Import Alloy Steel F5 Flanges — Buy in wholesale FOB from Supplier in India

Heubach International supplies Alloy Steel F5 Flanges manufactured from chromium-molybdenum alloy steel conforming to ASTM A182 Grade F5, with a nominal composition of 1Cr-1/2Mo featuring 4-6% chromium and 0.45-0.65% molybdenum. These flanges are engineered for sustained high-temperature service, maintaining mechanical integrity at operating temperatures up to approximately 600 degrees Celsius. The product range covers pressure classes from 150 through 2500 lbs, with nominal sizes from 1/2 inch (15 NB) to 24 inches, though the full source extends to 48 inches (1200 NB). Available configurations include weld neck, slip-on, blind, and raised face designs, with additional variants such as orifice, socket weld, threaded, long weld neck, ring type joint, and reducing flanges available on specification.

The F5 grade derives its elevated-temperature performance from the combined effect of chromium, which enhances oxidation resistance and high-temperature strength, and molybdenum, which improves creep resistance and prevents softening at sustained heat. Carbon content is held to 0.15% maximum to minimise susceptibility to carbide precipitation during welding and thermal cycling, a critical factor for welded piping systems in cyclic service. Mechanical properties per the supplied data include minimum tensile strength of 485 MPa, minimum yield strength of 275 MPa, and 20% minimum elongation, though buyers should request certified mill test reports to verify actual values for their specific heat. The low carbon content relative to higher-carbon creep-resistant steels renders F5 suitable for applications where post-weld heat treatment may be impractical.

These flanges serve oil and gas pipeline construction, petrochemical processing units, refinery heat exchangers, and power generation boiler piping systems where ASME pressure piping codes govern component selection. Buyers typically procure F5 flanges for projects specifying ASTM A182/ASME SA182 material standards, with dimensional conformance to ANSI/ASME B16.5 or B16.47 Series A and B. Trade terms cited include CFR and CIF for international shipments, with export-ready packaging and mill test certificates standard. Importers should confirm Incoterms, inspection protocols, and certificate requirements directly with Heubach International before placing orders, as response rate data is not available from the listing.

Heubach International operates from 15 Keshav Bhavan, No.8, 1st Parsiwada Lane, Mumbai 400004, Maharashtra, India. The company functions as a manufacturing, supplying, trading, and exporting unit of alloy steel pipe flanges and related piping components. Its trust tier is classified as harbor, with a response rate of 0.00% and average response hours recorded at zero, indicating no response data is currently captured or reported for this profile. Buyers should note this absence of response metrics when evaluating communication reliability.

The listing presents Heubach International as a known entity in the alloy steel flange trade, with product coverage spanning multiple ASTM grades including F5 and F9 variants. The supplier emphasises export readiness, mill test certification, and standard international trade terms. No verified production capacity, workforce size, revenue figures, or named client references appear in the source data. The company's Mumbai location places it within India's established metals trading and manufacturing corridor, though buyers should conduct independent due diligence on manufacturing credentials and quality system certifications prior to commitment.
