JIS G3113 SAPH440 is steel for automobile. JIS G3113 SAPH440 automotive steel tensile strength is more than 440MPa. It has high strength and cold forming performance. JIS G3113 SAPH440 steel is usually in form of hot rolled / pickled SAPH440 steel strip, hot rolled / pickled SAPH440 steel coil, hot rolled / pickled SAPH440 steel sheet, hot rolled / pickled SAPH440 steel plate.
Compared with hot rolled SAPH440 steel, pickling SAPH440 steel has no change in base material, and is often used in occasions with higher surface quality requirements than hot rolled SAPH440 steel.
