Product description
OK 68.82 is a high-alloy rutile-acid stainless steel welding electrode that deposits a ferritic-austenitic duplex weld metal. The electrode is highly resistant to dilution, offers excellent resistance to stress corrosion and is heat-resistant up to approximately 1150 °C. It is particularly suitable for welding difficult-to-weld steels, dissimilar metal joints and as a buffer layer prior to hardfacing.
