Alloy 31 Nickel base steel

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 andnickel 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.

Alloy 31 Nickel base steel similar material are:UNS N08031,W.Nr.1.4562,X1NiCrMoCu32-28-7

Alloy 31 usually used in the following industries :
FGD systems
Pulp and Paper Industry
Fine chemical synthesis industry
Phosphoric acid production
Synthetic organic acids and esters
Recycling waste sulfuric acid
Seawater or brine heat exchanger
High pressure acid filtration technology ore processing laterite
Oil production and refining
Pickling plant (H2SO4)
Sulfuric acid condenser
Evaporation and crystallization of salt
Sour gas environments (comply with NACE Standard MR0175, reach Class VI)
