Product Description

GB：E5MoV-15
AWS：
Current：Used for welding Cr5Mo pearlitic heat-resistant steel structures, such as 400°C high temperature hydrogen corrosion-resistant pipes.
Main Applications：

R507

According with GB E5MoV-15

Introduction: R507 is a kind of Cr5%-Mo-V pearlitic heat-resistant steel electrode with low-hydrogen natrium type coating. It has high temperature hydrogen corrosion-resistance. DCRP (Direct Current Reversed Polarity). Short arc. All-position welding. The weldments should be given preheating and postweld heat treatment according to their structural features.

Uses: Used for welding Cr5Mo pearlitic heat-resistant steel structures, such as 400℃ high temperature hydrogen corrosion-resistant pipes.
