The company can provide the dimensions, shape, weight, technical requirements, test methods, inspection rules, packaging, markings and quality certificates of high-quality carbon structural steel hot-rolled steel plates and strips. Carbon and alloy steel grades 15Cr, 20Cr, S890QL hardness, 30Cr, 35Cr, 40Cr, 45Cr, 50Cr, 38CrSi, 12CrMo, 15CrMo, 20CrMo, 25CrMo, 30CrMo, 35CrMo, 42CrMo, 50CrMo, 12CrMoV, 35CrMoV, 12Cr1MoV, 25Cr2Mo1V, 38CrMoA1, 40CrV, 50CrV , 15CrMn, 20CrMn.

Compared with the traditional seamless steel pipe, alloy seamless pipe has better performance in all aspects. Because of the addition of various metal elements in the manufacturing, the overall strength of the alloy seamless pipe is larger, stronger and durable, and the service performance and service life of the S890QL hardness, alloy seamless pipe are improved. The alloy seamless pipe is the best choice especially for special environment and high pressure requirements. Because of its high material properties, alloy seamless pipe has good corrosion resistance. It is not easy to be corroded in some special environment, which reduces the cost of the project and has a longer service life.

If the chromium content in S890QL hardness 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.
