Alloy 20 Flanges
Heubach International provides Alloy 20 flanges manufactured to ASTM B462 and ASME SB462 standards, with sizes ranging from 1/2" to 48" (15 NB to 1200 NB). These flanges are available in pressure classes 150# through 2500#, as well as PN6 to PN64, and conform to ANSI/ASME B16.5, B16.47 Series A & B, B16.48, BS4504, BS10, EN-1092, and DIN standards. The material is stabilized with columbium to minimize carbide precipitation during welding, enhancing performance in high-temperature applications.
The chemical composition of Alloy 20 includes 32-38% nickel, 19-21% chromium, 2-3% molybdenum, and 3-4% copper, with a maximum carbon content of 0.07%. This composition delivers superior resistance to general corrosion, pitting, and crevice corrosion, particularly in sulfuric acid environments where conventional stainless steels such as 316 may fail. The flanges are classified under HS code 7307.19 for import and export purposes.
These flanges are widely used in chemical processing, petrochemical, pharmaceutical, and food processing industries, where resistance to chloride stress corrosion cracking and acid attack is critical. Heubach International packages the flanges in wooden crates with rust-preventive coatings to ensure safe international transit. Buyers should confirm specific sizes, pressure classes, and any additional certifications directly with the supplier.

Sourcing Alloy 20 Flanges from Heubach International - India Import Guide
Before ordering Alloy 20 flanges from Heubach International, verify the exact pressure class and dimensional standards required for your piping system. Confirm that the supplier can provide certifications for material composition, such as ASTM B462 or ASME SB462, to ensure compliance with your project specifications. Request documentation for columbium stabilization if welding is part of your assembly process.
Logistics should be discussed directly with Heubach International, as the supplier is based in Mumbai, a major hub for international trade. Clarify lead times, Incoterms such as FOB or CIF, and packaging details, as these flanges are typically shipped in wooden crates with rust-preventive coatings. Bulk orders may require additional coordination for customs clearance and handling at the destination port.
Quality checks should include verifying the chemical composition and mechanical properties of the flanges. Inspect the surface for uniformity and the absence of defects, particularly if the flanges will be used in corrosive environments. Request material test certificates and third-party inspection reports to confirm compliance with ASTM or ASME standards. Documentation such as mill test certificates and HS code 7307.19 classification should be reviewed to ensure the product meets import requirements.
