SSAB, Sweden, announces that during the next 12 months it will release two hot-rolled advanced high-strength steel grades that exceed 800 and 1000 MPa in tensile strength for automobile chassis applications.
“The steels offer a unique combination of properties for maximized hole expansion and edge ductility,” says José Puente Cabrero, Portfolio manager, automotive products.
SSAB is a producer of advanced high-strength steels for the transport and automotive industries. These steels help designers and manufacturers meet new, exacting demands from industry and customers to reduce weight and CO? emissions, increase cost efficiency, and improve crashworthiness. Through close collaboration with customers, research institutes, and universities, the R&D department at SSAB has created a series of new alloys.
SSAB will also introduce new cold-rolled martensitic steels with improved flatness. The latest Docol martensitic steels for cold-formed applications, with a tensile strength above 1700 MPa, are being designed into upcoming car models.
Up to now, higher tensile strength has affected the ductility of advanced high-strength steel products. “Now we are going to introduce new press-hardening steels. These are optimized to reach tensile strengths above 2000 MPa, but with retained good ductility,” says Mr. Cabrero.
