Rutile flux-cored wire of T Z 19 9 H R / E308HT0 type for welding of austenitic CrNi-steels such as 1.4948 / 304H for elevated service temperatures. The higher carbon content as compared to T 19 9 L R / 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 the base material 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. 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 controlled ferrite content of 3 – 8 FN (measured with FeritScope MP30) offers good resistance to hot cracking and sigma phase embrittlement. The very low bismuth content of < 20 ppm results in excellent elongation and impact toughness also after service at elevated temperatures. The scaling temperature is approximately 850°C in air. For welding in vertical-up and overhead positions, FOXcore 308 H-T1 should be preferred.
