We have an adept and proficient team of professionals in addition to our responsive staff that is ever alert for any customer queries and requisites. If you are experiencing difficulty in selecting the correct SMA400AW weather resistant steel section steel plates for your business, we have a team of experts who can give you the best advice on steel plates, a significant contributor that can flourish your business.
SMA400AW weather resistant steel section, 40Cr material is a common machinery manufacturing steel under GB/T 3077-2015 standard. After tempering, it has good comprehensive mechanical properties, good low temperature impact toughness and low notch sensitivity. The hardenability of steel is good. It can be hardened to Ф28-60mm during water quenching and Ф15-40mm during oil quenching. The cutting performance is better, when the hardness is HB174 -229, the relative cutting workability is 60%.
SMA400AW weather resistant steel section and so on steel structure engineering steel has good plasticity, which can make the structure have obvious deformation before being destroyed, so as to avoid brittle failure of structure. The good plasticity of steel can adjust the local peak stress to redistribute the stress, and improve the ductility of components, so as to improve the seismic capacity of the structure. The impact toughness of SMA400AW weather resistant steel section and so on steel structure engineering steel is good, which can improve the ability of resisting dynamic load and avoid the occurrence of cracks and brittle fracture.
Decarburization in SMA400AW weather resistant steel section, wear resistant plate is an important reaction in steelmaking process. During the decarburization process, a large number of carbon monoxide bubbles are produced, which makes the molten steel temperature and chemical composition uniform, and can effectively remove the gas and non-metallic inclusions in the molten steel. Because decarburization can play such an important role, in steelmaking, the average carbon content of furnace charge always exceeds the specified carbon content of steel, so as to oxidize the surplus carbon in the oxidation period.
