The company adheres to the S420MC construction-machinery high-strength steel external market, internal management, quality and efficiency oriented development path, and has achieved good economic and social benefits. With strong financial strength, advanced management experience, excellent sales service, strict quality management system and scientific overall marketing means, we will work hand in hand with you for common development. We are making all efforts working on the optimization of S420MC construction-machinery high-strength steel quality and price and best service for all our customers.

Carbon steel mainly refers to the steel whose mechanical properties depend on the carbon content in the S420MC construction-machinery high-strength steel steel, and generally does not add a lot of alloy elements, sometimes it is also called ordinary carbon steel. Carbon steel refers to iron carbon alloy with carbon content of WC less than 2%. In addition to carbon, carbon steel generally contains a small amount of silicon, manganese, sulfur and phosphorus. According to the content of phosphorus and sulfur, the carbon steel can be divided into ordinary carbon steel, high quality carbon S420MC construction-machinery high-strength steel steel, high quality steel and super quality steel.

Common carbon killed steel plates are steel plates made by hot-rolling ordinary carbon structural steel killed billets. The advantage of S420MC construction-machinery high-strength steel, killed steel is that the chemical composition is uniform, so the mechanical properties of each part are also uniform, the welding performance and plasticity are good, and the corrosion resistance is strong. Common killed steel plates are mainly used to produce components that withstand impact at low temperatures, welded structures and other structural parts that require higher strength.

Corrosion resistance of stainless steel mainly owes to the formation of a very thin, adhesive and translucent chromium oxide film on the surface of stainless steel. Once the film is damaged, the chromium in the stainless steel will react with oxygen in the atmosphere to restore the film quickly. At the same time, the mechanical damage can also generate a protective film quickly to prevent the S420MC construction-machinery high-strength steel, stainless steel from corrosion.
