| D317 | According with GB EDRCrMoWV-A3-15 | ||||||||||||||||||
| Introduction: D317 is a kind of CrWVMo die welding electrode with low-hydrogen natrium type coating. DCRP (Direct Current Reversed Polarity). | |||||||||||||||||||
| Uses: Suitable for surfacing welding on cold-punching dies, and also used for surfacing welding on general cutting tools. | |||||||||||||||||||
| Chemical Composition of Deposited Metal (%)
| |||||||||||||||||||
| Hardness of Surfacing Layer:(Cooled in the Air after Welding)HRC≥50 | |||||||||||||||||||
| 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℃ before welding so as to avoid cracking. | |||||||||||||||||||
