Nitronic 60 Round Bar
Nitronic 60 Round Bar Manufacturer & Supplier
Emirerri Steel offers premium-quality Nitronic 60 Round Bar, an austenitic stainless steel known for its outstanding resistance to wear, galling, and fretting. Also known as UNS S21800, Nitronic 60 is engineered to perform exceptionally under metal-to-metal contact and high-stress environments where conventional stainless steels often fail.
Its unique composition of silicon and manganese enhances its galling resistance, making it superior to stainless steels like 304 and 316. Nitronic 60 combines excellent oxidation resistance, high strength, and superior corrosion resistance, even at elevated temperatures.
Key Features
Exceptional Galling Resistance: Superior to 304 and 316 in wear and frictional resistance.
High Strength: Retains high mechanical strength at both ambient and elevated temperatures.
Excellent Corrosion Resistance: Performs well in oxidizing and mild reducing environments.
Good High-Temperature Stability: Suitable for service up to 1800°F (982°C).
Non-Magnetic in Annealed Condition: Retains non-magnetic properties even after cold working.
Low Maintenance Alloy: Excellent durability reduces maintenance and replacement costs.
