This austenitic chromium-nickel-manganese stainless alloy was developed mid-century to conserve nickel. Alloy 201 can
be used as an alternative to alloy 301 in some tempered applications. Because of the relatively high yield strength in the annealed condition, the use of alloy 201 is limited in this condition. Alloy 201 is generally used in the tempered condition particularly for springs and fasteners.
