Austenitic treated steels can be additionally partitioned into two sub-gatherings, 200 arrangement and 300 arrangement:
200 series are chromium-manganese-nickel amalgams that augment the utilization of manganese and nitrogen to limit the utilization of nickel. Because of their nitrogen expansion, they have roughly half better return strength than 300 arrangement impeccable sheets of steel.
Type 201 is hardenable through cool working.
Type 202 is a universally useful hardened steel. Diminishing nickel content and expanding manganese brings about feeble consumption opposition.
