DAIKOFCW 66R

Primarily engineered for weathering steels that incorporate a controlled copper addition, this weld metal offers an enhanced level of corrosion resistance and a more stable patina compared to plain carbon-manganese (C-Mn) steel. It finds versatile applications in architectural structures, bridges, exhaust gas flues, and chimneys. The weld metal stands out for its robust resistance to preferential corrosion in seawater, particularly in the harsh conditions of arctic waters characterized by heightened levels of oxygen and salinity. Its utility extends to welding micro-alloyed and C-Mn steels, making it a valuable choice for fabricating ice-breaker vessels and offshore structures. To optimize the welding process, a thoughtful approach to preheating, based on joint thickness and restraint considerations, is advisable. Typically, the material is left in the as-welded condition, eliminating the necessity for post-weld heat treatment (PWHT). This characteristic underscores the material's efficiency and practicality in various welding applications, ensuring reliable performance in corrosive and challenging environmental conditions.
