Nickel Alloy / Inconel 718 (Alloy 718) Hex Bars Manufacturer in India

Inconel 718 Hex Bars Manufacturer in India

Ganpat Metal manufactures and supplies certified Nickel Alloy / Inconel 718 (Alloy 718) Hex Bars conforming to ASTM B637 / ASME SB637, AMS 5662 / 5663. Inconel 718 is a precipitation-hardenable nickel-chromium alloy combining high yield, tensile and creep-rupture strengths up to 700°C with superb post-weld cracking resistance. Widely used in gas turbines, rocket motors, and downhole oil tools.

Our Inconel 718 hexagonal bars are supplied in cold drawn, centerless turned, annealed and pickled, or precipitation hardened condition depending on standard specifications. They exhibit superior surface smoothness, precise across-flats dimensions, excellent straightness, and uniform metallurgical grain structure tailored for CNC machined components and high-tensile fastener manufacturing.

We maintain extensive inventories in sizes from 3 mm to 100 mm across flats, ready for immediate dispatch from our Mumbai central warehouse with EN 10204 Type 3.1 Mill Test Certificates and optional third-party inspection.

GM Inconel 718 Hex Bars

GM handles enquiries for Inconel 718 Hex Bars where buyers need to match hexagonal bar dimensions, across flats (AF) tolerances, and material grade to project drawings or purchase specifications. The supplied inventory covers precision cold drawn and hot rolled sizes beginning from 3 mm up to 100 mm across flats, with custom cut-to-length and surface finish options.

Grade selection should be based on the mechanical tensile properties, hardness, corrosion resistance, and chemical composition required by the project application. Buyers should also confirm the applicable standard specification (ASTM / ASME / EN), delivery condition (cold drawn, annealed, or quenched & tempered), inspection requirements, and documentation before finalizing an order.
