It was developed mid century to conserve nickel and it is used as an alternative to type 301 in some tempered applications. Because of 201â??s relatively high yield strength in the annealed condition, use of 201 is limited. Type 201 is generally used in the tempered condition particularly for springs and fasteners. 201 Stainless will retain a comparable ductility to 301 even with the higher yield strength. Alloy 204CU is a chromium-magnesium austenitic stainless steel with an addition of 2-4% copper and nitrogen of 0.05-0.25%. Due to the addition of copper the alloy has better formability than 201 and 304. The copper improves corrosion and resistance to stress corrosion cracking in certain media. 204CU bridges the cost-property gap between 200 and 300 series stainless. Alloy 204CU is slightly after cold working but can be minimized. Type 301 is an austenitic stainless steel capable of attaining high strengths and ductility by cold working. It is not hardenable by heat treatment. Type 301 is non-magnetic in the annealed condition and becomes increasingly magnetic with cold working. It is preferable over types 302 and 304 in the tempered condition because the higher elongations (which are attainable at a given strength level) facilitate fabrication. Type 302 is not hardenable by heat treatment and in non-magnetic in the annealed condition. It becomes increasingly magnetic with cold working. If carbide precipitation is an issue 304 may be a better choice with its lower carbon content.
