Consisting of two-thirds nickel and one-third copper, Monel 400 Flanges are superior to 316 Stainless Steel Flanges in deaerated hydrofluoric acid, high velocity brine and seawater. These flanges due to their nickel copper alloy have a better resistance against aggressive process environment than chromium based alloys and therefore are indispensable in offshore risers, seawater desalination units, sour gas wellheads and propeller shafting systems. Ganpat Industrial Corporation – being an Indian manufacturer and exporter of flanges and fittings made of Nickel Alloys for more than 25 years – makes each flange using certified ASTM B564 billet.

Frequently Asked Questions
Is a Monel 400 Flange magnetic?
It is slightly magnetic at room temperature, unlike austenitic stainless steel flanges.
Can Monel 400 Flanges handle hydrofluoric acid?
Yes. Monel 400 is one of the few alloys resistant to de-aerated hydrofluoric and hydrochloric acid.
What is the difference between Monel 400 and Monel K500 flanges?
Monel K500 is age-hardened for roughly double the tensile and triple the yield strength of Monel 400.
Does Monel 400 Flange need post-weld heat treatment?
Generally post-weld heat treatment not required in Monel 400 Flange.
What is the minimum order quantity?
Ganpat Industrial supplies from small trial lots to full container loads, share size and quantity for a factory price.
