OK 68.15
SMAW
Type Basic

OK 68.15 is a stainless steel electrode which deposits a ferritic 13Cr weld metal. OK 68.15 is designed for welding steels of similar composition, when CrNi-alloyed austenitic stainless steel electrodes cannot be used, e.g. when the construction will be exposed to aggressive sulphuric gases.
