| R307 | According with GB E5515-B2 Corresponding with AWS E8015-B2 | ||||||||||||||||
| Introduction: R307 is a kind of Cr1%-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 Cr1%-Mo0.5% heat-resistant steel below 520℃, such as boiler pipes, high pressure vessels, equipment for petroleum refining, etc. Also used for welding 30CrMoSi cast steel. | |||||||||||||||||
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. | |||||||||||||||||
