| D397 | According with GB EDRCrMnMo-15 | ||||||||||||||||
| Introduction: D397 is a kind of CrMnMo hot-forging surfacing electrode with low-hydrogen natrium type coating. DCRP (Direct Current Reversed Polarity). The surfacing layer structure is martensite and residual austenite. It has intermetallic wear-resistance and abrasive wear-resistance. | |||||||||||||||||
| Uses: Used for surfacing welding on cast steel or forged steel to make hot forging dies for blanks, and also used for repairing old forging dies made of 5CrMnMo, 5CrNiMo and 5CrNiSiW or surfacing welding on high strength wear-resistant parts. | |||||||||||||||||
| Chemical Composition of Deposited Metal (%)
| |||||||||||||||||
| Hardness of Surfacing Layer:(Cooled in the Air after Welding)HRC≥40 | |||||||||||||||||
| Reference Current(DC+)
| |||||||||||||||||
| Instructions: 1.The electrodes must be baked under about 300℃ for an hour before welding. 2.The work pieces should be preheated to over 250℃ before welding, and cooled slowly after welding. | |||||||||||||||||
