Hastelloy C2000 Flanges Supplier in Mumbai, India – ASTM B564 UNS N06200
Nicorex Alloys is an ISO 9001 and ISO 14001 certified importer, stockist, trading company, and supplier of Hastelloy C2000 flanges based in Mumbai, India. We provide these Alloy C2000 flanges in compliance with the ASTM B564 / ASME SB564 standard.
The 1.3–1.9% copper sets Hastelloy C2000 flanges apart from every other Ni-Cr-Mo forged flange on the market. That deliberate copper addition gives Alloy C-2000 (UNS N06200, Werkstoff 2.4675) dual-environment capability. Molybdenum at 15–17% handles reducing acids (H₂SO₄, HCl, HF), while chromium at 22–24% resists oxidising media contaminated with ferric ions and dissolved oxygen. It has a tensile strength of 690 MPa (100 ksi) min, a yield strength of 310 MPa (45 ksi), and an elongation of 45%. Available types of Nickel alloy C2000 types are WNRF, BLRF, SORF, SWRF, threaded, lap joint, LWN, RTJ, spectacle blind, and reducing. We supply these flanges in sizes ranging from NPS 1/2”–24” (ASME B16.5); NPS 26”–60” (ASME B16.47). Available classes include 150 through 2500. These flanges are solution annealed at 1149°C (2100°F).
Hastelloy C2000 flanges are specified under NACE MR0175 / ISO 15156. This makes these flanges suitable for sour gas service. Key sectors Alloy C2000 flanges serve include sulfuric acid plants, phosphoric acid production, HF alkylation, and chemical processing. All Hastelloy C2000 flanges provided by Nicorex Alloys come with EN 10204/3.1B MTC and PMI certificates.

Chemical Composition of Hastelloy C2000 Flanges
| Element | Nickel (Ni) | Chromium (Cr) | Molybdenum (Mo) | Copper (Cu) | Iron (Fe) | Cobalt (Co) | Aluminium (Al) | Silicon (Si) | Carbon (C) | Manganese (Mn) | Phosphorus (P) | Sulfur (S) |
|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Alloy C2000 | Balance (~59) | 22.0 – 24.0 | 15.0 – 17.0 | 1.30 – 1.90 | 3.0 max | 2.0 max | 0.50 max | 0.08 max | 0.010 max | 0.50 max | 0.025 max | 0.010 max |
The 1.3–1.9% copper is the defining chemistry. No other Ni-Cr-Mo alloy includes deliberate Cu for acid resistance. Copper boosts sulfuric acid performance across all concentrations to 98%. Cr at 22–24% handles oxidising media; Mo at 15–17% covers reducing acids and pitting. The 0.010% C and 0.08% Si ceilings prevent weld HAZ precipitation, allowing as-welded service without PWHT.
Mechanical Properties of ASTM B564 Hastelloy C2000 Flanges
| Element | Nickel (Ni) | Chromium (Cr) | Molybdenum (Mo) | Copper (Cu) | Iron (Fe) | Cobalt (Co) | Aluminium (Al) | Silicon (Si) | Carbon (C) | Manganese (Mn) | Phosphorus (P) | Sulfur (S) |
|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Alloy C2000 | Balance (~59) | 22.0 – 24.0 | 15.0 – 17.0 | 1.30 – 1.90 | 3.0 max | 2.0 max | 0.50 max | 0.08 max | 0.010 max | 0.50 max | 0.025 max | 0.010 max |
Typical mill results: tensile 752 MPa (109 ksi), yield 359 MPa (52 ksi), elongation 64%. The 45% minimum elongation gives excellent forgeability for complex flange shapes. Solution annealing at 1149°C (2100°F) followed by water quench sets full corrosion performance.

Frequently Asked Questions
What is the Price of Hastelloy C2000 Flanges per Kg in India?
What Makes Hastelloy C2000 Different from C22 and C276 for Flange Applications?
Is Hastelloy C2000 Approved for Sour Gas Service per NACE MR0175?
Yes, in solution-annealed condition with hardness ≤ HRC 35.
Can Hastelloy C2000 Flanges Replace Monel 400 Flanges in HF Service?
Yes. C2000 provides comparable HF resistance to Monel 400, and oxidising media resistance that Monel 400 lacks. This makes C2000 a single-alloy solution for HF units with multiple acid exposures.
What is the ASTM Specification for Hastelloy C2000 Forged Flanges?
ASTM B564 / ASME SB564 is the standard specification for Hastelloy C2000 forged flanges.
What is the Typical Lead Time for Hastelloy C2000 Flanges?
C2000 is a speciality alloy with lower stock availability than C22 or C276. Standard sizes take 3–6 weeks. Custom sizes take 6–10 weeks.
What Welding Consumables are used for Hastelloy C2000 Flange Weld Joints?
ERNiCrMo-17 (HASTELLOY C-2000 filler metal) for matching chemistry. ERNiCrMo-3 (Inconel 625 filler) is also compatible.
