A Mumbai Legacy Built for Global Performance

At ViramiSteel Hub, nestled in industrial Mumbai, we understand that every bar we supply is part of a larger mission whether it’s building chemical plants, offshore platforms, or pollution-control units. That’s why our Hastelloy C276 and C22 bars aren’t just metal they’re peace of mind.

What Makes These Alloys Extraordinary?

Hastelloy C276 (UNS N10276)

A nickel-chromium-molybdenum superalloy with a touch of tungsten, built to thrive where others fail. It handles both oxidizing and reducing conditions with ease and stands firm against pitting and crevice corrosion. Its low carbon footprint maintains its corrosion resistance even after welding.

Chemical composition of Hastelloy C276
Element Content (%)
Nickel, Ni 57
Molybdenum, Mo 15-17
Chromium, Cr 14.5-16.5
Iron, Fe 4-7
Tungsten, W 3-4.50
Cobalt, Co 2.50
Manganese, Mn 1
Vanadium, V 0.35
Silicon, Si 0.080
Phosphorous, P 0.025
Carbon, C 0.010
Sulfur, S 0.010

Hastelloy C22 (UNS N06022)

The corrosion warrior of the family. With higher chromium content, it takes unyielding stands against oxidizing agents resisting chloride-induced pitting, crevice corrosion, and stress cracking with remarkable tenacity.

Chemical composition of Hastelloy C22
Element Content (%)
Chromium, Cr 20-22.5
Molybdenum, Mo 12.5-14.5
Tungsten, W 2.5-3.5
Cobalt, Co 2.5 min
Iron, Fe 2-6
Manganese, Mn 0.5 max
Vanadium, V 0.35 min
Silicon, Si 0.08 max
Phosphorus, P 0.02 max
Sulfur, S 0.02 max
Carbon, C 0.015 max
Nickel, Ni Remainder

In simple terms: C276 is robust and versatile, while C22 is elite in oxidizing corrosive environments.
