Abstract

The invention relates to a method for producing an ultra high strength material with high elongation by work hardening an essentially nickel-free austenitic material and then subjecting the material to heat treatment in the temperature range between 200° C. and <1,100° C. within a period from 10 s to 10 minutes.
