Duplex compared with 316L and C45
Typical or minimum values per EN standards, for orientation.
| Material | Yield strength | Corrosion resistance | Typical use |
|---|---|---|---|
| Duplex 1.4462 | ≥ 450 MPa | Superior | Offshore, chemical, extreme environments |
| AISI 316L / 1.4404 | ≥ 200 MPa | Excellent | Marine, food, medical, outdoor |
| C45 E+C steel | ≥ 490 MPa | Low — zinc plated | Industrial, rail, heavy duty |
Why so few slides are made in Duplex
Duplex stainless steel is harder to machine and form than 316L, so most manufacturers do not offer it. FEDS manufactures Duplex slides in its own facility, combining the strength needed for heavy loads with the corrosion resistance required offshore.
Environments
- Offshore platforms and marine equipment
- Chemical and process plants
- Desalination and water treatment
- Defence-related and extreme-environment applications
Frequently Asked Questions
Is Duplex better than 316L?
Duplex 1.4462 has more than twice the yield strength of 316L and better resistance to pitting and stress corrosion cracking, which makes it the better choice for heavy loads in aggressive environments.
Is 1.4462 the same as 2205?
Yes — 1.4462 is the European designation of the duplex grade commonly known as 2205.
