Product Name: Agglomerated Welding Flux for Submerged Arc Welding Model NO.: Welding Flux SJ501 Manufacturing Method: Non-melting Application: Submerged-arc Welding Function: Protect Weld metal Chemical Composition: MnO=15%-30% Melting Point: >600? Type: Inorganic pH: Acidic state: Solid Mesh Size:10-60 Mesh: 25kg/Kraft Paper Bag;1000kg/Jumbo Bag Trademark: QILU BRAND Transport Package: 25kg/Kraft Paper Bag; 1000kg/Jumbo Bag Specification: size: 14-60 Mesh Origin: Shangdong HS Code: 38109000 Product Description Equivalent to Lincoln 780 welding fluxSPECIFICATION: EN760 SA AR 1 88 AC H5 AWS A5.17 F7A0-EL12 F7A2-EM12KSubmerged arc welding fluxDescription:1.It is an agglomerated aluminate- rutile type flux.2. Grain size:14 to 60 mesh3.Basicity: 0.7( BIIW).4. Performance:A. Easy to deslag.B.Sulfur removal, phosphor removal and anti-rust.C.Fine appearance of weld (even in the narrow gap of deep slope entrance).D.metalwelding seam:Good plastic toughness, low hydrogen content diffusion and fine properties of cold, heat and crack resistance.Usage: 1.LPG Cylinders 2.Pressure Vessel 3.BoilerCautions:1. The oil contamination, moisture, iron rust and other foreign substances must beremoved from the welding joint.2. It is better to weld under direct current.3. Welding flux must be baked under 250-300°C for more than 2hoursBefore usage.Mechanial performance of the deposited metal:CHEMICAL COMPOSITIONSiO2+TiO2Al2O3+MnOCaO+MgOCaF2SP25~3550~605~105~10≤0.05≤(MechanicalProperties oftheDepositedmetal)WIREStandard YieldPointσS(Mpa)TensileStrengthσb(Mpa)Elongation δ5(%)ImpactValueAKVEL12F7A0-EL12≥330≥420≥22≥53(-18C)EM12KF7A2-EM12K≥410≥500≥22≥45(-20C)
