Effect of Crevice Former on the Crevice Corrosion of 316L Stainless Steel in Synthetic Tap Water

To restrain the failure of plate heat exchanger in customer boiler working fluid, the effect of crevice former type on the corrosion behavior of Type 316L (UNS S31603) stainless steel plate was investigated using electrochemical methods and surface analysis in chloride-containing synthetic tap water.

To restrain the failure of plate heat exchanger (PHE) in customer boiler working fluid the effect of crevice former type on the corrosion behavior of 316L Stainless steel was investigated using electrochemical methods and surface analysis in chloride-containing synthetic tap water. Although the localized corrosion under metal-metal crevice condition was easily initiated than that under metal-gasket crevice specimen the anodic current under metal-metal crevice condition was less than that under metal-gasket crevice condition in high anodic potential. Narrow crevice gap which was formed under gasket concentrated the anodic dissolution at the mouth of crevice and then caused the perforation of PHE in the field condition. Moreover the anodic dissolution depth of metal-gasket crevice specimen was deeper than those of metal-metal crevice specimen. Therefore the metal-gasket crevice leadingly affects to PHE failure.

Key words: weld, steel, corrosion, stress corrosion cracking, polarization
