Family: Austenitic chromium-manganese stainless

## What it is

An austenitic stainless steel in which manganese and nitrogen replace part of the nickel. It costs less than 304 but has lower corrosion resistance and work-hardens faster.

## Typical uses

Cookware, appliance trim, sinks, decorative tube and indoor applications without strong corrosion.

## Machining notes

Harder to machine than 304 because it work-hardens faster. Use sharp tools, positive rake and steady feed.

## Related grades

- 304 stainless steel (1.4301): Higher-nickel standard grade with better corrosion resistance
- 430 stainless steel (1.4016): Nickel-free ferritic alternative

Equivalents are nearest matches, not identical grades. The governing standard or mill certificate decides.
