High Nitrogen Stainless Steel Composition

High nitrogen stainless steel hnss is a new kind of stainless steel that uses nitrogen to replace the expensive nickel.

High nitrogen stainless steel composition. Nitrogen in steel rebar. This articles explores the possibility of the use of martensitic high nitrogen stainless steels for cryotechnic bearings for aerospace applications where requirements stipulate that no crack initiation can be tolerated. The concurrent presence of nitrogen and molybdenum has a synergistic effect on increasing resistance against both pitting and crevice corrosion. In addition to the cost advantage due to the highly corrosion resistant properties in distilled water nacl solution and hcl solution 2 high nitrogen stainless steel has a widely application prospect in the bridges platforms and other offshore constructions.

Three nitrogen rich welding wires with nitrogen content of 0 15 0 6 and 0 9 for high nitrogen stainless steel welding were developed by a modified schaeffler diagram and equilibrium phase diagram calculation. Martensitic high nitrogen stainless steels are particularly interesting because they typically exhibit high strength and ductility good corrosion resistance and reduced grain boundary sensitization. Furthermore it is believed that a new pren formula is required for high nitrogen stainless steels containing molybdenum and manganese.
