14 · Comparison

Difference Between Hastelloy C22 And C276 Flanges

Both are Ni-Cr-Mo-W alloys - the Cr and Mo split decides where each fits. Mill-direct from a Hastelloy C22 flange manufacturer in India.

Hastelloy C276 (N10276)

  • Chromium: 14.5–16.5%
  • Molybdenum: 15.0–17.0%
  • Yield Strength: 41 ksi / 283 MPa min
  • Best For: Reducing acids, HCl service
  • Weld HAZ: More sensitive to precipitation

Hastelloy C22 (N06022)

  • Chromium: 20.0–22.5%
  • Molybdenum: 12.5–14.5%
  • Yield Strength: 45 ksi / 310 MPa min
  • Best For: Oxidizing + reducing, wet chlorine, FGD
  • Weld HAZ: Better as-welded stability

How To Weld Hastelloy C22 Flanges

Follow these four steps to avoid cracking and preserve corrosion resistance at the joint.

1

Joint & Cleaning

Grind bevel bright metal; degrease – no carbon contamination.

2

Filler Selection

ERNiCrMo-10 (GTAW/GMAW) or ENiCrMo-10 (SMAW) filler wire.

3

Low Heat Input

Stringer beads, interpass temp under 150°C to avoid cracking.

4

Purge & Inspect

Back-purge with argon; follow with dye-penetrant/RT check.

WNR 2.4602 Weld Neck Flange Manufacturing Process

Four stages take every flange from raw billet to a heat-stamped finished piece. As an ISO-certified Hastelloy C22 flange manufacturer in India, quality drives every step.

1

Forging

Billet upset-forged to flange blank under controlled temperature.

2

Heat Treatment

Solution-annealed to dissolve carbides and set final grain size.

3

CNC Machining

Bore, face, bolt-holes cut to ASME B16.5/B16.47 tolerances.

4

Test & Mark

Mechanical, PMI and NDT testing before heat-number stamping.
