Pitting resistance equivalent number

The pitting resistance equivalent number is like a superhero trade mark that helps you know how well a metal superhero can resist getting tiny holes poked into them by villains.

The number is calculated by looking at the different elements that make up the metal and how they work together to fight against pitting.

Each element has a certain level of strength against pitting, and the pitting resistance equivalent number adds up all those strengths to give the metal an overall score.

The higher the number, the tougher the metal is against pitting. Just like how a superhero with a higher power level can take on more villains.

So, if you want to know which metal is the best at fighting against pitting, you can check out their pitting resistance equivalent numbers and choose the one with the highest score – just like how you would pick the strongest superhero to fight the bad guys!
