High Nitrogen Nickel Free Austenitic Stainless Steel

The flow behavior of nickel free high nitrogen austenitic stainless steels is modeled and the effect of nitrogen on the flow behavior is summarized.

High nitrogen nickel free austenitic stainless steel. The austenitic microstructure is obtained exclusively by adding nitrogen. Swiss federal institute of technology eth sonneggstrasse. Austenitic stainless steel 0 4 n are becoming an important engineering material with combination of strength toughness and wear resistance 1. 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.

Speidel institute of metallurgy. 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. The microstructural evolution mechanical and corrosion properties were studied to reveal the microstructure and properties of friction stir welded hnas. 1996 thepaper presents the philosophy of the developmentand.

In the present study a high nitrogen nickel free austenitic stainless steel with 0 96 wt nitrogen was processed with fsw. In addition the high cost of nickel can be a major problem in industrial production. 1995 accepted in final form on january 18. Besides being nickel free the steel is further characterized by an excellent corrosion resistance the absence of.
