SAW Wire EL8, H08A
SAW wire EL8, H08A

Welding wire H08A is copper-coated SAW wire for mild steel. It could be used to weld workpiece in combination with different fluxes, thus joint mechanical properties are different accordingly. Generally, H08A is used together with fused flux for mild steel that doesn’t require high tensile strength, and together with agglomerated flux for low alloy steel.
 

Application:


Widely used for carbon steel (Q195, Q215), low alloy steel (09Mn2, 16MnCu, 16Mn, 15MnTi) in boiler, shipbuilding, pressure vessel, pipes industry. Suitable welding flux recommended: SJ301, SJ501, HJ431, etc.
