Nitronic 60 Stainless Steel Bar
UNS S21800, commercially known as Nitronic® 60, is a high-performance austenitic stainless steel engineered to deliver exceptional mechanical strength, wear resistance, and corrosion protection-far surpassing conventional grades like Type 304 and 316. Originally developed for high-temperature applications, Nitronic 60 excels in extreme wear, galling, and oxidation resistance, making it a preferred choice for demanding industrial, aerospace, and energy applications.
Key Features & Benefits
- Superior Strength – Offers nearly double the yield strength of Type 316 stainless steel, even in the annealed condition.
- Outstanding Wear & Galling Resistance – Enhanced by silicon and manganese additions, reducing friction and material degradation in moving parts.
- High-Temperature Performance – Maintains structural integrity up to 1800°F (982°C), with oxidation resistance comparable to Alloy 309.
- Good Corrosion Resistance – Performs well in mildly corrosive environments, though not as resistant as super-austenitic or nickel alloys.
- Non-Magnetic in Annealed State – Unlike some austenitic steels, it remains non-magnetic unless heavily cold-worked.

Application
Nitronic 60 is widely used in industries where wear resistance, high strength, and moderate corrosion resistance are critical:
- Valve Components – Valve seats, stems, and trim for oil & gas, chemical processing
- Aerospace & Defense – Aircraft bearings, landing gear components, fasteners
- Marine & Offshore – Shafts, couplings, and pump components exposed to seawater
- Industrial Machinery – Gears, bushings, and wear plates in high-friction environments
- High-Temperature Equipment – Furnace parts, heat exchangers, and exhaust systems
Fabrication & Processing
Cold Working
Cold rolling or drawing can further increase strength, but does not improve anti-galling properties.
Heavy cold working may induce slight magnetism.
Machining & Welding
Machining: More challenging than standard austenitic grades; requires rigid setups and carbide tooling.
Welding: Compatible with TIG (GTAW), MIG (GMAW), and SMAW methods. Post-weld heat treatment is typically unnecessary.
Heat Treatment
Annealing: Performed at 1900–2050°F (1038–1121°C) followed by rapid cooling to optimize corrosion resistance and ductility.
