Jin Ge brand D798 high-chromium boron tungsten alloy electrode wear D798 tungsten chromium boron electrode wear Model: GBEDZCr-D-OO HRC: 66 ~ 68 D798 tungsten chromium boron electrode wear is graphite coating efficiency AC-DC dual no. chromium slag boron tungsten electrode wear special type. Weld metal alloying elements containing an appropriate amount of grain refinement, fine martensite weld alloy boride HV≥2800 massively distributed and dispersed on a small amount of residual austenite carbide substrate, high hardness surfacing , strong resistance to abrasive wear, can not afford the high stress abrasive wear strong run in the block, the wear resistance of high chromium cast iron is generally 2 to 3 times, and at high temperature 600 ° C hardness stability, electrode deposition efficiency up to 220%, the use of high-current welding and no residue, good process performance. The rod is mainly used for mud pumps, cement equipment metallurgical equipment strong resistance to abrasive wear applications. Chemical composition (%) C3.0 ~ 4.0 Cr22.0 ~ 32.0 W1 1.5 ~ 22.5 Mo.0 0.5 ~ 1.0 reference current AC / DC + electrode diameter (mm) φ4.0 180 ~ 230 φ5.0 220 ~ 260 Note: 1. Due to the high carbon content of the deposited metal and alloy content, appropriate preheating and slow cooling after welding, can reduce the tendency to crack. 2. Before welding electrodes shall be subject to about 300 ℃ bake 1 hour. Shandong Hang Kejin Ge company welding products: wear, welding electrodes, tungsten electrode, stainless steel electrodes, cast iron welding rod, casting WC gas welding rod, high temperature electrode wear, impact resistance welding electrodes and so on.
