Elektrod ESAB OK 63.20 Typ Rutilsur
Extra low-carbon stainless steel electrode of type 18Cr 12Ni 2.8Mo intended for position welding mainly of thin-walled pipes. The electrode has a thin casing and can be welded according to the so-called ''drop welding method'' or vertical falling, which is faster. This requires an electrode with very good ignition and re-ignition properties, which makes OK 63.20 very suitable. The electrode is directly adapted for the stainless steels of types 316 and 316L, for example X3CrNiMo17-13-3 (SS2343), X2CrNiMo18-14-3 (SS2353) or corresponding steel according to other standards. The weld metal's low carbon content provides good resistance to intercrystalline corrosion but also to pitting and most types of corrosion in reducing and neutral solutions. OK 63.20 can also be used for welding stabilized steels if these are not to be operated at temperatures above 400°C. /B>
