1. Brief Introduction for Alloy 31

Alloy 31 is an iron-nickel-chromium-molybdenum alloy with nitrogen addition. It has a pitting resistance in high chloride environments between those of super-austenitic stainless steels and nickel alloys. The alloy has very good corrosion resistance in mixed acid and high chloride environments. The material is approved in ISO 15156/ NACE MR0175 to test level VI for sour gas service.

Applications:
Chemical, food, pharmaceutical and plastics industries, heat exchangers, mixing tanks, pickling equipment, synthetic rubber manufacturing equipment, pumps, valves and piping.

Chemical composition:

Physical properties:

Alloy 31 minimum mechanical properties in the room temperature:

2. Alloy 31 flange delivery time:

• If the items are available in stock, we take 2 days from the date of receipt of advance payment to clear the shipment and send it to port.
• And in case the items are not available in stock, the time taken for manufacturing depends on the size, quantity and grade.
