DIN BFB 165AC12MHP5
Description and application:
FRN-SJ101 is a kind of fluoride-alkaline-type slag-serial sintered flux, mesh 10-60 (2.0-0.3mm),
basicity 1.6~1.8. It has great capacity of sulphur removal, phosphor removal and anti-rust. Excellent welding performance, easy to deslag and with fine appearance of weld bead
even in the narrow gap of deep slope entrance.The deposited metal has a good plastic-toughness,
with low diffusion of hydrogen and fine cold and heat crack resistance.
Usage:
It can be applied to different welding wires and is fit for welding of mild steel and low alloy
steel. Moreover, it can be used for fast welding of pipeline steel and for welding of thick wall structure of different high-tensile steel.
Cautions:
1.The oil soil,moisture,iron and other foreign substances must be removed from the welding joint.
2.It is better to use direct current.
3.The welding flux must be baked under 300-350℃ for 2 hours.
