    What is the pickling of stainless steel?

    Passivation of stainless steel can improve the corrosive resistance, manufacturing can leave behind a number of imperfections that it can’t eliminate such as heat tint or oxide scale left behind by welding
    and heat treating. The pickling of stainless steel is a chemical treatment whereby we will treat your steel with a chemical solution, usually hydrochloric or sulfuric acid and aims to eliminate impurities,
    such as stains, contaminants, and rust or scale from ferrous metals, copper, precious metals and aluminium alloys.

    Our pickling of stainless steel services includes:

    Quality control with comprehensive RAMS, COSHH reports and support documentation.
    High-quality equipment individual to each job – pumps, tanks, hoses, adaptors.
    Ferroxyl test to confirm the presence of a passive layer after the process.
    Off-site baths and immersion tanks with a clean room for drying, testing and wrapping.
    Vessel entry/confined space access.
    Optional derouging stage if required.
    Professional cleaning services if required.
    Paste passivation of small blemishes in clean rooms.
    Control of waste chemicals and disposal according to Environment Agency legislation.

    Why is the pickling of stainless steel important?

    Pickling is the process of treating stainless steel parts with an acid solution, typically hydrochloric or sulfuric acid, which can remove oxide scale and heat tint while dissolving steel flecks embedded in it, which in the long run will compromise the steel’s ability to resist corrosion. Pickling improves the material’s resistance to corrosion for long-lasting durability.
