UNS N08330
N08330 is a heat resistant nickel alloy with excellent high temperature strength, corrosion resistance, and metallurgical stability. In particular, it provides superior resistance to carburization and nitridation. Because it has a fully austenitic microstructure, it displays good workability.
Supply form with following, other form could custom producing

작업 성
The hot workability and cold workability of N08330 are similar to those of conventional austenitic stainless steels. For hot working, a starting temperature of 1230℃ and finishing temperature of 980℃ are suitable. Cold workability is similar to that of conventional austenitic stainless steels. Work hardening tends to be slightly lower. Bending, drawing, and similar working are possible.
용접성
N08330 can be welded by TIG, MIG, and shield metal arc welding in the same manner as with conventional standard austenitic stainless steels. AWS ERNiCr-3 welding electrodes are frequently used.
열 치료
Heat treatment of NAS N08330 is similar to that of conventional austenitic stainless steels. The typical heat treatment is as follows:
- Solution heat treatment: 1040~1120℃
Carbide dissolution and strain removal are performed in the above solution heat treatment.
산세
Pickling is performed with a nitric-hydrofluoric acid solution or aqua regia solution (nitric-hydrochloric acid solution) in the same manner as with standard austenitic stainless steels.
특징
N08330 is used mainly in high temperature carburizing or nitriding atmospheres. It is most suitable for application in the 815~1150℃ temperature range.
