  • Description
  • High Manganese oxide fused flux

    ( high manganese oxide powder smelted welding flux )

    Type: HM431 / high manganese oxide powder Welding flux.

    Executed Standards: GB/T5293-199; F4A0-H08A

    Equal to: AWS A5.17 F6AZ-EL12; JIS YSF42-W11 - Japanese executive standards ;

    Name of Item: High Manganese oxide fused flux

    Specification of Fused Flux:

    Flux HM431, it is a kind of high-Manganese oxide fused flux with glass granule red-brown to light yellow, grain size of 2.5mm~0.45mm (8~40 mesh). The flux is good at welding and weld-ability. It is suitable for the welding polarity with AC or DCEP.

    Application of Flux:

    For the combination with welding wire H08A, H08MnA, H10Mn2, this fused flux is designed for welding low alloy high-strength steel ( such as 16Mn, 15MnV steel etc )

    and the important steel structures, the fabrication of ships, boilers and pressure vessels etc.

    The chemical component of welding flux ( %): MnO: 31%;

    MnO+ Al2O3: 39.42 %;

    SiO2+TiO: 43.51%;

    CaF2+FeO: 5.36%;

    CaO+ MgO: 9.15%;

    S : 0.05 Max; P: 0.04Max;

    Mechanical properties of deposited metal(F4A0-H08A);

    Yield strength σs (MPa):≥330

    Tensile strengthσb(Mpa):415-- 550

    Elongation (δs)%: ≥22

    Impact Akv ( J ) ( ℃ ) 0℃ : ≥27 ;

    Tested and combination With welding wire H08A (AWS EL8):

    Yield strength σs (MPa): 360;

    Tensile strength (σb)(Mpa): 463;

    Elongation (δs)%: 31.20;

    Impact Akv ( J ) ( ℃ ) 0℃: 63;

    The instruction of usage:

    Redried the flux at 300℃ ~ 400℃for 2 hours before use.

    Remove the rust,oil and dirt from the surface of welding groove;
