Abstract

Abstract: Hot stamping process of a2 GPa hot forming steel with high toughness was studied, as well as its performances of spot welding, bending, tensile, anti-delayed fracture and coating anti-corrosion performance. The results show that the recommended process for the tested steel is heating at 910-930 ℃ for 240-300 s,with thepressure holding time of 7-15 s.Under this process,the tested steel has good application performances, as the spot welding, bending, tensile, anti-delayed fracture and coating anti-corrosion performances meet or exceed the requirements of relevant standards.

Key words: 2 GPa grade, hot forming steel, high toughness, strengthening mechanism, application performance
