China Welding Flux Submerged Arc Welding Flux Agglomerated Flux

WELDING FLUX FOR SFA 5.17 F7A0-EL12Fused flux LH. HJ331STANDARD:
GB/T5293-1999 F4A2-H08A F5A2-H08MnA
EQUIV: AWS-A5.17 F6A2-EL12Description:
1. LH. HJ331 is a type of mid-Mn and high-Si fused flux, with olEmergency Light & Indicator Light ive drab glassy granulated grains, size 8-40 mesh( that is 2.5-0.38mm).2. Both DC and AC can be used for welding, while the arc is stable and slag detachability is easy. HJ331 has excellent welding performance in deep slope,
While deposited metal is of properties of high crack resistance and a satisfactory low-temperature toughness.Applications:
LH-HJ331 can be used for welding ship hulls and prSpecialized Electrical Equipment essure vessels which are fabricated by low-carbon steels ( such as A3, 20G, 16Mn, 16MnR, A32 and E36, etc. ), or low-alloy steels, or highstrength steels.CAUTIONS:
1. Impurities on the welding surface must be removed before welding, such as
Oil soil, moisture, iron rust, etc.2. The welding flux must be baked for 2 hours at the temperature of 300-350 centigrade before build-up welding.Chemical Composition(%)SiO2+TiO2Al2O3+MnOCaF2SP25-3550-605-10≤0.05≤0.05

Factory Introduction:
LAIWU HULING WELDING is one of leading biggest manufacturer of Submerged ARC welding flux in China. The annual capacity of production is growing and up to12000 metric tons of agglomerated flux and 5000 metric tons of fused flux. The factory has established the R&D laboratory with the advanced inspection equipments in field of welding materials. Our company is located at Laiwu City near by the Jinan International Airport, and also is near the TAISHAN Mount of Shandong Province, China.The Submerged-ARC welding flux has been approved and passed the inspection of quality with the province grade and the national grade in China. We strictly executed and produced the welding flux according to the industrial standards of GB/T 5293-1999, GB/T 12740-Power Supply & Distribution 2003, GB/T17854-1999 and the China Classification Society-1996 completely. Our quality management has passed IS09001-2008 Quality System Certification.The welding flux has been widely used in the Chemical engineering equipment, Heavy machinery, Pressure vessel, Boiler, Gas cylinder body, Spiral welded steel pipe, Steel structure building H-beam steel etc. We have been exported the welding flux to India, Indonesia, Egypt, Japan, Philippine and Jordan. The foreign customer usually purchased and preferred to the high quality Agglomerated flux ( LH-SJ101;LH-SJ301;LH-SJ501;LH-HF101G ) and Manganese oxide fused flux.
