    Characteristics and field of use
    UTP 6635 is a basic-coated stick electrode for joinings and surfacings0n corrosion resistant
    martensitic CrNi-steels and corresponding cast steels. The application field is in the
    armatures- and power station construction. The weld deposit has an increased resistance to
    cavitaion and erosion also at working temperatures up to 350 °C.
    UTP 6635 is weldable in all positions, except vertical-down. Easy slag removal, smooth and
    notch-free welding surface. Recovery: 130 %.
