Hastelloy Supplier in Visakhapatnam

Hastelloy Supplier in Visakhapatnam: C276, C22, C-4 and B3 for Parawada API Reactors and Refinery Acid Duty

Bulk-drug and API plants around Parawada work with chlorinating agents, mixed acids and solvents in the same reactor, often batch after batch. Ganesh Metals supplies Hastelloy C276, C22, C-4, B2 and B3 for that kind of duty, to the plants themselves, to the equipment builders that supply them, and to refinery and Atchutapuram SEZ process units. We supply plate, sheet, strip, circles, round bar and pipe as a high-nickel alloy stockist, supplier and processor in Mumbai since 1992, with the mill's EN 10204 3.1 certificate on every lot.

We provide direct door delivery to your company in Visakhapatnam. Hastelloy is cut and packed at our Mumbai shop and sent to Jawaharlal Nehru Pharma City at Parawada, the Atchutapuram SEZ, the Malkapuram refinery area or Autonagar after we agree the dispatch plan. Share your reaction chemistry, chloride level and peak temperature, and we will help you decide between C276, C22, C-4 and B3.

Hastelloy grades and specifications

Hastelloy C276 (UNS N10276, W.Nr 2.4819): plate, sheet and strip ASTM B575 / ASME SB575, bar ASTM B574, seamless pipe ASTM B622, welded pipe B619, welded tube B626.

Hastelloy C22 (UNS N06022, W.Nr 2.4602): same product specs as C276 (B575, B574, B622, B619, B626), with fittings to ASTM B366 (WPHC22).

Hastelloy C-4 (UNS N06455, W.Nr 2.4610): plate and sheet ASTM B575, bar ASTM B574, pipe ASTM B622 / B619. Mill origin and availability are confirmed for each enquiry.

Hastelloy B2 / B3 (UNS N10665 / N10675): plate and sheet ASTM B333, bar ASTM B335, seamless pipe ASTM B622, welded pipe B619. B3 now usually replaces B2.

Forgings and flanges: ASTM B564 / ASME SB564. Fittings: ASTM B366 (WPHC276, WPHC22, WPHB-3).

Typical chemistry: C276 Mo 15.0–17.0%, Cr 14.5–16.5%, W 3.0–4.5%, Fe 4–7%. C22 Cr 20.0–22.5%, Mo 12.5–14.5%. C-4 Cr 14–18%, Mo 14–17%, Ti 0.7% max, with very low iron. B3 Mo 27–32%.

Fabrication notes: C276 and C22 can be welded without post-weld heat treatment in most process duties because carbon and silicon are kept low. C-4 holds its corrosion resistance after long exposure in the 650–1040 °C range, which helps where parts are re-heated during fabrication or repair.

Hastelloy forms we supply

API reactor builders mostly ask for C276 and C22 plate cut to shell, dish and nozzle sizes, circles for blanks and agitator blades, and round bar for shafts, thermowells and baffles. Refinery jobs need sheet for liners and pipe cut to spool length. We also supply strip, seamless and welded tube, flanges and fittings. The heat number stays on each piece so your validation file can trace it back to the MTC. Sizes are on request. Estimate weight with the metal weight calculator.

FAQs — Visakhapatnam

Do you supply Hastelloy to Visakhapatnam?

Yes. We send C276, C22, C-4 and B2/B3 plate, sheet, bar and pipe to Parawada, Atchutapuram, Autonagar and the rest of Visakhapatnam from our Mumbai stock. We provide direct door delivery to your company in Visakhapatnam.

How long does delivery to Visakhapatnam take?

That depends on the transporter and route. We confirm the dispatch plan with you when the order is placed.

C276 or C22 for an API reactor that runs both oxidising and reducing steps?

C22 has more chromium, so it copes better with oxidising steps and ferric or cupric ions. C276 has more molybdenum and tungsten, so it holds up better in reducing acids. For a multi-purpose reactor, C22 is often chosen, but the batch chemistry decides. Send your process steps and we will help you compare.

Where is Hastelloy C-4 used instead of C276?

C-4 is chosen where parts will be heated for long periods during fabrication or service, because it resists the grain-boundary attack that can follow such heating. In most other acid duties, C276 or C22 is the usual pick.

Will the material come with a 3.1 certificate for inspection?

Yes. Every supply comes with the mill's original EN 10204 3.1 test certificate, and heat numbers are marked on each piece. Call or WhatsApp +91 99872 73700 to discuss your use.
