201 stainless steel round bar
Langsda Metal Products Co.,Ltd supply 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.
Description
201 stainless steel is an alloy that contains half the nickel and increased manganese and nitrogen of more popular steels.
Type 201&202 is an austenitic metal because it is a non-magnetic stainless steel that contains high levels of chromium and nickel and low levels of carbon.
SPECIFICATIONS
Type 201 Stainless Steel is covered by the following specifications:
ASTM A240

NO.1 | The surface finished by heat treatment and pickling or processes corresponding there to after hot rolling. | Chemical tank, pipe. |
Application
Type 201 is used to produce a range of household appliances, including sinks, cooking utensils, washing machines, windows, and doors. It is also used in automotive trim, decorative architecture, railway cars, trailers, and clamps. It is not recommended for structural outdoor applications because of its susceptibility to pitting and crevice corrosion.
