    Productomschrijving

    Bohler A913 (UNS S32750) is the most widely used super duplex grade on the market and is a 25%Cr ferritic-austenitic stainless steel with PREN min 41.
    The steel offers highest corrosion resistance and good strength properties and is especially suitable for use in aggressive environments containing chlorides.
    Good weldability, heat treatment after welding is not required.
    Excellent resistance to general corrosion, stress corrosion cracking, vibration cracking, pitting and crevice corrosion as well as erosion corrosion.
    Max. operating temperature for long-term use: 280°C (short-term exceeding up to 300°C permissible).
    Required surface finish: pickled or machined.
    Components exposed to seawater such as heat exchangers, feed or injection pumps, propeller shafts, highly stressed parts in chemical and waste water plants and for oil and gas production (e.g. manifolds), separators, turbine and fan blades, low-pressure compressor components.
