201 Stainless Steel Data Sheet

Type 201 is a lower cost alternative to conventional cr ni stainless steels such as 301 and 304.

201 stainless steel data sheet. This alloy is non magnetic in the annealed condition but becomes magnetic when cold worked. To date they have traditionally not proved very popular outside the usa. Nickel is replaced by additions of manganese and nitrogen. Type 201 stainless steel is an austenitic chromium nickel manganese stainless steel which was developed to conserve nickel.

Type 201 stainless steel is unique as it was created in response to soaring nickel prices. An austenitic non magnetic stainless steel 201 has the following composition. Composition range per astm a240 element ati 201 hp ati 201l hp carbon 0 15 max 0 03 max. It contains higher amounts of manganese 5 5 7 5 and nitrogen and lower amounts of nickel than type 304 steel.

Type 201 is an austenitic chromium nickel manganese stainless steel that was developed originally to conserve nickel. It provides properties similar to type 301 and can be used in most applications for type 301. Type 201 can substitute for type 301 in many applications but it s less resistant to corrosion than its counterpart particularly in chemical environments. Originally developed to conserve nickel this family of stainless steels is characterized by low nickel content.

It provides properties similar to type 301 and can be used in most applications for type 301. 200 series stainless steels are not new in fact they have been around for many years. Type 201 austenitic stainless steel has been available for over 50 years and has gained acceptance in a number of applications. This alloy is non magnetic in the annealed condition but becomes magnetic when cold worked.

In the type 201 composition manganese and nitrogen are partially substituted for nickel. Without as much nickel it is not as effective at preventing corrosion. The higher levels of manganese help make type 201 one of the strongest types of stainless steel banding. This means that it is cheaper but it also has much lower nickel content.

It is chromium 16 18 and nickel 3 5 5 5. Compared to the 300 series alloys the lower nickel 200 series alloys offer an economical way to obtain superior mechanical properties. Description type 201 is an austenitic chromium nickel manganese stainless steel that was developed in the 1950 s due to worldwide nickel shortages. However since they have a much lower nickel content than 300 series austentics the very high nickel price over recent years has led to significantly more interest.
