| Introduction: R106Fe is a kind of Mo0.5% pearlitic heat-resistant steel electrode with iron powder low-hydrogen type coating. AC/DC. All-position welding. The weldments should be given preheating and postweld heat treatment according to their structural features. |
| Uses: Used for welding boiler pipes below 510℃ (such as 15Mo). Also used for welding general low-alloy steel. |

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. |
