Grade dossier
Nitronic 60 Stainless Steel for Galling and Wear Resistance
An austenitic stainless grade engineered for resistance to galling, fretting and adhesive wear in fasteners and moving components.
Identity before substitution
Define the grade, product and condition together
A familiar grade name is not a complete purchase specification. Product form, controlling standard, dimensions, condition, finish, certification and service environment determine whether the delivered material is suitable.
Composition control
ASTM A240/A240M flat-product chemistry
Limits are not heat analysis targets
The table summarizes grade limits commonly used for plate, sheet and strip. Pipe, tube, bar, forgings and cast products can be governed by different specifications. Always place the product standard and edition on the purchase order.
| C | 0.10 max |
|---|---|
| Mn | 7.00-9.00 |
| Si | 3.50-4.50 |
| P | 0.060 max |
| S | 0.030 max |
| Cr | 16.00-18.00 |
| Ni | 8.00-9.00 |
| N | 0.08-0.18 |
Properties with context
Minimums, typical indicators and delivered condition
Specified annealed flat-product values
| Bar tensile strength | 655 MPa min |
|---|---|
| Bar 0.2% yield strength | 345 MPa min |
| Elongation | 35% min |
| Hardness | 241 HBW max |
Selection indicators
| Density | about 7.61 g/cm3 |
|---|---|
| Primary benefit | Galling, fretting and adhesive-wear resistance |
| Corrosion position | Typically between 304 and 316; verify service |
| Work hardening | High; machining requires rigid practice |
Values depend on product form, thickness, test orientation, condition and governing edition. Use the mill test certificate and the purchase specification for acceptance, not a web table alone.
Selection boundary
Where Nitronic 60 belongs and where to escalate
Grade selection is an environmental decision, not a popularity contest. Review the complete medium, temperature, geometry, fabrication, cleaning and inspection requirements.
Good reasons to evaluate it
Fasteners and threaded assemblies
Pins, bushings and wear rails
Pump components and valve trim
Roller-bearing and sliding-contact parts
Reasons to stop and review
Assuming anti-galling means dry running is always safe
Using the grade as a universal corrosion upgrade
Ordering without bar condition and property range
Applying sheet values to finished fasteners
Fabrication route
Protect properties through cutting, forming and welding
Specify S21800, form, condition and final hardness.
Use rigid machining setups and positive cutting action.
Evaluate mating material, surface finish and lubricant together.
Qualify welding where wear surfaces are affected.
Supply definition
Product form changes the applicable requirements
Do not send an RFQ that names only the grade. State form, governing standard, dimensions, tolerances, finish, edge or end condition, quantity, certification and inspection.
Bar and shapes to ASTM A276/A479
Fastener stock under applicable specifications
Pins, bushings and machined wear parts
Special plate or weld products only when explicitly available
Certificate checkpoint
Request heat identity, chemical analysis, mechanical results and compliance to the exact product specification. Add PMI, corrosion testing or supplementary examination only when the application requires it.

Procurement FAQ
Questions to close before placing the order
Is Nitronic 60 stainless steel magnetic?
Magnetic response depends on microstructure and delivered condition.
Can Nitronic 60 replace another grade?
Only after checking the governing standard, composition, mechanical properties, corrosion exposure, fabrication route and certification. A commercial name is not a substitution approval.
Does the table apply to every product form?
Not automatically. The values shown use flat-product requirements as a reference. Other forms can use different product standards, dimensions and tests.
What should a Nitronic 60 RFQ include?
Product form, standard and edition, UNS or EN designation, dimensions, tolerances, finish, quantity, service, fabrication, certificate and inspection requirements.
