# 2205 duplex stainless steel equivalents

2205 duplex stainless steel is nearest to EN 1.4462 (X2CrNiMoN22-5-3), JIS SUS329J3L and China GB 022Cr23Ni5Mo3N. These are nearest equivalents, not identical grades: the governing standard or mill certificate decides.

| System | Designation |
|---|---|
| AISI / ASTM / SAE | 2205 duplex |
| EN steel name | X2CrNiMoN22-5-3 |
| EN steel number | 1.4462 |
| JIS | SUS329J3L |
| China GB | 022Cr23Ni5Mo3N |

Family: Duplex (austenitic-ferritic) stainless

## What it is

A duplex stainless steel with a mixed austenite and ferrite structure. It is considerably stronger than 304 and 316 and much more resistant to chloride stress-corrosion cracking.

## Typical uses

Oil and gas and offshore equipment, chemical tanks, desalination plant, heat exchangers and pulp and paper equipment.

## Machining notes

Harder to machine than 316. Use rigid setups, sharp carbide, reduced speeds and constant feed.

## Related grades

- 316L stainless steel (1.4404): Austenitic grade with molybdenum
- 316 stainless steel (1.4401): Standard molybdenum grade

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