Nitronic is the trade name for a collection of nitrogen-resistant stainless steel. They are austenitic stainless steel.

Histori
Nitronic alloys developed by Armco Steel. The first of these alloys, Nitronic 40, was introduced in 1961. Since 2000, the trademark has been owned by AK Steel, a replacement for Armco Steel. Electralloy is a licensed manufacturer in North America for a wide range of Nitronic products.
The Nitronic name is due to the addition of nitrogen to the alloy, which increases the strength internally rather than nitrided on the surface because some of the steel is treated. Nitrogen is homogeneous throughout the material. The nitronic material has about twice the yield strength of 304L and 316L.

Using today
Nitronic 30 is used to lighten transportation vehicles. Buses and trains benefit from a high strength and weight ratio for energy savings, which means less steel is used for applications. Nitronic 40 is used in the aerospace industry as a hydraulic tube. Nitronik 40 has excellent performance characteristics both at ultralow temperature, which offers "design excellence" compared to comparable alloys. Nitronic 50 is used in marine environments including boat shafting and solid rigging rods. Nitronic 60 and the like Gall-Tough "are specifically developed to have superior resistance to galling and metal to metal wear". Galling is a form of wear caused by the adhesion between shear surfaces.
Composition
Nitronic alloys have a very varied composition, but they are all dominated by iron, chromium, manganese and nitrogen.
