Comparing Alloy 20 With 316L For A New Line?Send your acid concentration & temperature – we recommend the right grade.
Is Carpenter 20 Reducer Magnetic?
Fully Austenitic Structure
Alloy 20 is a non-magnetic, fully austenitic nickel-iron-chromium alloy in the annealed state
Slight Response After Cold Work
Heavy cold forming can introduce a mild ferromagnetic response at the surface
Restored By Annealing
A stabilising anneal at 1800-1850°F restores the fully non-magnetic condition
Alloy 20 vs 316L Stainless Steel Fittings
316L Stainless Steel
- 10-14% nominal nickel content
- No dedicated copper addition
- Attacked by mid-range sulphuric acid
- Lower material cost
Alloy 20 (UNS N08020)
- 32-38% nominal nickel content
- Copper & molybdenum dual protection
- Stable in dilute-to-boiling sulphuric acid
- Superior chloride SCC resistance

What Are The Installation and Welding Guidelines For a Nickel Alloy 20 Cross?
1. Verify Grade & Documentation
Match NPS, schedule and grade to spec; check the mill certificate.
2. Clean & Bevel The Weld End
Degrease the joint and prepare a standard 37.5° bevel.
3. Align Bore Centreline
Square the fitting to pipe and tack weld at four points.
4. Keep Interpass Below 300°F
No preheat is needed; hold interpass temperature to avoid sensitisation.
5. Fill With ERNiCrMo-3 Filler
Complete fill passes with matching or ERNiCrMo-3 filler wire.
6. Visual & Dye Penetrant Check
Inspect the bead, then hydrotest before line closure.
