Stainless steel and seawater

Seawater rusts iron more than you might think.

This is because seawater containing chloride ions promotes the oxidation of iron.

Our factory is located near a beach, and we were told this when our previous company car broke down.

"It's not normal for a part like this to rust."

"It's rusted like a car that's been illegally dumped in the mountains."

There is no denying that it had been used harshly, but it appears to have rusted terribly.

The other company car wasn't criticized as much as that time,

"I've never seen a car this rusty," he said.

This is what happens when you just place it near seawater.

Please keep in mind that being immersed in seawater is a harsh environment for metals containing iron.
