201/SUS201 Stainless Pipe/Tube
201 stainless steel is an austenitic chromium-nickel-manganese stainless steel, belonging to the 200 series of stainless steel. It is based on 304 stainless steel, reducing the nickel content and increasing manganese and nitrogen to reduce costs while maintaining a certain degree of corrosion resistance and formability. Due to its lower price, 201 stainless steel is often used to replace 304 stainless steel and is suitable for environments that do not require high corrosion resistance.
