Exceptional Resistance ASTM B564 UNS N07718 Weld Neck Flange Manufacturer in India With MTC
Buyers in South Africa, the UAE, Kenya and Canada choose this grade when a joint has to hold load under real heat turbine casings, exhaust ducting, wellhead spools and downhole tooling, where an annealed nickel alloy would simply relax. Inconel 718 holds because it's precipitation hardened, not solid-solution strengthened, giving every aged flange a 185 ksi tensile floor. Our Mumbai works forges and finishes the full range ½″ to 24″ to ASME B16.5, and 26″ to 48″ to ASME B16.47 in every class from 150 to 2500. The same material is called out as Alloy 718, UNS N07718, Werkstoff 2.4668 or Nicrofer® 5219 Nb, stocked as weld neck, slip on and blind.
Solution treatment and the double age run entirely in house get the cycle wrong and the certificate means nothing. Every flange carries heat-lot marking, PMI verification, a Brinell check and an EN 10204 3.1 mill certificate, crated for ocean transit. Send us the class, facing, bore and heat-treat condition, and our grade desk confirms the build against your isometric before any billet is cut.

These two grades often get mixed up on drawings, yet one favours strength and the other favours corrosion, so check with our grade desk.
Inconel 625 Flanges
- Strengthening: Solid solution, niobium and molybdenum in matrix
- Tensile Minimum: 827 MPa / 120 ksi annealed
- Hardness: Stays soft in the annealed condition
- Corrosion: Stronger record in seawater and acid duty
- Fabrication: Easier to weld and machine, no ageing step
Inconel 718 Flanges
- Strengthening: Precipitation hardened by niobium-rich phase
- Tensile Minimum: 1275 MPa / 185 ksi aged
- Hardness: 331 HBW minimum after the double age
- Corrosion: Good, and qualified for sour service under MR0175
- Fabrication: Weld annealed, then solution treat and age
Inconel 718 Flanges Heat Treatment & Age Hardening
Hidden strength failures in a Super Alloy 718 Slip On and Blind Flange only surface through certified inspection.
Solution Treat
Held near 954 °C to dissolve the niobium back into solution, then cooled.
First Age Step
Around 718 °C for eight hours so the strengthening phase starts to form.
Furnace Cool & Second Age
Cooled in furnace to roughly 621 °C and held, giving an 18-hour total cycle.
Prove It On Test
Brinell reading plus a tensile coupon per heat lot before the crate closes.
718 Inconel Spectacle Blind Flange Sour Service & Compliance
Buyers of wellhead and sour gas equipment in Abu Dhabi, Alberta and Secunda depend on documentation just as much as the metal itself, and our release package covers exactly that.
Nickel 718 Socket Weld Flanges Temperature Envelope
Knowing the point where this grade reaches its limit and a different alloy becomes the better option matters most.

WNR 2.4668 Threaded Flange Welding Procedure
Because its strengthening phase develops gradually, Alloy 718 resists strain age cracking better than other age hardening grades, provided the sequence is followed.
Weld In The Softer Condition
Where the design allows, join in the solution-treated state and age the assembly afterwards.
Clean Back To Bright Metal
Strip oxide, marker ink and grease well clear of the bevel on both faces.
Match The Filler
ERNiFeCr-2 wire to AWS A5.14 keeps the deposit close to parent chemistry.
Keep Heat Input Low
Stringer beads, controlled interpass temperature and minimum restraint on the joint.
Restore The Properties
Re-solution treat and re-age the weldment when full strength is required across the joint.
Inspect The Joint
Dye penetrant root and cap, then hardness check the heat-affected zone.

Inconel 718 Flanges FAQs
Clear responses to the questions buyers raise before placing an order with an Inconel 718 flanges manufacturer in India.
Which industries rely most heavily on Inconel 718 Flanges?
Aerospace turbines, rocket propulsion hardware, cryogenic vessels and sour gas wellheads, wherever strength near 700°C matters.
What drives up the cost of Alloy 718 Flanges compared to standard alloys?
High nickel with niobium and molybdenum needs double melting, solution treatment, aging and slower machining.
How does WNR 2.4851 Slip On Flange hardness compare against a 625 equivalent?
Aged 718 reaches 331 HBW minimum, harder than 625, though 625 resists general corrosion better.
Where should buyers be cautious before specifying Nickel Alloy 718 Blind Flange?
Strength drops past 650°C, machining and welding take longer, and sour service demands strict hardness limits.
What density figure applies to 718 Inconel Spectacle Blind Flange stock?
8.19 grams per cubic centimeter, slightly lighter than Inconel 600, so recheck crate weight on substitution.
Which countries receive your ASTM B637 UNS N07718 Weld Neck Flange export shipments?
Durban, Mombasa, Jebel Ali, Alberta and Ontario, each with full documents and EN 10204 3.1 certificates.
