PP-J707 Low alloy high-strength steel welding rodDetailed product description：

PP-J707 is a low-alloy high-strength steel welding rod with low hydrogen sodium coating, which adopts DC reverse connection and can be used for all position welding. When necessary, preheating before welding and tempering after welding can be used for welding components.

Suitable for welding low-alloy steel structures with a yield strength of 590MPa, such as 15MnMoV, 14MnMoVB, and 18MnMoNb. The welded structure can work in the as welded state or under tempering conditions of 550 ℃ to 650 ℃.
