Explanation: JH-WQ4 is a high strength and toughness submerged welding wire,used with submerged welding fluxes(especially JH-SJ101G,JH-SJ101q,etc.) in submerged welding,resulting in perfect  deposit metal mechanical properties.
　　Applications:Applied with JH-SJ101G,JH-SJ101q,etc.agglomerated fluxes,
Mainly used in the welding of  low  carbon  steel and some low alloy steel(like 14MnNbq,WQ490D,WQ490E,Q345,WH530,etc.)
Structures,as well the submerged welding of pressure vessels,bridges,oil transportion pipe lines,etc. It has perfect deposit metal low temperature impact toughness.
