Nitronic 50 
Characteristic

Nitronic 50 stainless steel has a perfect combination of corrosion resistance and strength that no other commercial material has. The corrosion resistance of this austenitic stainless steel is better than that of alloy 316, 316L, 317 and 317L, and the yield strength at room temperature is about twice that of these alloys. In addition, Nitronic 50 has excellent mechanical properties at high temperature and low temperature, which is different from most austenitic stainless steel.

Nitronic 50 also does not have magnetism at low temperatures.

The yield strength of high strength (HS) Nitronic 50 is about three times that of 316 stainless steel.


Nitronic 50 application area:

It is widely used in marine, nuclear power, chemical industry and oil and gas industry.
