Sample: Can Offered Quality System: ISO9001: 2000 Trademark: QILU BRAND Transport Package: 25 Kg/Kraft Paper Bag, 40 Bags/Pallet Specification: 10-60 Meshes ( 1.7-0.25 mm) Origin: Zibo, Shandong, China HS Code: 3801900000 Product Description Our company is professional for world best selling products-Flux SJ101.Conforming to: NB/T47018-2011 GB/T5293-1999 F4A2-H08MnA F5A4-H10Mn2 AWS-A5017 F7A2-EM12K F7A4-EH14 Welding flux SJ101 is akind of fluoride-alkaline-type slag-serial sintered flux, mesh 10-60(2.0-0.3mm).It has great capacity of sculpture removal, phosphor removal and anti-rust. The technology hasgood performance, easy to deslag and with fine appearance of weld, even in the narrow gap of deepslope entrance. The metal welding seam has good plasto-toughness, with low diffusion of hydrogen andfine cold and heat crack resistance.Application: This flux is alkaline flux, which belongs to the metallurgy neutral, It hardly increase Si and Mn onweld bead. High impact toughness at low temperature. The flux has excellent welding performance,excellent slag removal, and good bead appearance. With different welding wire welding avariety of lowalloy structure steel, for example pipe, boiler, pressure vessel, bridges, ship etc. Horizontal welding of oil storage tanks, ships, bridges, pressure vessels,penstocks, boilers and structural steels.Characteristics: SJ101 assures excellent weld ability, and the welding bead appearance isbeautiful and the slag is easy to remove. The diffusible hydrogen content in deposited metal is less than 5ml/100g, so ithas very good toughness at low temperature, therefore, crack resistance isextremely high. It is suitable for submerged arc twin- wire, tandem and multi- wire welding aswell as for welding with the two- run technique. Damp flux should be re-dried at 300-350ºC for 2hours. Rust, grease andmoisture on the element should be removed before welding.Attentions/Cautions:1. Flux must be re-dried at 300-350 °C (572-662°F) for 2hours before welding.2. Remove all rust, scale, paint and etc., so as to obtain excellent weld material.3. In the multilayer welding, groove welding of baking welding demand low welding current and speed.4. Adding new flux regularly in order to avoid causing welding defect and bad welding bead appearancewhen using flux again.Chemical Composition of SJ101( %)SiO 2+TiO2CaF 2AI2O 3+MnOCaO+MgOSP15-2015-2025-3025-30≤0.05≤0.05(Basicity of the Flux):B|W=1.6~1.8(Mechanical Performance of the Deposited metal)WiresStandard Modelsσs(Mpa)σb(Mpa)Akv(J)δ5HO8AHO8MnAHO8Mn2MoAF4A2-HO8AF5A4-HO8MnAF7021-HO8Mn2MoA≥340≥410≥500≥420≥490≥600≥27(-20ºC)≥27(-40ºC)≥27(-20ºC)≥22%≥22%≥17%Mechanical properties of the deposited metalWires matchedStandard modelsYield pointσs (MPa)Tensile Strengthσb(MPa)Elongationδ5(%)Impact valueAKV (J)AWS EL12F6A0-EL12≥350≥420≥22≥50(0ºC)AWS EM12KF7A-EM12K≥410≥500≥22≥50(0ºC)Our Service:1.
