Hastelloy C2000 Sheets & Plates Supplier in Mumbai – ASTM B575 N06200
Nicorex Alloys is an ISO-certified supplier and stockist of Hastelloy C2000 sheet and plate based in Mumbai, India. We supply these flat products manufactured to ASTM B575 / ASME SB-575.
Alloy C2000 (UNS N06200, Werkstoff Nr. 2.4675), also known as Hastelloy Alloy C-2000, is a nickel-chromium-molybdenum-copper material with a nominal balance of Ni 59%, Cr 23%, Mo 16%, and Cu 1.6%. The deliberate copper addition sets Nickel Alloy C-2000 apart from every other Ni-Cr-Mo sheet product on the market. Sheet thickness ranges from 0.5 to 6.0 mm; plate thickness from 6.0 to 50 mm. Widths span 1000 to 2500 mm, lengths from 2000 to 6000 mm. Available forms include hot-rolled plate, cold-rolled sheet, strip, coil, and foil. Surface finishes cover 2B, 2D, BA, No.1, No.4, and mirror. Solution annealing at 1149°C (2100°F) with rapid quench restores full corrosion performance after fabrication. The melting range falls between 1328-1358°C (2422-2476°F). Minimum tensile strength is 690 MPa (100 ksi), and elongation reaches 45%, giving cold-rolled sheets strong formability for vessel linings and pressed components.
Copper at 1.6% gives Hastelloy C2000 sheet a dual advantage: Mo handles reducing acids (H₂SO₄, HCl, HF), while high Cr (23%) resists oxidising media contaminated with ferric ions and dissolved oxygen. That dual resistance makes the Alloy C2000 plate the single most versatile Ni-Cr-Mo flat product for mixed-acid chemical processing environments. Target industries include oil and gas, chemical and petrochemical, marine, power generation, and pharmaceutical. Every shipment carries EN 10204/3.1B mill test certificates, PMI reports, and full traceability documentation.

Chemical Composition of Hastelloy C2000 Sheets & Plates
| Element | Nickel (Ni) | Chromium (Cr) | Molybdenum (Mo) | Copper (Cu) | Iron (Fe) | Cobalt (Co) | Manganese (Mn) | Aluminium (Al) | Silicon (Si) | Carbon (C) |
|---|---|---|---|---|---|---|---|---|---|---|
| Composition (%) | Balance (~59) | 22.0–24.0 | 15.0–17.0 | 1.3–1.9 | 3.0 max | 2.0 max | 0.50 max | 0.50 max | 0.08 max | 0.015 max |
Copper at 1.3-1.9% boosts sulfuric acid resistance beyond what any other Ni-Cr-Mo sheet offers. Cr at 23% protects flat products used as vessel linings and cladding in oxidising process streams. The 0.015% C ceiling keeps the weld HAZ free of carbide precipitation, so sheets and plates retain full corrosion resistance as-welded.

Corrosion Performance of Hastelloy C2000 in Sheet & Plate Applications
Hastelloy C2000 corrosion resistance covers both oxidising and reducing acids in a single flat-product grade. Sheets used as reactor linings and plates used for tank cladding resist sulfuric acid up to 80% concentration at elevated temperatures, a range where C-276 and C-22 fall short. In hydrochloric acid up to 10%, Alloy C2000 sheet holds corrosion rates below 0.28 mm/yr at 52°C.
The critical pitting temperature in acidified 6% FeCl₃ (ASTM G48) reaches 145°C, and the critical crevice temperature hits 80°C. In seawater crevice tests (U.S. Navy, LaQue Labs), C2000 showed zero attack in both still and flowing conditions after 180 days. These results drive purchasing decisions where plate cladding and structural panels face chloride-rich, mixed-acid service.
