High Nitrogen Nickel Free Austenitic Stainless Steel

In the present study a high nitrogen nickel free austenitic stainless steel with 0 96 wt nitrogen was processed with fsw.

High nitrogen nickel free austenitic stainless steel.

The austenitic microstructure is obtained exclusively by adding nitrogen. 901 908 nickel free high nitrogen austenitic steels peter j. Because of this nickel free high nitrogen austenitic stainless steel nickel free γ hns has recently attracted attention as a harmless biomaterial as well as a resource saving ecomaterial. Swiss federal institute of technology eth sonneggstrasse.

In addition the high cost of nickel can be a major problem in industrial production. By combining the benefits of stable austenitic structure high strength better corrosion and wear resistance superior biocompatibility and cost effectiveness due to replace nickel by nitrogen the newly developed nickel free high nitrogen stainless steel will be a reliable substitute to the conventional medical stainless steels i e. The flow behavior of nickel free high nitrogen austenitic stainless steels is modeled and the effect of nitrogen on the flow behavior is summarized. 2 experimental the chemical composition of nick free high nitrogen austenitic stainless steels with nitrogen content of 0 82 and 0 96 is showed in table 1.

High nitrogen austenitic stainless steel is a nickel free high cr mn n steel having a wide scope in defence sector for manufacturing battle tanks by replacing the existing armour steel.
