Corrosion Resistance of Exotic Alloy XM-19 (Nitronic 50)
- Exotic Alloy XM-19 Sheets & Plates offer a corrosion profile that outperforms standard austenitic stainless in most media.
- General corrosion resistance: outperforms 316(L) and 317(L) across many chemical environments.
- Pitting and crevice resistance: PREN above 34, comparable to duplex 2205, giving better resistance than 316(L).
- Chloride SCC caution: not recommended for hot chloride ion environments, where it can be susceptible to stress corrosion cracking.
Heat Resistance of Exotic Alloy XM-19 (Nitronic 50)
Exotic Alloy XM-19 sheets and plates retain very good mechanical properties at both elevated and sub-zero temperatures. It cannot be hardened by heat treatment; strength is developed through solution annealing and, where higher strength is needed, controlled hot working. Confirm exact service limits against the governing standard and application before specifying.
Key Properties of Exotic Alloys XM-19 Sheets
Beyond corrosion and heat performance, XM-19 sheets and plates offer these additional properties.
- Roughly double the yield strength of standard 316L
- Good toughness maintained at sub-zero temperatures
- Good weldability using matched filler metal
- Non-magnetic even after cold working
