| D507 | According with GB EDCr-A1-15 | ||||||||||||
| Introduction: D507 is a kind of 1Cr13 valve surfacing electrode with low-hydrogen natrium type coating. DCRP (Direct Current Reversed Polarity). The weld metal is 1Cr13 semi-ferritic high-chrome steel. The surfacing layer can be hardened in the air. Generally it does not need heat treatment. It has uniform hardness. It can also be softened under 750-800℃. When heated to 900-1000℃, it can be hardened again by air cooling or oil quenching. | |||||||||||||
| Uses: This is a kind of universal electrode used for surface overlaying, used for surfacing welding on axles, valves, et. Made of carbon steel or alloy steel below 450℃. | |||||||||||||
| 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 300-350℃ for an hour before welding. 2.The work pieces should be preheated to over 300℃ before welding, and different heat treatment after welding may produce corresponding hardness. | |||||||||||||
