Hastelloy Sheet & Plate Supplier in Mumbai, India
Nicorex Alloys is an ISO 9001:2015 and ISO 14001:2015 certified importer, stockist, and supplier of Hastelloy sheets and plates in Mumbai, India. We stock grades C276, C22, B2, B3, C2000, and X in thicknesses from 0.5 mm to 150 mm, widths up to 2500 mm, and finishes including No.1, 2B, BA, No.4, and mirror.
Hastelloy is a nickel-molybdenum-chromium superalloy family made for corrosion resistance and high-temperature strength. Stocked forms include hot rolled plates, cold rolled sheets, foils, coils, and strips under ASTM B575, ASTM B333, and ASTM B435. Hastelloy is mainly found in industries such as chemical processing, petrochemical, marine, power generation, pharmaceutical, and pollution control. All shipments carry EN 10204/3.1B mill test certificates.

What are Hastelloy Sheets and Plates?
Hastelloy sheets and plates are flat-form products made from nickel-based superalloys. Sheets measure under 6 mm (0.236″) for lighter-gauge work; plates are 6 mm and above for pressure vessels. Hot rolling produces thicker plates; cold rolling gives thinner sheets with tighter tolerances. In Hastelloy, the nickel content is useful for corrosion resistance, molybdenum for reducing-acid protection, chromium for oxidising defence, and tungsten (in C-276) for chloride resistance. These alloys outperform stainless steel grades in concentrated acid service.

Available Grades of Hastelloy Sheets & Plates
Nicorex Alloys stocks Hastelloy sheets and plates in 5 grades. Each targets a specific corrosion or temperature challenge.
Hastelloy C276 Sheet & Plate
This is the most widely used Ni-Cr-Mo grade. C276 resists sulfuric, hydrochloric, and phosphoric acid across a broad temperature range, making it the default choice for mixed-acid chemical processing.
Hastelloy C22 Sheet & Plate
C22 has a higher chromium (22%), which gives it better pitting, crevice, and stress corrosion cracking resistance than C276, that too in oxidising and mixed-acid upset conditions.
Hastelloy C2000 Sheet & Plate
C2000 has copper at 1.6% that boosts sulfuric acid resistance beyond any other Ni-Cr-Mo grade. It handles both oxidising and reducing acids plus chloride-bearing environments in a single alloy.
Hastelloy X Sheet & Plate
Hastelloy X is a high-temperature alloy retaining oxidation resistance and strength up to 2200°F (1200°C). Gas turbine components, industrial furnaces, and aerospace parts are its primary applications.
Hastelloy 59 Sheet & Plate
Hastelloy C59, also known as Alloy 59, is a low-carbon nickel-chromium-molybdenum alloy that resists oxidation, corrosion, pitting, and crevice corrosion very well.
Industries and Applications of Hastelloy Sheets & Plates
- Chemical Processing: Used in reactor vessels, linings, mixing tanks, and heat exchangers.
- Petrochemical & Refinery: Flat products are found in distillation columns, condensers, and sour gas equipment.
- Marine & Offshore: Seawater systems and subsea equipment mainly use Hastelloy flat products.
- Pharmaceutical: Hastelloy sheets and plates are applied in sterile vessels, CIP systems, and high-purity piping.
- Power Generation: This industry uses hastelloy flat products in FGD scrubbers, stack liners, and superheater tubing.
- Pollution Control: Incinerators, scrubbers, and flue gas equipment use Hastelloy sheets and plates.
- Pulp & Paper: This industry uses hastelloy flat products for bleaching equipment, digesters, and recovery systems.
Frequently Asked Questions
What are the Most Common Grades of Hastelloy Sheets and Plates?
The commonly supplied grades are C276 (broadest acid range), C22 (best pitting resistance), C2000 (dual acid resistance with copper), and X (high-temperature strength up to 1200°C).
