Crack resistant weld metal conditioned by the high-basicity slag in combination with very low hydrogen content. Well suited for the economic joining of high strength steels and cryogenic fine grain structural steels with Rp0,2 > 890 MPa (129 ksi). To reach the optimal mechanical properties, the energy absorbed per unit length of weld 15 kJ/cm should not be exceeded. The working temperature should be between 100°C (212 °F) and 150°C (302 °F) . As welding flux FL 155 should be used because of its high basicity and low hydrogen content.
TM-pipe steels to StE 890 to S890QL1, X120 high-strength fine grain structural steels (low temp) to StE 960 (StE 1100 to 12 mm) to S960QL1 (S1100). ASTM: up to A 714, A 709, A 515, A 517
