ASTM A240 201 (UNS S20100) Stainless Steel Sheet
Leading 201 Stainless Steel Sheet Manufacturer in China
ASTM A240 Type 201 (UNS S20100) is the premier choice for applications demanding a reliable and economical alternative to traditional chromium-nickel stainless steels. As a highly versatile material, Type 201 stainless steel provides a robust solution for a vast range of industrial, commercial, and consumer applications.It features high tensile strength and toughness, making it suitable for structural components and parts that require durability. This grade can be readily formed, stamped, and drawn using standard fabrication techniques. While non-magnetic in the annealed state, it becomes magnetic when cold-worked.Its corrosion resistance is comparable to other 300-series steels in many mild environments.

Characteristics of 201 Stainless Steel
- Cost-Effective Alternative: Developed to conserve nickel, making it cheaper than 300-series stainless steels.
- High Strength and Work Hardening: This grade exhibits high yield and tensile strength in its annealed condition. It has a high work-hardening rate.
- Good Formability and Fabricability: High strength while remaining formable, allowing fabrication through roll forming and brake bending.
- Good Weldability: Type 201 stainless steel can be welded using standard fusion and resistance methods, with Type 201 filler materials recommended.
- Corrosion Resistance: Resists mild corrosion, similar to Type 301, and often replaces Type 304 in less demanding uses.
- Versatile Applications: Type 201’s strength, formability, and affordability make it an ideal choice for a wide range of applications.
- Excellent Toughness at Low Temperatures: Type 201 remains tough in freezing conditions, making it ideal for cold environments and impact-resistant applications.
- Austenitic and Primarily Non-Magnetic: It is non-magnetic in the annealed condition. It becomes slightly magnetic when it undergoes cold working processes.
