More Information About Hastelloy C-22 Flange (UNS N06022)
When you choose to buy Hastelloy C-22 Flange (UNS N06022), there have some important points we need to know before we get started.
Pitting resistance equivalency numbers (PREN) for Hastelloy C-22 Flange (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%How to Purchase Hastelloy C-22 Flange (UNS N06022)
