NSSC Austenitic
The austenitic type stainless steels, as far as worked with solid solution heat treatment, are non-magnetic and nonhardenable by heat treatment, while they exhibit a wide range of mechanical properties and become slightly magnetic when cold worked.
And especially, they can exhibit the maximum softness, elongation and corrosion resistance in its annealed state; that is rapid cooling from high temperatures.
