ST37 SS490 H Beam Steel

The chemical composition of St37 steel plays a fundamental role in determining its physical and mechanical properties, with the primary constituents being iron, carbon, and manganese. The steel's versatility and strength are directly influenced by these components, which define its durability, corrosive resistance, and thermal conductivity.

The NMening process, which involves heating the steel above its critical temperature and then rapidly cooling it, further enhances these properties. This process changes the steel's microstructure, increasing its NMness and strength.

Moreover, the carburizing process can also be used to improve St37 steel's mechanical properties. This thermochemical treatment enriches the steel's surface layer with carbon, thereby enhancing its wear resistance. Care must be taken, however, to ensure the carbon content in the surface layer does not exceed 0.9%, as this could lead to the formation of cementite and increase the steel's vulnerability.

Our factory has complete production facilities, and provides laser cutting , bending, welding, painting, assembly and other processing services.

We have own large-scale indoor warehouse with perennial spot stocks totally above 5000 tons mainly include 2000 tons galvanized

steel series and 2500 tons carbon steel series

All the products have to pass the inspections such as tension test, NMness test, spectrophotometer test, salt spray test and PH

test before leaving the factory .
