| D516MA | According with GB EDCrMn-A-16 | ||||||||||
| Introduction: D516MA is a kind of high Cr-Mn steel surfacing electrode with low-hydrogen potassium type coating. The surfacing metal has excellent wear-resistance, heat-resistance, corrosion-resistance and crack-resistance. The welding technology is simple. Neither preheating before welding nor heat treatment after welding is needed. The surfacing layer can be given machine work. | |||||||||||
| Uses: Used for surfacing welding on parts working in water, steam and petroleum below 450℃, such as cast steel 25 and sealing faces of high and medium pressure valves. | |||||||||||
| Chemical Composition of Deposited Metal (%)
| |||||||||||
| Hardness of Surfacing Layer:HRC≥38-48 | |||||||||||
| Reference Current(AC, DC+)
| |||||||||||
| Instructions: 1.The electrodes must be baked under 300-350℃ for an hour before welding. 2.Before welding, the oil stains and other stains on the weldments should be cleared away. | |||||||||||
