2205
2205 is a duplex stainless steel.

Where 2205 fits
Why 2205 is special
Its mixed structure gives roughly twice the strength of ordinary stainless steel, so a vessel wall can be thinner and the whole structure lighter.

Strength 0.50, confidence "high".
Technology & computing
Alloy 2205 has a roughly balanced austenitic-ferritic microstructure, giving higher yield strength and better stress corrosion cracking resistance than 300-series grades.
