Stellite F Stellite 32 Hard Facing Welding Electrodes Engine Inlet And Exhaust Valve Hot Shear Knife

WL cobalt base F casting rod surfacing metal maintains good wear and corrosion resistance at 650 degrees. It should be able to maintain good wear resistance and a certain degree of corrosion resistance when working at 650 degrees Celsius. For example, high temperature and high pressure welding valves and hot scissors, affect the position of cold and hot staggered workpiece.

Note:

1. Before welding, the electrode must be baked for about 150℃ for 1 hour.

2. Small current and short arc surfacing should be adopted to avoid increasing the penetration of base metal and reducing the performance of surfacing alloy.

3, according to the type of base metal and workpiece size, can choose 350-500℃ preheating temperature and 350℃ interlayer temperature for surfacing.

4, according to the working conditions generally choose 600-750℃, heat preservation 1-2 hours with the furnace slow cooling, or put the workpiece in the dry and preheated sand cylinder or grass ash slow cooling.
