Formability of TS590 N/mm2 “Tri-Phase” Hot Rolled Steel 930284

TS590N/mm2 hot rolled steel showing a good balance of stretch formability and stretch flangeability has been newly developed for manufacturing high strength automotive parts. A laboratory study revealed that an introduction of a small amount of martensite in ferrite · bainite microstructure remarkably improves uniform elongation of ferrite · bainite steel giving little influence on its good localized elongation. Characteristics in ductile property of this “Tri-Phase” type steel were confirmed in press forming tests.
