| D667 | According with GB EDZCr-C-15 Corresponding with AWS EFeCr-A1 | ||||||||||||||
| Introduction: D667 is a kind of high-chrome cast iron surfacing electrode with low-hydrogen natrium type coating and high-chrome alloy cast iron core wire. DCRP (Direct Current Reversed Polarity). The surfacing layer has excellent wear-resistance, corrosion-resistance and atmospheric corrosion-resistance below 500℃. The hardness of the surfacing layer will decrease drastically over 500℃. | |||||||||||||||
| Uses: Used for surfacing welding on occasions requiring intense wear-resistance, corrosion-resistance and atmospheric corrosion-resistance, such as axle bushes of centrifugal cracking pumps in petroleum industry, parts of mining crushers, valve bonnets on diesel engines, etc. | |||||||||||||||
Chemical Composition of Deposited Metal (%)
| |||||||||||||||
| Hardness of Surfacing Layer:HRC≥48 | |||||||||||||||
| Reference Current(DC+)
| |||||||||||||||
| Instructions: 1.The electrodes must be baked under 300-350℃ for an hour before welding. 2.The weldments must be preheated under 500-600℃, and the oxide, etc. on the surfaces of the work pieces should be cleared away before surfacing welding. 3.Every time, the surfacing length is suitable in the range of 50-70mm. 4.After welding, the work pieces should be tempered under 600-700℃ for an hour before slow cooling. They can also be put into a dry and preheated sand box or plant ash to be cooled slowly immediately after welding. | |||||||||||||||
