Which elements in SM490A carbon steel plate sheet

Sulfur is a very harmful element in SM490A carbon steel plate sheet steel. The presence of sulfur will increase the hot brittleness of steel, reduce the various mechanical properties of SM490A carbon steel plate sheet steel, and reduce the weldability, impact toughness, fatigue resistance and corrosion resistance of steel.

Low welding crack sensitivity high-strength steel plate, today mainly introduces Q620CF, with three grades C, D, E. The grades of low-welding crack sensitivity high-strength steel plate: Q460CFC, Q460CFD, Q460CFE, Q500CFC, Q500CFD, Q500CFE, Q550CFC, Q550CFD , Q550CFE, Q620CFC, Q620CFD, Q620CFE, Q690CFC, Q690CFD, Q690CFE, SM490A carbon steel plate sheet, Q800CFE. It is mainly used for the production of hydropower penstocks, construction machinery, railway vehicles, bridges, high-rise and large-span buildings that require high weldability.
