Cold Rolled Automotive Steel B410LA

Cold Rolled Automotive Steel B410LA steel is low carbon steel added with a little alloy elements such as niobium and/or titanium, which will be allowed to form carbide and nitride with carbon and nitrogen and separate these carbide and nitride out of ferritic matrix to increase steel strength. With excellent formability and relatively high strength, it is mainly used for manufacturing structural parts of automobiles such as chairs and cross beams.
