Nickel Alloy GD31Mo/SUPA75D Description

GD31MO/SUPA75D is an Super-austenitic stainless alloy well suited for work in highly corrosive wells especially where pitting, crevice corrosion and stress corrosion cracking are likely to occur. Increased levels of chromium and nickel ensure excellent general corrosion resistance whilst a higher than normal nitrogen content increases tensile and yield strength.

Nickel Alloy GD31Mo/SUPA75D Applications

Used as components in and around oil field and gas production.
