Type 201 stainless steel Chemical composition

Type 201 stainless steel is an Austenitic Standard grade Stainless Steel. It is commonly called Type 201 Chromium-Manganese-Nickel steel.

Type 201 stainless steel Chemical composition ：
It is composed of (in weight percentage) 0.15% Carbon (C), 5.5-7.5% Manganese (Mn), 1.00% Silicon (Si), 16.0-18.0% Chromium (Cr), 3.5-5.5% Nickel (Ni), 0.06% Phosphorus (P), 0.03% Sulfur (S), 0.25% Nitrogen (N), and the base metal Iron (Fe). Other designations of AISI Type 201 stainless steel include UNS S20100 and AISI 201.

Type 201 stainless steel is part of the 200 series of austenitic stainless steels. Originally developed to conserve nickel, this family of stainless steels is characterized by low-nickel content.

Type 201 stainless steel can substitute for type 301stainless steel in many applications, but is less corrosion resistant than its counterpart, particularly in chemical environments.

Type 201 stainless steel 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.
