Nitronic 60 is an all-purpose austenitic stainless steel that exhibits excellent yield strength due to the inclusion of nitrogen in the alloy. It also maintains the superior corrosion resistance of other austenitic stainless steels. These properties make it uniquely suited to marine and chemical industries.
Nitronic is a trade name for a group of nitrogen-strengthened austenitic stainless steels. Instead of only strengthening the surface of the steel via the nitriding process, nitronic alloys incorporate nitrogen homogeneously through the entire crystal structure. This property strengthens the steel throughout rather than just on the surface. The resultant metal has the same corrosion resistance as other austenitic steels like 316 stainless steel while exhibiting up to twice the yield strength. Nitronic alloys offer a low-cost alternative for wear and galling resistance when compared to nickel and cobalt alloys.
|Application||Marine shafts, centrifugal pumps, fasteners, valve seats|
|Advantages||High temperature resistance, excellent corrosion and wear resistance, High yield strength, resistant to galling (prevents cold welding of fasteners typical of 316 or 304 stainless steel), excellent oxidation resistance, Potential alternative to nickel and cobalt alloys|
|Disdvantages||High cost compared to standard austenitic stainless steel; machining can be challenging due to work hardening|
|Lead Time||Lead time is generally a minimum of 3 days. However, this can increase depending on availability or if the parts are to be internationally manufactured.|
|Tolerances||Machining tolerances of 0.005” (0.13 mm) are achievable.|
|Wall Thickness||A minimum wall thickness of 0.03” (0.8 mm) is achievable. This can vary depending on the ratio of wall thickness to planar dimension.|
|Max Part Size||The maximum size of the part is determined by the machines available and the complexity of the part.|
Parts made via CNC machining in Nitronic 60 differ from those in other nitronic alloys due to the material’s superior galling resistance (i.e. wear caused by localized bonding and subsequent tearing of bits of material when parts slide against each other). In addition to its galling resistance, Nitronic 60 has almost double the yield strength of more common stainless steels like 316 or 18-8. Nitronic 60 also resists corrosion far better than most similar metals. These properties make it ideal for mechanical components like shafts, fasteners, or gears that experience sliding contact and need high strength while being subjected to corrosive operating environments.
