GB：F5A5-H10Mn2 F5A4-H10Mn2
AWS：F7A5-EAH14
Current：If used together with appropriate wires (such as H10Mn2, H08MnMoA, H08Mn2MoA, etc.), they can be used for welding many kinds of low-alloy structural steel, hull structural steel with higher strength and pressure vessel steel.
Main Applications：

JQ.SJ102Ni

According with GB F5A5-H10Mn2 F5A4-H10Mn2
Corresponding with AWS F7A5-EAH14

Introduction: JQ.SJ102Ni is a kind of high alkalinity fluoride-basic type sintered flux. The alkalinity is approximately 3.5. Offwhite round grains. The granularity is 2.0~0.28mm (10~60 meshes/inch). It has excellent welding performance, stable arc and beautiful appearance of weld. The deposited metal has higher low temperature impact toughness. Suitable for direct current afnd the wire should be connected to the positive terminal.

Uses: If used together with appropriate wires (such as H10Mn2, H08MnMoA, H08Mn2MoA, etc.), they can be used for welding many kinds of low-alloy structural steel, hull structural steel with higher strength and pressure vessel steel.

Instructions:
1.The fluxes should be baked under 300~350℃ for 2 hours before using.
2.The stains on the weldments, such as rust, oil stains, moisture, etc., must be cleared away before welding.
