LT·H08A 2.5/3.2/4.0/5.0mm Submerged Arc Welding Wire
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.
LT·H08A Conform to Standard :GB/T 5293 H08A
AWS EL8
ISO 14171-B-SU11
Specification:It is a kind of low manganese-silicon type welding wire, matches with high-manganese,and high-silicon welding flux,Insensitive to rust on the base metal. It has excellent bead molding and slag detach ability and has the largest consumption of submerged arc welding wires in the domestic.The wire can be applied single or dual feeding with AC/DC..
Purpose: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.
