Passivation of stainless steel systems must follow recognized industry standards to ensure consistent results and proper corrosion resistance.
Two commonly referenced standards for stainless steel passivation are ASTM A967 and ASTM A380.
Facilities searching for passivation services in Canada often encounter these standards when evaluating service providers.
ASTM A967 defines chemical passivation treatments used to remove iron contamination from stainless steel surfaces.
The standard describes acceptable chemical solutions and testing methods used to verify successful passivation.
Key elements include:
ASTM A380 provides guidelines for cleaning, descaling, and passivating stainless steel equipment.
The standard covers a broader range of surface treatment processes used during fabrication and maintenance.
These processes include:
Following recognized standards ensures stainless steel systems maintain corrosion resistance and meet regulatory expectations.
Facilities working with experienced providers offering passivation services in Canada often prioritize companies that follow ASTM and ASME standards.
If you are also deciding between treatment types, our guide on passivation vs pickling for stainless steel systems explains when each process may be used.
Understanding standards is important, but so is knowing when to apply them. This related article on when stainless steel piping should be passivated explains common scenarios where passivation is required after fabrication, commissioning, maintenance, or repairs.
