Precision Machined ASTM B564 UNS N06600 Slip On Flange Manufacturer in India At Zero-Brokerage Factory Rates

South Africa, the UAE, Kenya and Canada are where most of our nickel chromium orders come from these days mainly because furnace lines, caustic circuits and chloride heavy headers need a flange that opens clean at the next turnaround and not one that seizes up. We forge and finish Inconel 600 flanges at our Mumbai works from half inch right through to 24 inch and Class 150 up to 2500, with larger diameters machined to order, so either way your shutdown list is not stuck waiting on an import shipment. Buyers also know this material as Alloy 600 flanges, Nickel Alloy 600 flanges and UNS N06600 flanges and we supply it as weld neck, slip on and blind types.

Each flange goes out with heat lot marking, PMI verification and an EN 10204 Type 3.1 mill test certificate crated to handle a long ocean leg without issue. Forging, annealing and CNC facing all happen in house so there is no trader sitting between the billet and your PO adding margin. Tell us the class, facing and bore and our grade desk checks the build with you before anything moves so what lands at site is exactly what the isometric called for.

Inconel 600 Flanges Vs Stainless Steel 316 Flanges

Buyers stepping up from 316 typically want clarity on what the added investment delivers, so speak with our grade desk before finalising the switch.

Stainless Steel 316 Flanges

  • Base Metal: Iron-based, roughly 10–14% nickel
  • Chloride SCC: Vulnerable at raised temperature
  • High-Heat Duty: Scaling limits long furnace exposure
  • Caustic Service: Attacked by strong hot caustic
  • Relative Cost: Lowest of the two

Inconel 600 Flanges

  • Base Metal: Nickel-based, 72% minimum nickel
  • Chloride SCC: Highly resistant thanks to nickel content
  • High-Heat Duty: Chromium film resists scaling in furnace air
  • Caustic Service: A standard choice for caustic circuits
  • Relative Cost: Higher, repaid in avoided shutdowns

11 · Installation

Werkstoff NR. 2.4816 Threaded Flange Welding Procedure

Nickel alloy weld puddles behave more sluggishly than steel, so a clean bevel, correct filler and controlled heat are what keep an N06600 joint sound.

1

Clean Back To Bright Metal

Remove oxide, marker ink and grease well clear of the bevel on both sides.

2

Match The Filler

ERNiCr-3 wire to AWS A5.14, or ENiCrFe-3 electrode to AWS A5.11.

3

Keep Heat Input Low

Stringer beads and a controlled interpass temperature, no weaving.

4

Inspect The Joint

Dye penetrant the root and cap; post-weld heat treatment is not normally required.

12 · Fabrication

Nickel 600 Socket Weld Flanges Bolting & Assembly Guidance

Correct metallurgy, a suitable gasket and a careful tightening pattern keep an N06600 joint sealed without galvanic complications.

Matching BoltingAlloy 600 stud bolts and heavy hex nuts machined from B166 bar keep the joint one metallurgy.
Gasket ChoiceSpiral wound with an Alloy 600 winding strip and graphite filler suits most hot service.
Tightening SequenceCross-pattern in four rising passes, then a final pass round the clock.
Galvanic CareAvoid pairing with plain carbon steel bolting in wet chloride or seawater duty.
Ask For The Weld NoteSend your wall thickness and process – we return a filler and bevel note with the flange.

ASTM B564 UNS N06600 Weld Neck Flange Price Factors

Pricing rests on four variables, share your requirement and rely on us as your trusted Inconel 600 flanges supplier in India

Nickel Market RateAt 72% minimum nickel, the billet cost follows the nickel exchange, not the steel index.
Size And Pressure ClassA Class 1500 hub carries far more forged weight than the same bore in Class 150.
Type And FacingOrifice, long weld neck and RTJ work take more machine hours than a plain slip-on.
Inspection LevelWitnessed hydrostatic, ultrasonic or a full TPI release adds cost and calendar days.
14 · How It’s Made

Nickel Alloy 600 Blind and Weld Neck Flange Manufacturing Process

Forged, annealed and finished entirely on site so every production stage remains under a single quality plan.

1

Billet & Upset

N06600 billet cut to weight and upset to the flange blank profile.

2

Closed-Die Forging

Hub and disc formed in die, giving grain flow around the neck.

3

Anneal & Quench

Annealed and cooled to restore a uniform solid-solution structure.

4

CNC Face, Drill & Mark

Facing, bore, bolt holes, then PMI and heat-lot stamping.

17 · FAQs

Inconel 600 Flanges FAQs

Straight answers to what buyers ask before releasing an order, we're an Inconel 600 flanges manufacturer in India.

What is Inconel 600 Flanges used for?

A nickel-chromium alloy for high heat and corrosive service – furnaces, heat treatment, caustic lines, nuclear parts, and food processing equipment.

Is a Class 600 flange the same as a WNR 2.4816 Slip On Flange?

No. Class 600 is a pressure rating; WNR 2.4816 Slip On Flange is the material grade (UNS N06600). Always specify both.

Are Alloy 600 Flanges and Inconel 600 Flanges the same material?

Yes. Same material, different names – Inconel® 600, Alloy 600, UNS N06600, Werkstoff 2.4816, Nickelvac® 600, and Sanicro® 70 all refer to the same grade, suppliable under ASTM B564.

What is the density of ASTM B564 UNS N06600 Weld Neck Flange material?

8.47 g/cm³ (0.306 lb/in³) – close to stainless steel, so your existing lifting and support calculations should still work.

Why are Alloy 600 Orifice Flanges more expensive than stainless steel flanges?

It's mostly nickel (72% min) and chromium, so material cost follows the nickel market, not cheaper steel. It's also harder to forge and machine, which adds to the price.

Do you export Nickel Alloy 600 Blind Flange to South Africa, Kenya, the UAE and Canada?

Yes – we export to Durban, Johannesburg, Mombasa, Nairobi, Jebel Ali, Abu Dhabi, and Canada, with full documentation and mill test certificates included.
