Working with Nitronic 60 Solution 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.

What is Nitronic 60 Solution Annealed used for?
Nitronic 60 Solution 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 Solution Annealed?
Nitronic 60 Solution Annealed has a typical yield strength of 414 MPa (60 ksi) and a tensile strength of 717 MPa (104 ksi) — stronger than 61% of stainless steel grades. Strength varies by condition: see the 5 listed tempers.
Is Nitronic 60 Solution 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 Solution 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.
