Superior Resistance ASTM B564 UNS N04400 Slip On Flange Manufacturer in India With Size 1/2 to 48″
Mortec Manufacturing Co is a trusted Monel 400 Flanges Manufacturer in India. We forge every B564 UNS N04400 Weld Neck Flange from certified nickel-copper billet. All work happens at our own Mumbai plant. Each blank is heat-numbered before CNC machining begins. Solution annealing happens between 1600°F and 1800°F precisely. This restores the single-phase structure and locks toughness. It performs well at cryogenic and elevated temperatures.
We also manufacture Werkstoff NR.2.4360 Puddle Flanges and Alloy 400 Reducing Flange types. Machining follows ASME B16.5, ASME B16.47 Series A/B, MSS SP-44. We offer RF, FF, RTJ facing in smooth or serrated finish. Custom bore drilling is done as per your isometric. As a direct Monel 400 Flanges Supplier in India, we hold stock. Weld Neck, Slip-On, Blind, Socket Weld and Threaded types are ex-stock. Sizes range from Class 150 through 1500. Dispatch happens within three to five days. Every order includes PMI reports and hydrostatic test records. We also provide EN 10204 3.1 or 3.2 mill test certificates.
