Material Name: High quality carbon structural steel
Standard: GB/t 5213-1985
Characteristics and scope of application:
Al Deoxidation is a high-quality carbon structural steel, for thickness 0.8~3.0mm deep stamping low carbon cold-rolled thin steel plate. Compared with ordinary cold-rolled sheet steel, it has better comprehensive mechanical properties and formability. Widely used in a variety of vehicles in the shape of complex deep stamping parts. such as car, tractor body, cab, engine shell, such as not withstanding the load of various stamping parts.
