UGI® 209 Solution Annealed
UGI® 209 Solution Annealed introduction
An austenitic stainless steel with high corrosion resistance and superior mechanical performances. UGI® 209 is an austenitic stainless steel with a high yield strength designed for use in very severe corrosive environments. This grade also features excellent cryogenic properties and very high, stable magnetism.
Entirely austenitic solution annealed structure with no intercrystalline precipitation. For cold hardened products, an austenitic cold hardened structure with twin crystals.
The composition and excellent stability of the austenitic structure make UGI®209 a very amagnetic grade for different cold hardening levels and temperatures. Some indicative values are shown below.
