MATERIAL / APPLICATION / CONDITIONThe right alloy.
The right alloy.
The right specification.
Nitronic 60 (UNS S21800) is a nitrogen-strengthened austenitic stainless steel with elevated silicon and manganese additions. It is recognised for resistance to galling and wear in selected metal-to-metal contact applications.
Anti-galling does not mean galling-proof. Contact load, mating alloy, surface finish, lubrication and assembly practice still matter. EMG reviews specified Nitronic 60 fasteners and machined parts as an engineered assembly requirement, not a blanket replacement for conventional stainless.

PROCUREMENT REFERENCE
What to specify
Reference designations are not stock, certified equivalence or guaranteed service suitability. Final product requirements govern every quotation.
WHERE THE SPECIFICATION MATTERS
Engineered around the application
Threaded assemblies
Specified bolts, nuts and threaded components subject to repeated assembly or stainless-on-stainless contact.
Valve trim & stems
Sliding-contact parts where galling resistance is an explicit design requirement.
Pump & wear components
Shafts, pins, bushes and sleeves with controlled fits, finishes and mating-pair selection.
ENGINEERING CHECKPOINTS
Control the details that matter.
01
Galling is an assembly problem
Review thread engagement, surface finish, contact stress, lubrication and installation practice alongside the material. No alloy eliminates every seizure mechanism.
02
Do not confuse 50 and 60
Nitronic 50 and Nitronic 60 are different alloys with different UNS identifiers and performance priorities. A brand-family name is not sufficient for a purchase order.
03
Corrosion needs its own check
Wear resistance does not establish suitability for seawater, concentrated chemicals or sour service. Confirm the actual exposure and acceptance requirements.
