Inconel 600 Pipe Fittings Supplier and Exporter in India
Kalpataru Piping Solution is a supplier for Inconel 600 Pipe Fittings (UNS N06600) and Inconel 601 Pipe Fittings (UNS N06601)to the industries in which the ability of a pipe system to resist oxidation and to withstand high temperatures is the key to its lifespan. Inconel 600 is a nickel-chromium-iron alloy that is easy to use in a wide range of corrosive and moderately hot environments, while Inconel 601 is used when lower alloys would be embrittled by prolonged exposure at temperatures above 600°F. We make elbows, tees, reducers, caps, crosses and stub ends in butt weld form, and socket weld/threaded forged fittings for smaller bore, high-pressure lines.
All fittings are manufactured or obtained to comply with ASTM B366, ASME B16.9, ASME B16.11 and MSS-SP-43 standards, and all are tested for chemical composition and mechanical properties, and are issued with an astm mill test certificate, complete EN 10204 3.1. We are a stockist and exporter from Mumbai with stock in all standard sizes and schedules, thus the standard requirements do not need to wait for custom production in the refinery, fabricators and EPC contractors.

What Are Inconel 600 & 601 Pipe Fittings?
Inconel 600 and Inconel 601 pipe fittings are precision-formed connectors — elbows, tees, reducers, crosses, caps and stub ends — made from nickel-chromium-iron superalloy that resists oxidation, carburisation and chloride-ion stress corrosion cracking. The high nickel content gives both grades excellent resistance to reducing environments, while the chromium content protects against oxidizing conditions. Compared with our broader inconel pipe fittings range, which also includes Inconel 625 for extreme strength applications, the 600/601 grades are the workhorse choice for furnace, heat-treatment, chemical processing and power-generation piping where dependable, cost-effective performance matters most.
