201 Stainless Steel Sheet
201 stainless steel sheet is a low-nickel, high-work hardening austenitic stainless steel alloy. it is characterized by its excellent corrosion resistance, good ductility, and high tensile strength. it has higher manganese and nitrogen content than traditional austenitic stainless steel.
It offers a cost-effective solution for applications where the use of 300 series stainless steel is not essential.

201 stainless steel contains less nickel and more manganese than other austenitic stainless steels like 304. This composition makes it less expensive, which is advantageous for applications where budget constraints are important.It has high tensile strength (515-735 MPa) and yield strength (275-380 MPa), making it suitable for structural applications and components that need to withstand significant loads.With an elongation of around 40%, 201 stainless steel can be easily formed and shaped into various products without cracking or breaking.
Properties
- Corrosion Resistance: 201 stainless steel sheet offers good corrosion resistance in most environments, but not as good as 304 or 316 stainless steel.
- Strength and Hardness: It has high tensile strength and hardness, making it suitable for applications requiring durability.
- Formability: The alloy is ductile and can be easily formed into various shapes.
- Weldability: 201 stainless steel sheets are weldable using conventional welding techniques.
- Finish: It can be polished to a mirror-like finish or have a brushed or matte surface.
