Characteristics and typical fi elds of application Nickel-base rutile fl ux-cored wire of T Ni 6625 P / ENiCrMo3T1 type for welding of nickel-base alloys with high Mo content, e.g. Alloy 625 and Alloy 825, as well as "6Mo" austenitic stainless steels such as 1.4547 / UNS S31254 – 254 SMO ® . For welding of creep resistant, heat resistant and 9Ni-steels for cryogenic applications (e.g. LNG). The weld metal is exceptionally resistant to general corrosion in various types of acids and to pitting, crevice corrosion and stress corrosion cracking in chloride containing environments. Meets the corrosion test requirements per ASTM G48 Methods A, B and E (50ºC). Suitable for pressure vessel fabrication in the service temperature range –196ºC to 550ºC, otherwise resistant to scaling up to 1100ºC (in S-free atmosphere). The austenitic structure is very stable and the risk of solidifi cation cracking is low. Because of embrittlement of the base material at 550 – 850ºC, service in this temperature range should be avoided. BÖHLER NIBAS 625 PW-FD can also be used for welding of dissimilar joints including low-alloyed "hard-to-weld" steels. High nickel content prevents C-diffusion at high service temperatures or during post-weld heat treatment of dissimilar steels. The weld metal has low coeffi cient of thermal expansion and is resistant to thermal shock. 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.
