LONG-LASTING APPEARANCE WITH THE RIGHT TYPE OF STAINLESS STEEL
A 304 STAINLESS STEEL DOOR HANDLE WHERE ACID-RESISTANT STAINLESS STEEL 316 WAS RECOMMENDED
We recommended an acid-resistant stainless steel 316 handle for installation on the front door in the coastal zone, but the customer opted for a standard one 304 anyway.
The handle was installed on a front door in a coastal area for about three months before it started to corrode. Due to the effects of the sea, the corrosion started to spread.
Both types of stainless steel are resistant to corrosion, but 304 to a lesser extent. This does not mean that every 304 stainless steel handle will corrode in a harsh environment, but it is more likely.
