Performance
Higher nickel and manganese than 201 give slightly better corrosion resistance, but still clearly weaker than 304; a low-nickel economical austenitic grade.
Use cases
Indoor decoration, utensils and architectural interiors in non-severe environments; not recommended for food, medical or coastal service.
Characteristics
Better formability and weldability than 201, and a 304-like appearance that makes it a common low-cost visual substitute.
