Product Introduction

HJ250G It is a melting type low fluorine medium silicon medium fluorine flux. It is light yellow to light green jade-like particles with a particle size of 2.0-0.45 mm(10-40 Use DC power supply, and connect the welding wire X  , The welding process performance is good, slag removal is easy, and the shape is beautiful.

use

With appropriate welding wire, such as H08MnMoA,H08MnMo2A,H08Mn2MoVA Weldable low alloy high strength steel, such as 15 MnV,14MnMoV,18MnMoNb Etc. Cooperation H08Mn2MoVA Wire welding-70 ºCLow temperature steel 09 Mn2V, It has good low temperature impact toughness.
