Hastelloy C22 Chemical Composition – Key Differences from C276

Element	Hastelloy C22 (%)	Hastelloy C276 (%)
Nickel (Ni)	Balance (56% approx)	Balance (57% approx)
Chromium (Cr)	20.0 – 22.5% (HIGHER)	14.5 – 16.5%
Molybdenum (Mo)	12.5 – 14.5%	15 – 17%
Tungsten (W)	2.5 – 3.5%	3 – 4.5%
Iron (Fe)	2.0 – 6.0%	4 – 7%
Cobalt (Co)	≤ 2.5%	≤ 2.5%

Mechanical Properties – Hastelloy C22 Round Bar

Tensile Strength	690 MPa (min)
Yield Strength (0.2% offset)	310 MPa (min) – slightly higher than C276
Elongation	45% (min) – better ductility than C276
Hardness	HRC ≤ 32 / HB ≤ 215

Key Insight: Higher chromium in C22 provides superior resistance to oxidizing chemicals like nitric acid, whereas C276's higher molybdenum gives it an edge in reducing environments. Choose C22 for mixed acid applications.

FAQ – Hastelloy C22 Round Bar in Mumbai, Maharashtra

Hastelloy C22 vs C276 – which is better for my application?

If your environment contains oxidizing chemicals (nitric acid, ferric ions, wet chlorine) – choose C22. If it's strong reducing acids (pure HCl, H2SO4) – C276 may be better. Our team can help you choose the right grade for your specific conditions.

Is Hastelloy C22 more expensive than C276?

Often C22 is comparable or slightly lower in price because it has lower molybdenum content. But prices fluctuate based on raw material costs. Call us for current pricing for Hastelloy C22 Round Bar in Mumbai.

Does Hastelloy C22 require post-weld heat treatment?

No! One of C22's key advantages is that it maintains corrosion resistance in the as-welded condition. No PWHT needed, saving time and cost on fabrication.

What is the delivery time for C22 round bar in Maharashtra?

2-4 days for Mumbai, Pune, Thane, Nashik, Nagpur. 5-7 days for other Maharashtra cities. Custom sizes may take 10-14 days.
