**Nitronic alloys** are a type of nitrogen-strengthened austenitic stainless steel that provide exceptional mechanical strength, impressive resistance to galling, and outstanding corrosion resistance—even in harsh chloride-rich and acidic environments. **Nitronic 50** delivers nearly double the yield strength of 316 stainless steel and has enhanced pitting resistance, while **Nitronic 60** is specifically designed for superior wear and galling resistance, making both options perfect for high-stress applications.
