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. Nickel is replaced by additions of manganese and nitrogen. It is non-hardenable by thermal treatment, but may be cold worked to high tensile strengths. Type 201 is essentially nonmagnetic in the annealed condition and becomes magnetic when cold worked. Type 201 can be substituted for Type 301 in many applications.
201 stainless steel is a type of austenitic stainless steel, a category known for its excellent formability and corrosion resistance. It is composed of chromium, nickel, and manganese, with the addition of nitrogen to enhance its strength. While 201 stainless steel is not as corrosion-resistant as some other grades, such as 304 or 316, it offers distinct advantages in terms of cost and performance for certain applications.
Composition:
- Chromium: 16-18%
- Nickel: 3.5-5.5%
- Manganese: 5.5-7.5%
- Nitrogen: 0.25%
201 stainless steel's composition provides a balance of elements that contribute to its corrosion resistance, strength, and formability. The addition of manganese enhances its durability, making it suitable for various environments.
Properties:
- Corrosion Resistance: Moderate
- Formability: Excellent
- Strength: Moderate
- Magnetic Properties: Yes
The moderate corrosion resistance of 201 stainless steel makes it suitable for indoor and mild outdoor environments. Its excellent formability allows for various fabrication processes, while its moderate strength ensures structural integrity in different applications. Additionally, its magnetic properties make it easy to identify and separate in recycling processes.
201 stainless steel is commonly used in the manufacturing of kitchen appliances such as sinks, cookware, and utensils. Its corrosion resistance and formability make it an ideal choice for these applications, ensuring longevity and ease of fabrication.
