the chromium content in usage of NM400 steel plate alloy steel reaches about 12%, dense chromium oxides will be formed on the surface of the steel, which will greatly improve the corrosion resistance of steel in oxidizing media. Chromium, aluminum, silicon and other elements can improve the oxidation resistance of steel and the corrosion resistance of high-temperature gas, but excessive aluminum and silicon will deteriorate the thermoplasticity of steel.
