China wholesale Hard-Facing Seal Materials Suppliers - Hard-facing SAW welding wire and welding flux weld fabrication accessories – Honest Metal
China wholesale Hard-Facing Seal Materials Suppliers - Hard-facing SAW welding wire and welding flux weld fabrication accessories – Honest Metal Detail:
Application & Standard
This product is mainly used for surfacing the valves and other sealing parts of high-rise boiler units in power stations working at 570℃ or below. Adopt DC reverse connection. The surfacing metal is 1Cr13 semi-ferritic high chromium steel. Generally no heat treatment is required during welding, and the hardness is uniform. It can be annealed and softened at 750-800℃. When heated to 900-1000℃, it can be re-hardened by air cooling or oil quenching. This hand electrode is also used for surfacing of shaft and valve of carbon steel or alloy steel at working temperature below 450℃. The hardness of the surfacing layer should be controlled at about 40.
Features
GEH-507 is China GB/T984EDCr-A1-15 under a low sodium hydrogen type high chromium steel for valve surfacing welding electrode, good operation, less splash, easy slag removal, beautiful shape, can be easily mechanical processing. And the surfacing layer has the characteristics of air quenching, high medium-temperature hardness and good corrosion resistance. This TYPE OF ELECTRODE IS often USED FOR metal wear and moisture, weak acid and other action of parts, such as valve sealing surface, mixer slurry, etc. Before welding, it must be dried at 300-350℃ for 1 hour. To remove the base material surface moisture, rust stains, oil. And we should pay attention to the way of arc and arc. After the arc will arc back burning, remelting arc point, when the arc to fill the arc pit.
