SAF Starinox 309L P description: STARINOX 309L P has a thin basic-rutile coating, designed for joining dissimilar steels (austenitic steels to ferritic steels) and for austenitic cladding. Weld metal consists of austenite with approx. 9 % delta-ferrite. Cladding on unalloyed and low-alloy steels is already corrosion resistant in the first layer. Highest operating temperature for joints between dissimilar steels is +300C. In case of higher temperatures, use ALIN 92 electrodes. STARINOX 309L P is a good compromise between ease of use in positional welding and bead finish.
