With high-quality auto steel S 420 MC, S500MC, S700MC steel and professional services, we have won international praise in infrastructure, shipbuilding, oil and other industries, and gradually grow into a bright star in the steel export industry, while winning unanimous praise from foreign customers. It has laid a foundation for the development of our auto steel S 420 MC, S500MC, S700MC steel market and improved the control of steel plate production quality.

API 5L X42 steel plate/pipes for large diameter pipes X42 steel plate/pipes, API 5L X42 steel plate/pipes, under API 5L standard, we can regard X42 steel plate/pipes as large diameter pipes. auto steel S 420 MC, S500MC, S700MC, X42 steel plate/pipes is one mainly of Steel for large diameter pipes,API-X42 steel used for pressure liquid transport, oil, gas, water and other liquid transportation, oilfield engineering, ductwork, construction, steel pipe and oil and gas project which use pipes.

Low-alloy steel plates have low carbon content, and because ferrosilicon is not used for deoxidation, the silicon content in steel is often <0.07%. The outer layer of rimmed steel is crystallized in a rimmed state, so the surface layer is pure and dense, the surface quality is good, and the Zhengzhou low alloy steel plate auto steel S 420 MC, S500MC, S700MC has good processing performance. Rimmed steel does not have large concentrated shrinkage cavities, uses less deoxidizer, and the cost of steel is low.

30CrMo 35CrMo 25CrMo4 42CrMo4 and so on CrMo steels have good mechanical properties and hydrogen resistance at room temperature and high temperature. The main alloy elements in CrMo steel are molybdenum, chromium, vanadium, silicon, boron, etc. Molybdenum is a very important alloy element in the hot strength steel. It can significantly improve the hot strength of the CrMo steel, maintain sufficient strength at high temperature, refine the grains and prevent the overheating tendency of the CrMo steel, auto steel S 420 MC, S500MC, S700MC.

Chemical elements of 42SiMn steel: C: 0.39-0.45, Si: 1.10-1.40, Mn: 1.10-1.40. Mechanical properties of 42SiMn steel: tensile strength 885 MPa; yield strength 735 MPa; elongation after fracture: 15; reduction of area: 40; impact energy: 47J. 42SiMn steel belongs to alloy quenched and tempered steel with good properties, high strength, wear resistance and hardenability. Under certain conditions, the strength, wear resistance and hot working performance of 42SiMn steel are better than 40Cr steel, auto steel S 420 MC, S500MC, S700MC, and can be used instead of 40CrNi steel.
