Hastelloy C 276 Tungsten Nickel Chromium Molybdenum Alloy - China

Hastelloy C-276（UNS N10276）tungsten-ni ckel-chromium-

molybdenum alloy Features and applications overview: The alloy has

excellent corrosion to the majority of corrosive media in the oxidation

and reduction state.

It has excellent resistance to pitting corrosion,

crevice corrosion, and stress corrosion cracking.

The alloy is suitable

for containing various oxidizing and reducing media industrial chemical

processes.

High molybdenum and chromium content of the alloy can be

resistant to chloride ion erosion, and tungsten element also further

improves its corrosion resistance.

Hastelloy C-276 is one of the only

several materials resistant to the corrosion of wet chlorine gas,

hydrochloride and chlorine dioxide solution.

The alloy has significant

corrosion resistance to the high concentration of chloride salts, such

as iron chloride and copper chloride.

The metallurgical structure of Hastelloy C-276:

Hastelloy C-276 is of the face-centered cubic lattice structure.

The process performance and requirements of Hastelloy C-276:

1, The content of sulfur in fuel should be kept as low as possible.

The sulfur content of the gas should be less than 0.1%, and in heavy oil should be less than 0.5%.

2, The thermal processing temperature range of the alloy is 1200°C-950°C.

The cooling method is water-cooling or other rapid cooling.

3, All conventional welding processes is suitable to apply, such as tungsten electrode inert gas welding, plasma arc welding, handmade sub-arc welding, and metal inert gas shielded arc welding.
