What is Nitronic 60 Annealed?
Nitronic 60 Annealed is Nitronic 60 in the Annealed temper — pick for sheet, strip, screen wire and formed parts where cold formability and weldability matter more than strength. Nitronic 60 Annealed has a yield strength of 448 MPa (65 ksi) and a tensile strength of 745 MPa (108 ksi) — stronger than 68% of stainless steel grades. Elongation at break is 55% and the elastic modulus is 196 GPa (28.4 Msi). Nitronic 60 Annealed has a density of 7.63 g/cm³ (0.276 lb/in³), lighter than 96% of stainless steel grades. It melts at 1,343°C (2,449 °F). Solution Annealed is the default condition FabDigit quotes; Annealed is available on request or by drawing note.

Other Nitronic 60 tempers and conditions
Nitronic 60 is also supplied in 4 other conditions. The full side-by-side table is on the Nitronic 60 overview.
- Solution AnnealedDefaultDefault stocked condition for bar, plate and forgings: maximum ductility and corrosion resistance with ~2× the yield strength of 304 and full galling resistance.414 MPa yield · 210 HB
- Cold Worked HSUse where maximum strength and wear resistance are needed (fasteners, springs, high-load pins); ductility and toughness are reduced.1,000 MPa yield · 35 HRC
- Cold DrawnChoose for precision-diameter bar, valve stems and pins needing ~700 MPa yield with good surface finish and straightness.760 MPa yield · 30 HRC
- AnnealedPick for sheet, strip, screen wire and formed parts where cold formability and weldability matter more than strength.448 MPa yield · 215 HB
Working with Nitronic 60 Annealed
Is Nitronic 60 easy to machine?
Gummy and strongly work-hardening — run 30–50 % of 304 speeds with rigid setups, positive-rake sharp carbide, heavy constant feed to stay under the hardened skin, and copious high-lubricity coolant.
Can Nitronic 60 be welded?
Readily welded by GTAW/GMAW/SMAW with matching Nitronic 60 filler (or 209/240 types); no preheat or post-weld heat treatment needed, keep interpass temperature low and use low heat input to limit distortion.
Can Nitronic 60 be formed, bent or molded?
Cold forms and bends well when allowance is made for the high work-hardening rate (higher press loads, generous bend radii, intermediate anneals for severe draws); hot works at 1010–1200 °C.
What surface finishes work on Nitronic 60?
Passivate per ASTM A967 or electropolish for best corrosion performance; takes a good mechanical polish, and no coating is needed for anti-galling function — do not attempt anodizing.
Nitronic 60 chemical composition (wt %)
Limits by weight percent from the governing specification, written the way the spec states them — a single maximum for impurities, a range for alloying elements, and the base element as balance. Nominal is the typical mid-range value.

Nitronic 60 Annealed — frequently asked
What is Nitronic 60 Annealed used for?
Nitronic 60 Annealed is typically used for anti-galling fasteners and threaded parts, valve stems, seats and trim, bushings, pins and wear pads, pump and mixer shafts, screens and wear plates and marine deck hardware. In short: high-hardness galling resistant.
What is the yield strength of Nitronic 60 Annealed?
Nitronic 60 Annealed has a typical yield strength of 448 MPa (65 ksi) and a tensile strength of 745 MPa (108 ksi) — stronger than 68% of stainless steel grades. Strength varies by condition: see the 5 listed tempers.
Is Nitronic 60 Annealed easy to machine?
Not especially — machinability is rated poor (28/100, worse than 80% of stainless steel grades). Gummy and strongly work-hardening — run 30–50 % of 304 speeds with rigid setups, positive-rake sharp carbide, heavy constant feed to stay under the hardened skin, and copious high-lubricity coolant.
Can Nitronic 60 Annealed be welded?
Yes — weldability is rated very good (72/100). Readily welded by GTAW/GMAW/SMAW with matching Nitronic 60 filler (or 209/240 types); no preheat or post-weld heat treatment needed, keep interpass temperature low and use low heat input to limit distortion.

What is the maximum service temperature of Nitronic 60 Annealed?
Nitronic 60 Annealed is rated for continuous use to about 870°C (1,598 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
