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

C276 pipes are used in chemical processing, pollution control, oil and gas sour service and pharmaceutical manufacturing.
What sizes of Hastelloy C276 pipes are available?+
Seamless pipes range from 1/8" to 6" OD. Welded pipes span 1/4" to 24" OD in schedules 5S to XXH.
What is the difference between Seamless and Welded Hastelloy C276 pipe?+
Seamless pipes (ASTM B622) have no weld seam for higher pressure integrity. Welded pipes (ASTM B619) are more economical, available up to 24" OD.
Can Hastelloy C276 pipes be welded on site?+
Yes. C276 has excellent weldability due to low carbon and silicon content, which minimises carbide precipitation during welding. GTAW, GMAW and SMAW with ERNiCrMo-4 filler metal are suitable.
What is the price of Hastelloy C276 pipe per kg?+
In India, the prices range from ₹2,500 to ₹5,500 per kg, and internationally, it costs around $35 to $75 per kg. Prices vary based on OD, wall thickness, length, quantity and form. Contact us for a current quote.
How does Hastelloy C276 pipe compare to SS 316 pipe?+
C276 pipe offers far superior corrosion resistance to SS 316 in chloride and acidic environments. SS 316 is more economical for mild conditions.
