Forms we supply
Nitronic in every common form.
Nitronic 50 (XM-19) pairs corrosion resistance better than 316L with roughly twice its yield strength; Nitronic 60 is the stainless steel of choice where metal-to-metal galling and wear are the problem.
Corrosion & temperature resistance
Nitronic 50 resists pitting, crevice corrosion and seawater better than 316/317; Nitronic 60 offers corrosion resistance between 304 and 316 with outstanding galling resistance.
Applications
Marine shafting, pump shafts, valve stems and seats, fasteners, wear plates and chemical process components.
