More Information About Hastelloy C-22 Pipe Spool (UNS N06022)
When you choose to buy Hastelloy C-22 Pipe Spool (UNS N06022), there have some important points we need to know before we get started.
Pitting resistance equivalency numbers (PREN) for Hastelloy C-22 Pipe Spool (UNS N06022)
Hastelloy C-22 PREN: 46
The pitting resistance equivalency number uses the alloy’s chemical makeup to guess its power against pitting corrosion. You check how much chromium, molybdenum, tungsten, and nitrogen are in the alloy. These elements help keep the steel safe. The most used formula is:
PREN = CR% + 3.3 x (MO% + 0.5 x W%) + 16 x N%Features of custom alloy C22 pipe spools
The main features include the following:
High corrosion resistance in a wide range of media.
Excellent resistance in oxidising aqueous media.
High resistance to intergranular corrosion.
Good weldability compared to other alloys in the same family.
