Nitronic 50 Stainless Steel Bar (XM-19)
Arch Metals supplies Nitronic 50 stainless steel bar from Dallas, Texas, for marine, oil and gas, and aerospace customers across Texas and the surrounding states. Nitronic 50, ASTM A276/A479 Type XM-19, combines corrosion resistance better than 316 with roughly twice its yield strength. We supply annealed and high-strength bar, including AMS 5764, with certified material and saw cutting to length. Request a quote and we’ll confirm sizes and availability.

- Round bar, annealed
- High-strength (HS) bar on request
- Shafting-quality bar on request
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 50 Conditions and Specifications
- Annealed bar (ASTM A276, ASTM A479 Type XM-19, AMS 5764): solution annealed for maximum corrosion resistance and ductility.
- High-strength (HS) bar (ASTM A479 XM-19): hot rolled or warm worked for higher yield strength, commonly used for marine shafting.
- Equivalent designations (UNS S20910): also known as 22-13-5 stainless.

Typical Properties of Annealed Nitronic 50
- Ultimate tensile strength: about 115 ksi (795 MPa)
- Yield strength: about 60 ksi (414 MPa); high-strength bar is higher
- Elongation: about 40%
- Density: 0.285 lb/in³ (7.88 g/cm³)
- Chemistry: about 22% chromium, 13% nickel and 5% manganese, with molybdenum, nitrogen, niobium and vanadium
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 50
Nitronic 50 resists pitting and crevice corrosion better than 316 stainless steel, especially in seawater, while offering about twice the yield strength. It stays non-magnetic after cold work and keeps good toughness at low temperatures. When galling is the main concern, look at Nitronic 60. Common uses for Nitronic 50 include:
- Marine propeller shafts and boat hardware
- Pump shafts and valve stems
- Oil and gas and chemical processing equipment
- Fasteners in corrosive service
Nitronic 50 Stainless Steel FAQs
Is Nitronic 50 better than 316 stainless steel?
For strength and seawater corrosion resistance, yes. Nitronic 50 has roughly twice the yield strength of 316 and better pitting and crevice corrosion resistance, at a higher cost.
What is Nitronic 50 HS?
HS means high strength. The bar is processed to raise its yield strength well above the annealed level, which is useful for shafting.
Is Nitronic 50 magnetic?
No. It stays non-magnetic even after cold working.
