Definitions
- the steel according to the invention should be free of precipitation, since precipitation has a negative impact on toughness and corrosion resistance.
- the carbon content in particular is limited to 0.50%.
- the copper content is deliberately added.
- a special feature of the invention is that due to the high nitrogen content, the work hardening rate is higher than with other super austenites in order to be able to achieve tensile strengths (R m of 2000 MPa). This makes it possible as the last production step by cold rolling or other cold forming processes with high forming rates achieve strain hardening.
