The major differences between 202 and 304 stainless steels are in the nickel and chromium contents.
Type 201 have high tensile strengths.201 is a lower cost alternative to conventional Cr-Ni stainless steel such as 301, 304. Type 201 is essentially nonmagnetic in the annealed condition and becomes magnetic when cold worked.

无磁不锈钢具有的特殊性质使得磁力线可以穿过，因而在某些微波器件中具有重要的应用，其在脉冲磁场下产生的涡流损耗相对于铜或者其他金属要小一些，这是由于无磁不锈钢的电导率小于铜。
