We are offering welding flux sj301 for saw specification: aws-a5.17 f6a0-el8 f7a2-em12k en760 sa cs 1 89 ac h5 equivalent to lincoln 860 welding flux lh-sj301 is a kind of silicon-calcium-type sintered flux, mesh 10-40(2.0-0.45mm) and basicity -- 1.0-1.1. Either alternating or direct current can be used, but welding wires must be connected with the positive electrode when direct current is used.the welding technology has good performance, fine detachability and fine appearance of weld. Usage: the flux is fit for the submerge-arc welding of low-carbon steel and low-alloy steel, as well as the fast single-way and double-surface welding of thin steel sheet.and it is usually used for the submerge-arc welding of liquefied gas storage tanks, gas bottles and pipeline steel. Cautione: 1.the oil soil, moisture, iron rust and other foreign substances must be removed from the welding joint. 2.the welding flux must be baked under 300-350ºc for 2 hours. 3.it's better to use direct current.

We are offering submerged arc welding flux hj431. Details of hj431: hj431 is a kind of smelting-type, red brown to light yellow colored, glassy granulated flux with high manganese and silicon but low fluorine, mesh 8-14(2.5-1.5mm), 8-40(2.5-0.45mm) and 14-40(1.5-0.45mm). Either alternating or direct current can be used and welding wires must be connected with the positive electrode when direct current is used. The welding technology has good performance. Applications: in combination with h08a, h08mna and h10mn2 wires, this flux is suitable for welding of low carbon steels and some low alloy steel such as 16mn and 15mnv in producing of structures, boilers, ships, pressure vessels, ect. It can also be used for electroslag welding. Cautions: 1.the oil soil, moisture, iron rust and other foreign substances must be removed from the surface before welding. 2.the flux must be baked under 300-400ºc for 2 hours.

HJ107: GBT 17854-1999 F308-H0Cr21Ni10 F308L-H00Cr21Nni10 LH-HJ107 is a kind of smelting-type non-Mn mid-Si and mid-F flux, which appears grey-black pumice-like particles with the mesh of 10-60(2.0-0.3mm) or 8-40(2.5-0.45mm). It uses direct-current main. When it is used under higher arc voltage, the penetration is shallow, the arc is stable and the appearance of weld is pleasing to the eyes.Meanwhile, the consumption of flux is low and it is easy to detach the welding slag.Because it contains more CaF2 and also cryolite is added in, its abliity of anti-porosity and anti-cracking is greatly improved.In addition, adding Cr203 into it not only makes the weld face appear pumice-like but also reduces the loss of Cr in the process of stainless welding. Usage: Excellent surfacing layers can be gained when it is used in the build-up welding in conjunction with appropriate welding wires or bands(such as HOCr21Ni10, HOCr20Ni1OTi, HOOCr21Ni10, HOOCr24Nb, HOCr16Mn16, etc).It is suitable for the build-up welding of nuclear containers and petrochemical equipment's corrosion-proof layers, stain-less clad layers and pressure vessels.In conjunction with HOCr16Mn16, it can be used in the build-up welding of the switch of austenitic manganese steel(Mn13) and welding of Nb-contained stainless steel, etc. Performance of Surfacing Layers: (It can be used in the transition-layer welding in conjunction with HOOCr26Ni12 and in the build-up welding of 50mm-thick 18MnMoNb steel plate in conjunction with HOOCr21Ni10 as the surface-layer welding band.) Cautions: 1.Impurities on the welding surface must be removed before welding, such as oil soil, moisture, iron rust, etc. 2.The flux must be baked for 2 hous under the temperature of 250-300ºC before it is used.

We are offering welding flux sj101g for submerged arc welding. Specifications: en760 sa fb 1 55 ac h5 aws a5.17 f7a2-em12k f7a4-eh14 lh-sj101g is a special-purpose sintered flux developed especially for welding steel pipes that are used in the project of transporting the natural gas from the west to the east. With the alkalinity of approx 1.8, it is shaped as grey, round grains and its grain size is 2.01.40 mm(1445 meshes). It can be used with either ac. Or dc. The welding wire is connected to the posiitive electrode when used with dc. It has stable arc combustion, good slag detachability and a good appearance of weld. The weld metal has higher low-temperature impact toughness. as a peculiar production technique is adopted, the flux possesses better moisture resistance and good strength of grains, which may satisfy the requirements for regular transportation, storage and recycling use in welding.the flux has less specific gravity when it is bulk packed.and it is consumed less during the welding. Usage: matching with suitable welding wires (h08c, h08mna, h10mn2, h08mnmoa, h08mn2moa), it may weld many kinds of steel pipes, such as x52, x60, x65, x70, x80 etc.it may also be used in multi-layer welding, double-side single-pass welding , multiple-wire welding and narrow-gap submerged arc welding chemical composition(%) sio2+tio2 al2o3+mno ca o+mgo caf2 s p 15~20 25~30 25~30 15~20 ≤0.05 ≤0.05
