New developments for upgrading stainless steel to improve corrosion resistance and increase equipment hygiene 127
other materials such as glass, plastic, lower alloyed stainless
steel and seals. The cleaner can be applied to complete
installations and assembled components without prior
dismantling.
Restoration. After corroded surfaces on stainless steel are
cleaned, the corrosion resistance will be restored at a higher
level. Corrosion marks remain visible, but are passivated on
their surface. Even chloride-induced pitting corrosion has
been removed and the corrosion resistance successfully
restored without prior pickling. This new technique has been
shown to have successfully repaired a considerable number
of damaged equipment and components made of stainless
steel in production plants for chemical and pharmaceutical
products, on railway coaches and handrails on seashores,
and on components for ships and offshore components.
Conclusion
To a substantial degree, the corrosion resistance of stainless
steel can be upgraded independently from alloy and structure,
as well as independently from the mechanical and other
properties of the base metal. The new methods described
here enable the selection of materials with higher strengths
and lower weights, which eventually should result in reduced
costs. The new methods also extend the lifetime of stainless
steel with upgraded corrosion resistance, maintenance and
restoration.
