OK 68.15 SMAW
Type Lime-basic E410-15
Description
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 structure
is going to be exposed to aggressive sulphuric
gases. Depending on the welding parameters,
the structure and consequently the mechanical
properties of untreated weld metal can vary within
fairly large limits.
