Care of Stainless Steel
Stainless Steel Corrosion
Corrosion resistance is greatest when a layer of oxide film is formed on the surface of stainless steel. If film is disturbed or
destroyed, stainless steel becomes much less resistant to corrosion and may rust, pit or crack.
Corrosion pitting, rusting and stress cracks may occur due to chemical attack. Use only cleaning chemicals specified by a
reputable chemical manufacturer for use with 300 series stainless steel. Do not use excessive concentrations, temperatures
or exposure times. Avoid contact with highly corrosive acids such as hydrofluoric, hydrochloric or sulfuric. Also avoid
prolonged contact with chloride-containing chemicals, especially in presence of acid. If chlorine-based sanitizers are used,
such as sodium hypochlorite (bleach), do not exceed concentrations of 150 ppm available chlorine, do not exceed contact
time of 20 minutes, and do not exceed temperatures of 104°F (40°C).
Corrosion discoloration, deposits or pitting may occur under product deposits or under gaskets. Keep surfaces clean,
including those under gaskets or in grooves or tight corners. Clean immediately after use. Do not allow equipment to set
idle, exposed to air with accumulated foreign material on the surface.
Corrosion pitting may occur when stray electrical currents come in contact with moist stainless steel. Ensure all electrical
devices connected to the equipment are correctly grounded.
Elastomer Seal Replacement Following Passivation
Passivation chemicals can damage product contact areas of WCB equipment. Elastomers (rubber components) are most
likely to be affected. Always inspect all elastomer seals after passivation is completed. Replace any seals showing signs of
chemical attack. Indications may include swelling, cracks, loss of elasticity or any other noticeable changes when
compared with new components.
