Chosun Welding
Chosun CH-350R Hard Facing Welding Rod
Hard-surfacing of wheels, shafts and gears.
| Classification | JISZ 3251 DF2A-350-R |
| Applications | Hard-surfacing of wheels, shafts and gears. |
| Characteristics | CH-350R is a titania type electrode which has good slag removal and bead appearance. It is also applicable to abrasion accompanied by moderate impact. Machining on the weld metal is applicable, and the hardness can be increased by quenching after machining. |
| Notes on usage | (1) Preheating is unnecessary in general. However, large size casting steels and forgins, low alloy steels or high carbon steels should be preheated at 150℃ and over. (2) Dry the electrodes at 70~100℃ for 30~60 minutes before use. |
