Alloy 20 Supplier in Vadodara: Plate, Pipe and Bar for Sulphuric Acid Duty in Nandesari, Padra and Makarpura

Alloy 20 Supplier in Vadodara: Plate, Pipe and Bar for Sulphuric Acid Duty in Nandesari, Padra and Makarpura

Sulphuric acid is one of the most common process chemicals in the chemical estates around Vadodara, from dye intermediates in Nandesari to pharma and specialty chemicals in Padra and Por. Alloy 20 was developed for exactly that duty. Its nickel, copper and molybdenum resist hot sulphuric acid, and niobium keeps welds sound. Ganesh Metals supplies Alloy 20 as plate, sheet, strip, circles, round bar and pipe to plants and to the pump, valve and vessel builders that serve them. We have been a high-nickel alloy stockist, supplier and processor in Mumbai since 1992.

We provide direct door delivery to your company in Vadodara. Alloy 20 is cut and packed at our Mumbai shop and sent to Nandesari, Padra, Por, Ranoli, Makarpura, Savli, Manjusar or Waghodia after we agree the dispatch plan. Tell us the acid concentration, temperature and any chlorides, and we will check whether Alloy 20 is right or whether a higher grade is safer.

Alloy 20 grade and specifications

Alloy 20 (UNS N08020, W.Nr 2.4660): plate, sheet and strip ASTM B463 / ASME SB463, bar ASTM B473, seamless pipe ASTM B729, welded pipe ASTM B464, welded tube ASTM B468.

Alloy 20 fittings: ASTM B366 (WP20CB). Forgings and flanges: ASTM B462 / ASME SB462. Pump and valve shops also buy B473 bar for shafts, stems and trim.

Equivalents: UNS N08020 · W.Nr 2.4660 · often known as Carpenter 20Cb-3 or 20Cb3. The cast version used for pump casings and valve bodies is CN7M.

Typical chemistry (ASTM B463): Ni 32.0–38.0%, Cr 19.0–21.0%, Cu 3.0–4.0%, Mo 2.0–3.0%, Nb 8×C to 1.00%, C 0.07% max, iron balance. Density about 8.08 g/cm³.

Annealed minimums (ASTM B463): tensile 551 MPa, yield 241 MPa, elongation 30%.

Welding: the niobium in Alloy 20 limits carbide precipitation next to the weld, so fabricated parts are normally used as welded in acid service. Use a matching filler and tell us if your procedure calls for a specific one.

When to step up: for hot hydrochloric acid, high chlorides or mixed acids with oxidising salts, Incoloy 825 or Hastelloy C276 may be needed. We help you compare before you order.
