Frequently asked questions
When do you spec Nitronic 60 vs 50?
60 for anti-galling — valve stems, wear surfaces, weapon mechanisms. 50 for corrosion + moderate strength — general marine and oilfield service where standard stainless isn't enough.
Is Nitronic difficult to machine?
About as difficult as 316 stainless — sharp tooling, moderate feeds. Work hardens if abused. Coated carbide standard.
