Hastelloy C22 Pipe Applications
C22 earns its cost where lower alloys pit, crack or need frequent replacement.
How to Identify Genuine Hastelloy C22 Pipe
Four quick checks when C22 pipe reaches your site.
Check 1
Read the Marking
Spec, UNS N06022, size and heat no. on each length.
Check 2
Match the MTC
Heat no. on pipe must match the 3.1 certificate.
Check 3
Run PMI
Cr 20–22.5% with W present rules out C276 and 625.
Check 4
Magnet Test
Annealed C22 is non-magnetic. A pull means wrong alloy.
