Introducing austenitic stainless steels with excellent deep drawability and punch stretchability.
Those that have been subjected to solution treatment are essentially non-magnetic and cannot be hardened by heat treatment.
These austenitic stainless steels exhibit a wide range of mechanical properties by cold forming, and may even exhibit slight magnetic properties.
In addition, annealing is performed by rapidly cooling from a high temperature, resulting in maximum softness, ductility, and corrosion resistance.
