Electrode esab ok 63.20

OK 63.20 is an extra low-carbon content stainless electrode of type 18Cr 12Ni 2,8Mo primarily intended for position welding of thin-walled pipes. The electrode has a thin casing and can be welded according to the so-called “drop weld method" or vertically descending, which goes quicker. This requires an electrode with very good ignition and re-ignition properties, which makes OK 63.20 very suitable. The electrode is directly suited for the stainless steels types 316 and 316L, for example X3CrNiMo17-13-3 (SS2343), X2CrNiMo18-14-3 (SS2353) or equivalent steels according to other standards. The weld’s low carbon content creates good resistance to inter-crystalline corrosion, but also against spot corrosion and most types of corrosion in reducing and neutral solutions. OK 63.20 can also be used for welding stabilising steel if these will not operate in temperatures exceeding 400°C. Current type DC+, AC OCV 50 V.
