LOW NI CONTENT AUSTENITIC STAINLESS STEEL WITH HIGH STRENGTH / DUCTILITY PROPERTIES

Austenitic Stainless Steel alloy compositions are provided with reduced Ni content. These alloys, combined with a process that includes a martensite thermomechanical treatment with a thickness reduction preferably higher than 65%, provides a new generation of Advanced High Strength Steels with combi...

Beschreibung
Zusammenfassung:	Austenitic Stainless Steel alloy compositions are provided with reduced Ni content. These alloys, combined with a process that includes a martensite thermomechanical treatment with a thickness reduction preferably higher than 65%, provides a new generation of Advanced High Strength Steels with combination of tensile strength and total elongation in the range of 1000 MPa/35-55% to 1350 MPa/25-45% and good formability and weldability properties, which are useful in the manufacture of many products, particularly in the car industry.
