Inconel Supplier in India
Inconel 600, 601, 625, 718, X-750 and Incoloy 800 / 800H / 800HT in bar, sheet, plate, pipe, tube, flange, fitting and forged-ring form — ASTM B / ASME SB with EN 10204 3.1 / 3.2 MTC.
What is inconel?
Inconel is a family of nickel-chromium superalloys that keep their strength and resist oxidation, carburisation and chloride stress-corrosion cracking at temperatures from cryogenic up to about 1100 °C. The most widely used grades are Inconel 600 (UNS N06600), Inconel 601 (N06601), Inconel 625 (N06625), Inconel 718 (N07718) and Inconel X-750 (N07750).
Steelco Metal & Alloys stocks Inconel in Mumbai across round bar, sheet, plate, seamless and welded pipe, heat-exchanger tube, ASTM B564 flanges, ASME B16.9 buttweld fittings and seamless rolled rings, in both commercial and NACE MR0175 sour-service condition. Every dispatch leaves our Mumbai warehouse with an EN 10204 3.1 mill test certificate (3.2 with TUV, SGS, BV, Lloyd's or IRS witness on request), PMI verification and full heat-number traceability.

Frequently asked questions.
Answers to the questions our Mumbai desk is asked most often.
What is the difference between Inconel 625 and Inconel 718?
+
Inconel 625 is a solid-solution-strengthened Ni-Cr-Mo alloy with outstanding corrosion resistance and good weldability, used for seawater, sour gas and chemical service. Inconel 718 is age-hardenable with niobium and titanium, reaching roughly 1240 MPa tensile strength after solution treatment and ageing, and is used for high-strength rotating and bolting components up to about 700 °C.
What is UNS N06600?
+
UNS N06600 is the number for Inconel 600, a nickel-chromium-iron alloy of nominally 72% Ni, 14–17% Cr and 6–10% Fe. It resists chloride stress-corrosion cracking and oxidising atmospheres up to 1100 °C and is supplied to ASTM B166 (bar), B168 (plate, sheet, strip) and B167 (seamless pipe and tube).
Is Inconel weldable?
+
Yes. Inconel 600, 601, 625 and Incoloy 800 weld readily by GTAW, GMAW and SMAW with matching filler — ERNiCr-3 for 600, ERNiCrMo-3 for 625, and ENiCrFe-3 electrodes. Inconel 718 requires solution treatment and ageing after welding to restore full properties.
What is the price of Inconel per kg in India?
+
Inconel pricing depends on the grade, the form and the current LME nickel and moly surcharge — 625 and 718 carry a significant premium over 600. Send your grade, size, form and tonnage and we quote the same working day with the live stock position from our Mumbai warehouse.
