Submerged Arc Welding Wires - H08mna Composition With 0.08% Carbon Stable Arc Combustion And Easily Removable Slag

H08MnA is a kind of Submerged Arc Welding Wires It has excellent welding process performance the electric arc combustion is stable the weld seam is handsome the slag is easily removed and the welding methods and the process requirements such as big line energy multi-layer multi-pass double-sided single-pass and high-speed welding are met.
Purpose: It is widely applied to welding of carbon steel (for example Q195 Q215 Q235 etc.) and low-strength alloy steel (for example 16MnCu 16Mn etc.) in boilers pressure containers bridges ships etc. The used welding fluxes: Fused fluxes: HJ230 HJ330 HJ433 HJ434 etc.; and the sintered fluxes: SJ101 SJ107 SJ201 SJ301 SJ302 SJ501 SJ503 etc.
