Import Alloy Steel F22 Flanges — Buy in wholesale FOB from Supplier in India

Alloy Steel F22 Flanges from Heubach International are forged components manufactured to ASTM A182 standard, with nominal composition of 2.25% chromium and 1% molybdenum in a carbon-manganese steel matrix. These flanges are designed for high-temperature, high-pressure piping systems in oil and gas, petrochemical, and power generation applications. The F22 grade delivers enhanced creep resistance and thermal stability compared to carbon steel, with service temperatures typically up to 600 degrees Celsius depending on design stress values. Available configurations include weld neck, slip-on, blind, socket weld, threaded, lap joint, orifice, long weld neck, reducing, and ring type joint flanges to suit diverse joint designs.

The material conforms to ASME B16.5 and B16.47 dimensional standards, with pressure classes from 150# through 2500# and sizes from 1/2 inch to 48 inches. Additional standards referenced include B16.48, BS4504, BS 10, EN-1092, and DIN specifications, indicating broad international compatibility. Mechanical properties for F22 include minimum tensile strength of 415 MPa, yield strength of 205 MPa, and 20% elongation in standard test conditions. The chromium-molybdenum combination provides resistance to hydrogen attack and moderate oxidation resistance, though specific performance in sour service requires hardness verification to NACE limits. Heat treatment involves normalizing and tempering to achieve the prescribed mechanical property envelope.

Heubach International positions these flanges for critical process applications including reactor piping, heater outlets, and high-pressure steam lines where thermal cycling occurs. The Mumbai location provides access to Indian port infrastructure for export to Middle Eastern, Southeast Asian, and African project markets. Buyers should confirm with Heubach International whether the company operates as a manufacturer, stockist-distributor, or trading intermediary, as this affects lead time, inspection access, and certification chain. MOQ, exact pricing, and lead time figures are not stated in the source data and require direct inquiry. The supplier holds harbor-tier verification with no recorded response rate.

Heubach International is located at 15 Keshav Bhavan, Number 8, 1st Parsiwada Lane, Mumbai 400004, Maharashtra, India. The supplier holds harbor-tier trust status, with no response rate or average response time recorded in the available platform data. The company operates in the trading, supplying, exporting, and manufacturing of alloy steel pipe flanges, with F22 grade representing a specific product focus alongside other alloy steel grades. The Mumbai address places Heubach International in India's principal metals trading and export hub, with proximity to Jawaharlal Nehru Port for international shipment.

The supplier profile does not disclose year of establishment, factory location, production capacity, or annual revenue. It is unclear from the source whether Heubach International maintains in-house forging capabilities or sources from domestic Indian forgers. No specific quality system certifications are confirmed in the extracted data, despite references to generic standards compliance. Buyers should conduct due diligence on the supplier's actual manufacturing or trading model, request visit protocols or virtual factory access, and verify the chain of custody for material certification. The company's specialisation in alloy steel flanges suggests technical familiarity with ASTM A182 requirements, but capability depth requires direct assessment.
