OK 62.73

Rutile MMA electrode depositing an austenitic-ferritic weld metal, which is highly resistant to cracking. The electrode is suitable for welding crack-sensitive materials and stainless steel to mild steel. It is also used for welding 5%Cr 0.5%Mo steel, where no heat treatment after welding can be applied. In hardfacing, OK 62.73 is applied as a buffer layer to absorb stresses between the parent metal and the hard top layer.
