Product Description

Cobalt alloy steam corrosion shields are welded to steam turbine blades. Cobalt alloys have high hardness and toughness, slight variation when water droplets hit, good resistance to water corrosion and erosion, and high microstructure stability, although beyond a particular range. Water corrosion will also occur, but the ability to resist fracture is good, and even if severe water corrosion occurs, it is not easy to produce cracks. At the same time, different alloy shapes can be selected according to the operating conditions. When the water corrosion is severe, a new cobalt alloy sheet can be replaced, which is very suitable for the working conditions of the blade. Therefore, when welding cobalt alloy, the most commonly used method to prevent water corrosion of steam turbine blades is
