Alloy Scale & Oxide Conditioning
Kolene® scale conditioning processes clean heavily scaled stainless steel and superalloy products, as well as titanium and refractory metals. Kolene salt bath descaling converts refractory alloy oxides into readily soluble compounds. Conditioning in Kolene No. 1 or DGS® salt allows lower acid concentrations and temperatures and shorter dwell times in the pickling that follows.
We start with custom-engineered equipment and then add more than 85 years of chemical experience. The result is a single-source process line engineered for your product.
We build systems to fit your product, including small Unitized™ systems for precision component cleaning and 60-foot salt bath furnaces for long goods. Our descaling systems include continuous anneal and pickle lines for strip, large batch systems for wire, and long-goods units for shapes and pipe. See Metal Descaling Systems under Equipment.
Scalex® techniques are designed primarily for continuous anneal and pickle lines and may also be adapted for “coat and bake” scale conditioning of large alloy components. Contact us for current Scalex availability and application fit.
