201 Stainless Steel Supply

201 stainless steel is a low-nickel, high-manganese stainless steel that offers moderate strength, good ductility, corrosion resistance, weldability, magnetic properties, and heat resistance. It is a popular choice for various applications, including kitchen appliances, automotive trim, and industrial equipment, due to its unique properties.

201 Stainless Steel Properties

Strength: 201 stainless steel has moderate strength, making it suitable for applications that require moderate mechanical strength. It has a minimum tensile strength of 515 MPa and a minimum yield strength of 275 MPa.

Ductility: 201 stainless steel has good ductility, which means that it can be easily formed and shaped without cracking or breaking. This property makes it ideal for applications that require complex shapes or designs.

Corrosion Resistance: 201 stainless steel is known for its excellent corrosion resistance in mildly corrosive environments. It is resistant to rust and staining and is suitable for indoor and outdoor applications.

Weldability: 201 stainless steel is known for its good weldability, making it a popular choice for welding, brazing, and soldering. It can be welded using common welding techniques, such as TIG, MIG, and stick welding.

Magnetic Properties: 201 stainless steel is magnetic, which makes it suitable for applications that require magnetic properties.

Heat Resistance: 201 stainless steel has good heat resistance up to 760°C (1400°F). It can be used in high-temperature applications such as furnace parts, heat exchangers, and exhaust systems.

201 Stainless Steel Applications

201 stainless steel is a type of austenitic stainless steel that contains a combination of chromium, nickel, and manganese. While it is less corrosion-resistant than some other stainless steel grades, it still finds use in various applications. Here are some common applications of 201 stainless steel:

  1. Cookware: 201 stainless steel is used in the manufacturing of cookware such as pots, pans, and kitchen utensils due to its durability and corrosion resistance.
  2. Kitchen Sinks: Some kitchen sinks are made from 201 stainless steel due to its corrosion resistance, affordability, and ease of fabrication.
  3. Appliances: Components of household appliances, including refrigerators, dishwashers, and microwave ovens, may use 201 stainless steel for its corrosion resistance and cost-effectiveness.
  4. Automotive Trim: Certain automotive trim pieces and decorative elements on vehicles may be made from 201 stainless steel due to its aesthetic appeal and corrosion resistance.
  5. Railings and Handrails: 201 stainless steel is used in the construction of railings and handrails for stairs, balconies, and decks due to its corrosion resistance and visual appeal.
  6. Furniture: Some furniture components, especially outdoor furniture, may use 201 stainless steel for its corrosion resistance and durability.
  7. Decorative Applications: 201 stainless steel is employed in various decorative applications, such as architectural trim, signage, and ornamental elements.
  8. Tubing and Piping: Certain tubing and piping applications, especially those in less corrosive environments, may use 201 stainless steel for its cost-effectiveness.
  9. Utensils and Cutlery: Kitchen utensils, flatware, and certain types of cutlery may be made from 201 stainless steel due to its corrosion resistance and affordability.
  10. Construction: Some construction components, such as screws, bolts, and fasteners, may use 201 stainless steel for its corrosion resistance and strength.
