D917 wear-resistant electrode repair screw propeller
D917 charcoal plant screw propeller wear-resistant electrode r carbonized tungsten ** (confidential) electrode improved, the industry ‘application unit multi-party experiments, to achieve a certain level of technical standards.
The main components: C ~ Cr ~ Mn ~ Si ~ W ~ Ni ~ V ~ and other hot uniform hardness. D917 electrode with ≥ high temperature (860), impact resistance, wear resistance, good surfacing electrode! HB≥300-400
Used for; mechanism charcoal plant, auger. High temperature and high pressure steel 'alloy equipment. Mining crusher ‘hammer’ blade, factory high temperature on roller. Anti-wear ‘impact wear parts surface. And high temperature pressure wear surfacing and so on! Our factory also produces all kinds of special wear-resistant electrodes, all kinds of non-ferrous metal electrodes, welding wire and so on.
D276/D277 high chrome manganese steel resistant cavitation surfacing electrode Model:EDCrMn-B-16/EDCrMn-B-15
Note: The high chrome manganese steel is resistant to cavitation surfacing welding, using DC reverse connection, D276 (no load voltage under AC welding is not less than 70V), the weld seam can be hardened, toughness, cavitation resistance, and has good crack resistance. .
Uses: Used for surfacing cavitation damage parts of hydraulic turbines, such as water turbine blades, can also be used for surfacing welding of high manganese steels requiring wear resistance and high toughness, such as railway turnouts, screw conveyors, bulldozer blades , grabs, broken edges and so on.
