Austenitic chromium-nickel stainless steel alloyed with nitrogen and rare earth metals for superior high-temperature performance.
Exceptional oxidation resistance at temperatures up to 1150°C (2100°F), especially under cyclic heating conditions.
High creep strength and structural stability for reliable service in demanding thermal environments.
Good weldability and formability with excellent resistance to combustion gases and carburizing atmospheres
254SMO stainless steel round bar is a super austenitic stainless steel with high molybdenum and nitrogen content, designed for extreme corrosion resistance in aggressive environments.
It performs exceptionally well in seawater, chloride-rich conditions, and chemical processing systems where standard stainless steels fail.
Key Features
- Outstanding resistance to pitting and crevice corrosion
- Excellent performance in seawater environments
- High resistance to stress corrosion cracking
- Good weldability and fabrication properties
- Long service life in aggressive conditions
