Conclusion

With the stipulated amount (10–15%) of martensitic phase, smaller ferrite grain size, and a smaller amount of extracted nonmetallic inclusions we obtain the optimal combination of strength and technological ductility of cold rolled sheet steels. This is a substantiation of the technological ways of ensuring further improvement of stampability of low alloy steels with increased strength.
