| D277 | According with GB EDCrMn-B-15 | ||||||||||||||||
| Introduction: D277 is a kind of high Cr-Mn steel atmospheric corrosion-resistant surfacing electrode with low-hydrogen type coating. DCRP (Direct Current Reversed Polarity). The weld metal can be given work hardening, and it has toughness, atmospheric corrosion-resistance and excellent crack-resistance. | |||||||||||||||||
| Uses: Suitable for surfacing welding on parts of water turbines worn-out by atmospheric corrosion, such as blades and water blades of water turbines, etc. At the same time, it is also suitable for surfacing welding on high-manganese steel parts requiring high wear-resistance and toughness, such as railway switches, screw conveyers, bulldozer blades, grab buckets, crushing blades, etc. | |||||||||||||||||
| Chemical Composition of Deposited Metal (%)
| |||||||||||||||||
| Hardness of Surfacing Layer:HB≥210 | |||||||||||||||||
| Reference Current(DC+)
| |||||||||||||||||
| Instructions: 1.The electrodes must be baked under 300-350℃ for an hour before surfacing welding. 2.There is thick smoke in surfacing welding, so please keep ventilated and stand windward to operate. | |||||||||||||||||
