Hastelloy C276 Pipe Price
Hastelloy C276 pipe prices in India typically range from ₹2,500 to ₹5,500 per kg, depending on outer diameter, wall thickness, length, quantity, and form. In the international market, prices generally range from $35 to $75 per kg on an FOB basis. Seamless pipes are generally more expensive than their welded counterparts.
The final price of C276 pipes is significantly affected by fluctuations in nickel and molybdenum prices, given the substantial presence of these metals in the alloy. Larger purchases often come with more favourable pricing. We provide C276 pipes with full material traceability and mill test certificates.
Hastelloy C276 Pipe Chemical Composition
The table below shows what Hastelloy C276 pipe is made of. Its excellent corrosion resistance mainly comes from three key elements: nickel, molybdenum, and chromium.
High molybdenum and chromium levels give Alloy C-276 its resistance to pitting, crevice corrosion, and stress corrosion cracking in chloride-bearing environments.

Hastelloy C276 Pipe Forms
Hastelloy C276 pipes come in two forms, as listed below.
- Seamless Hastelloy C276 Pipes
- Welded Hastelloy C276 Pipes
Hastelloy C276 Pipe Applications
4 key sectors use Hastelloy C276 piping where resistance to aggressive acids and chlorides is critical.
Chemical Processing
Hastelloy C276 pipes safely carry hydrochloric acid, sulphuric acid, and mixed acid flows in reactors, heat exchangers, and other demanding chemical processing equipment.
Oil and Gas
Alloy C276 pipes are specified for sour service piping per NACE MR0175 / ISO 15156, resisting sulphide stress cracking in downhole environments.
Pollution Control and Waste Treatment
FGD systems and industrial scrubbers use C276 pipes because they resist hot, acidic, and chloride-rich gases in waste treatment plants very well.
Pharmaceutical and Food Processing
Hastelloy C276 pipes serve high-purity piping systems. Cleaning with aggressive acids and sanitising agents does not degrade the pipe surface.
Hastelloy C276 Pipes vs Alternative Alloys
Hastelloy C276 outperforms SS 316 in chloride environments and resists more chemicals than Inconel 625 or Hastelloy C22 in reducing conditions.
Hastelloy C276 Pipes vs SS 316 Pipes
Hastelloy C276 pipes and Stainless Steel 316 pipes have very different amounts of nickel and molybdenum. Because of this, they offer different levels of corrosion resistance and come with different costs for industrial piping projects.
| Property | Hastelloy C276 | SS 316 |
|---|---|---|
| Ni Content | ~57% | 10–14% |
| Mo Content | 15–17% | 2–3% |
| Chloride Resistance | Excellent | Moderate |
| Acid Resistance | Wide range | Limited |
| Cost | Higher | Lower |
C276 is the correct choice when chloride or acid exposure exceeds stainless steel limits.
Hastelloy C276 Pipes vs Inconel 625 Pipes
Hastelloy C276 and Inconel 625 pipes are strong nickel alloys, but they have different chemical compositions and levels of corrosion resistance, so each is better suited to different types of chemical and industrial use.
| Property | Hastelloy C276 | Inconel 625 |
|---|---|---|
| Nickel Content | 57% min | 58% min |
| Molybdenum Content | 15–17% | 8–10% |
| Pitting Resistance | Superior (higher Mo) | Good |
| Reducing Acid Resistance | Excellent (wider range) | Good |
| Cost | Higher | Moderate to High |
Hastelloy C276 Pipes vs Hastelloy C22 Pipes
Hastelloy C276 and C22 are both nickel-molybdenum-chromium alloys, but differ in chromium and molybdenum balance, determining their suitability across oxidising and reducing chemical environments.
| Property | Hastelloy C276 | Hastelloy C22 |
|---|---|---|
| Nickel Content | 57% min | 56% min |
| Molybdenum Content | 15–17% | 12.5–14.5% |
| Reducing Acid Resistance | Superior | Good |
| Wet Chlorine Resistance | Excellent | Good |
| Formic Acid Resistance | Excellent | Moderate |
| Cost | Moderate to High | Higher |
