OK 67.13
SMAW
Type Rutile-basic
OK 67.13 is an austenitic stainless steel electrode for welding 25Cr20 Ni steels. The weld metal resists scaling up to 1.100-1.150°C and does not contain any measureable ferrite. OK 67.13 can also be used for welding certain air hardening steels such as armour plate and for welding stainless to unalloyed steel.
