- High nitrogen steels (HNS) are a new class of high alloy martensitic, austenitic or duplex grades with up to 0.9 mass% of N in solid solution.
- They are applied e.g. to stainless tools and bearings, in chemical engineering and for high strength non-magnetic components.
- HNS is not only tough but also has good strength. In addition to being nonmagnetic as well as corrosion resistant, the HNS cost is about 40% less compared to Rolled Homogenous Armour Steel (RHA).
- This material has potential for a number of defence and civil applications like armouring, mine trawls, oil industries etc.
