Nickel-based alloy steel Alloy 31

Nickel-based alloy steel Alloy 31
Equal material :N08031,1.4562
Alloy 31 is a nitrogen iron nickel chrome molybdenum alloy, face-centered cubic lattice structure, 0.2% of the nitrogen content in the stable austenite phase, reduce the tendency of the intermetallic phase precipitates out. Performance between super austenitic stainless steel and nickel base alloy. Mainly is suitable for application in the chemical and petroleum chemical industry, environmental engineering and industrial fields such as oil and gas production.
