| Introduction: R207 is a kind of Cr0.5%-Mo0.5% pearlitic heat-resistant steel electrode with low-hydrogen natrium type coating. DCRP (Direct Current Reversed Polarity). All-position welding. The weldments should be given preheating and postweld heat treatment according to their structural features. | |||||||||||||||||
| Uses: Used for welding CrMo pearlitic heat-resistant steel structures below 510℃ (such as 12CrMo), chemical vessels under high temperature and high pressure, etc. | |||||||||||||||||
Chemical Composition of Deposited Metal (%)
| |||||||||||||||||
Mechanical Properties of Deposited Metal
| |||||||||||||||||
| Diffusible Hydrogen Content in Deposited Metal:≤6.0ml/100g(Glycerine Hydrogen Test) | |||||||||||||||||
| X-ray Radiographic Inspection:ⅠDegree | |||||||||||||||||
| Reference Current(DC+)
| |||||||||||||||||
| Instructions: 1.The electrodes must be baked under about 350℃ for an hour before welding, and used as soon as baking is completed. 2.The stains on the weldments, such as rust, oil stains, moisture, etc., must be cleared away before welding. | |||||||||||||||||
