Performance
An austenitic grade that replaces part of the nickel with manganese and nitrogen; its room-temperature strength is close to 304, but corrosion resistance is clearly weaker, especially against chlorides and moisture.
Use cases
Used for indoor decorative tubes, handrails, low-end cookware and non-critical parts in dry environments; not for coastal, outdoor or acid/alkali contact.
Characteristics
Low cost and formable by cold work, weakly magnetic (slight magnetism after cold work); average weldability with reduced corrosion resistance near the weld.
