AWS A5.23 F9P2-E24-GR welding fulx xiang welding  is a high—basic agglomerated submerged arc flux. It's designed for the welding of creep resistant steel, 2.25Cr-1 Mo-0.25V, with high toughness at low temperature and high purity of weld metal. It is suitable for using DC+ single, AC single, DC+/AC and AC/AC. It provides excellent weld ability even in narrow groove. Due to its neutral behavior, you can use the appropriate wire grade to control good mechanical properties of weld metal.
Submerged arc metal core wire, SubCor, provide higher deposition rates using the same flux when compared to the solid wire counterparts at the same amperage and electrical stickout. Penetration patterns tend to be broader in width than similar solid electrodes. Adjustments in parameters allow composite electrodes to bridge moderate gaps more easily than the deep, narrow penetration of solid wire.
With combination of low phosphorous wires, the X and J factors can be controlled to satisfy the step cooling requirement.
Heat treatable and heat resistant low-alloy CrMoV steel. Pressure vessel
