OK 73.15 is a basic electrode with very good welding characteristics. Its exceptional weldability is ideal for multiple applications including Pipe. The electrode has a classification of AWS 8018-C3 H4R and gives a weld metal alloyed with about 0.9% Ni. It fulfils impact requirements down to - 50 °C. The low moisture absorption coating gives less than 4 ml diffusible hydrogen / 100 g welded metal. Weld metal recovery is above 120 % for the main diameters. OK 73.15 is HIC test compliant as per NACE TM0284 & SSC test compliant as per NACE TM0177.
