ASTM B473 Alloy 20 Bars Supplier, Exporter, Manufacturer

Bar Forms and Finishes We Supply


Round bars run 6mm to 250mm diameter in black, peeled, or bright polished finish. Rectangle and hex sections cut to length on request. Forged bar covers diameters above 250mm for large valve bodies and pump shafts. Square and flat bars complete the range for fabricators building acid-handling equipment.


Leoscor Alloys manufactures and supplies ASTM B473 Alloy 20 Bars from our Mumbai facility to buyers across India and overseas. As an established Alloy 20 round bar supplier, we stock this columbium-stabilized nickel-iron-chromium material in round, rectangle, hex, square, and flat sections. Also known as WNR 2.4660, UNS N08020, Carpenter 20, and 20Cb-3, every Alloy 20 bar we ship carries mill test certificates and third-party inspection reports.

The alloy combines 32 to 38% nickel with 19 to 21% chromium and 3 to 4% copper. That copper addition stabilizes the passive oxide layer in both oxidizing and reducing acid mixtures. A 25mm Alloy 20 round bar machined into a valve stem for a phosphoric acid line will outlast an equivalent 316 stainless part by years, not months, because standard austenitic grades lose their passive layer under the same conditions.

Frequently Asked Questions

Pump shafts, valve stems, and fasteners in sulfuric acid, phosphoric acid, and pharmaceutical reactor equipment rely on Alloy 20 round bar for its resistance to hot acid attack.

Copper in the alloy stabilizes the passive oxide layer, so the bar resists pitting and stress corrosion cracking where 316 stainless fails within months of service.

Round bar stock runs 6mm to 250mm diameter, with forged bar covering larger sizes for pump shafts and valve bodies.

Check for mill test certificates, third-party inspection reports, and batch traceability. Leoscor Alloys issues both with every shipment.

Petrochemical, fertilizer, pharmaceutical, and chemical processing plants specify it for equipment exposed to sulfuric and phosphoric acid.
