Chromium-molybdenum alloy steel (or chrome moly), is an alloy used for high pressure and temperature use. It is used in oil and gas, energy, construction and the automotive industries because of its corrosion resistance and high-temperature and tensile strength. The added reliability provided by chrome moly means that it is the material of ...
routinely in the manufacturing steel mill before the steel is delivered. Mill descaling is usually a two-stage process, one to mechanically loosen the 'mill-scale', the second to lift the loosened scale clear from the metal surface. The exposed metal surface is then usually pickled to remove the metal layer that was immediately beneath the ...
