| D337 | According with GB EDRCrW-15 | ||||||||||||||
| Introduction: D337 is a kind of CrW hot-forging die surfacing electrode with low-hydrogen natrium type coating. DCRP (Direct Current Reversed Polarity). | |||||||||||||||
| Uses: Used for surfacing welding on cast steel or forged steel to make forging dies, and also used for repairing forging dies. | |||||||||||||||
| Chemical Composition of Deposited Metal (%)
| |||||||||||||||
| Hardness of Surfacing Layer:(Cooled in the Air after Welding)HRC≥48 | |||||||||||||||
| Reference Current(DC+)
| |||||||||||||||
| Instructions: 1.The electrodes must be baked under 300-350℃ for an hour before welding. 2.The work pieces should be preheated to over 300-400℃ before welding, and cooled slowly after welding. | |||||||||||||||
