Common name： 201 Stainless, 201 Stainless Steel, 201 steel, 201 ss
Type 201 Stainless Steel is an austenitic chromium-nickel-manganese stainless steel which was developed to conserve nickel. Type 201 is a lower cost alternative to conventional Cr-Ni stainless steels such as 301 and 304. Nickel is replaced by additions of manganese and nitrogen. It is non-hardenable by thermal treatment, but may be cold worked to high tensile strengths. Type 201 can be substituted for Type 301 in many applications.
Chemical Composition and mechanical properties:
tensile strength σb (MPa)
yield strength σ0.2(MPa)
201 ss Plate/Sheet, 201 ss coil, 201 ss Pipe Tube, 201 ss Round Bar, 201 Flat Bar
Type 201 is essentially nonmagnetic in the annealed condition and becomes magnetic when cold worked.
201 stainless steel has the characteristics of polishing without bubble, without pinhole and some other Excellent properties.
The 201 stainless steel has similar resistance to general corrosion as the unstable 304 stainless steel
Mainly used for decoration pipe, industrial pipe, some products of light stretch. The long-term heating of 201 stainless steel in the temperature range of chromium carbide degree may affect the alloy 321 stainless steel plate and 347 in the corrosive medium. 201 Stainless steel is mainly used in high temperature applications, which require strong anti-sensitization properties of materials to prevent corrosion between grains at low temperature.
