Nitronic 60 Stainless Steel Bar (S21800)
Arch Metals supplies Nitronic 60 stainless steel bar from Dallas, Texas, to valve, pump and equipment manufacturers across Texas and the surrounding states. Nitronic 60, UNS S21800, is an austenitic stainless steel known for outstanding resistance to galling and wear, with corrosion resistance comparable to 304 and about twice its yield strength. We supply bar to ASTM A276/A479 and AMS 5848 with certified material and saw cutting to length. Request a quote and we’ll confirm sizes and availability.
Nitronic 60 Stainless Steel Forms
- Round bar, annealed
- Bar for valve stems, pins and bushings
Size availability changes with mill supply. Send us your sizes through our quote request form and we’ll confirm stock, lead time and pricing.
Nitronic 60 Conditions and Specifications
- Annealed bar (ASTM A276, ASTM A479, AMS 5848): solution annealed. Silicon and manganese additions give its galling resistance without heat treatment.
- Equivalent designations (UNS S21800): sometimes listed as 218 stainless.

Typical Properties of Annealed Nitronic 60
- Ultimate tensile strength: about 103 ksi (710 MPa)
- Yield strength: about 60 ksi (414 MPa)
- Elongation: about 60%
- Density: 0.276 lb/in³ (7.62 g/cm³)
- Chemistry: about 17% chromium, 8.5% nickel, 8% manganese and 4% silicon, with nitrogen
These are typical values for annealed bar. Guaranteed minimums vary by specification, condition and size, so check the governing spec or your mill cert for design values.
Why Engineers Choose Nitronic 60
Most stainless steels gall badly when they slide against each other. Nitronic 60 is one of the few that can run against itself and other stainless steels without seizing, which often lets designers drop costly hard coatings or cobalt alloys. Its corrosion resistance is similar to 304 stainless steel. For better seawater resistance, see Nitronic 50. Common uses for Nitronic 60 include:
- Valve stems, seats and trim
- Pins, bushings and wear rings
- Fasteners that must not gall
- Pump and marine components
Nitronic 60 Stainless Steel FAQs
What makes Nitronic 60 galling resistant?
Its silicon and manganese content changes how the surface work-hardens and deforms, so mating surfaces don’t cold-weld and tear the way 304 or 316 do.
Can Nitronic 60 run against itself?
Yes. Nitronic 60 against Nitronic 60 is one of the few stainless-on-stainless pairs that resists galling under load.
How does Nitronic 60 compare with Nitronic 50?
Nitronic 60 is chosen for galling and wear resistance. Nitronic 50 is chosen for strength and corrosion resistance, especially in seawater.
