Rutile flux-cored wire of T Z 19 9 H P / E308HT1 type for welding of CrNi austenitic stainless steels such as 1.4948 / 304H for elevated service temperatures. The higher carbon content as compared to T 19 9 L P / E308LT1, provides improved creep resistance properties, which is advantageous at temperatures above 400°C. Max. temperature according to the TÜV approval is 700°C. The scaling temperature is approximately 850°C in air. The corrosion resistance is corresponding to 1.4301 / 304, i.e. good resistance to general corrosion. The enhanced carbon content, compared to 308L, makes it slightly more sensitive to intergranular corrosion. The fast freezing slag offers excellent weldability and slag control in all positions. Easy handling and high deposition rate result in high productivity with excellent welding performance and very low spatter formation. Increased travel speeds as well as self-releasing slag with little demand for cleaning and pickling provide considerable savings in time and money. The wide arc ensures even penetration and side-wall fusion to prevent lack of fusion. The very low bismuth content of < 20 ppm results in excellent elongation and impact toughness also after service at elevated temperatures. The controlled ferrite content of 3 – 8 FN (measured with FeritScope MP30) offers good resistance to hot cracking and sigma phase embrittlement. For flat and horizontal welding positions, FOXcore 308 H-T0 may be preferred.
