SSs susceptible to crevice corrosion and stress corrosion cracking in chloride-containing environments shall be coated unless otherwise specified by the facility owners.
Coatings for SSs or high nickel-chromium alloys shall not contain more than 200 mg/kg leachable chloride in accordance with ASTM C 871.16 In general, epoxy resin itself does not contain more than 10 mg/kg leachable chloride. Such coating formulations shall not contain metallic zinc, because of the possibility of inducing liquid metal cracking. |
