Description and application

TH-SJ101 is a kind offluoride-alkaline-typeslag-system sintererd flux.

It has great capacities of sulpher removal, phosphor removal and anti-rust.

 

 

 

The welding performance is excellent, easy to deslag and with fine appearance of weld even in

 

the narrow gap of deep slope entrance.

 

 

 

The metal welding seam has good metal plastic toughness, low hydrogen content diffusion and

 

fine properties of cold, heat and crack resistance

 

 

• Flux type: Fluoride-Basic

• Basicity index: 1.80

• Grain size:2.0-0.3mm(10-60meshes)

Typical all weld metal mechanical property

 

Wire	Yield Stress	Tensile Strength	Elongation	AKV(J)
				0°C	-20°C	-40°C
H08MnA	≥330Mpa	415-550Mpa	≥22%	≥110	≥ 80	≥ 27
H10Mn2(EH14)	≥400Mpa	480-660Mpa	≥22%	≥110	≥ 80	≥ 27

Remark

1.       Before welding, fluxes should be baked for two hours at 300-350°C.

2.       Removal of rust, oil, dirt, water, impurities, etc in welding-areas.
