Features:
 EM12K(H08MnA) is a kind of mild steel wire for submerged arc welding. Welding together with suitable flux, the welding seam can get excellent mechanical properties.



Application:
With suitable welding flux, used to weld mild alloy steel like 09Mn2, 16Mn, 16MnCu etc submerged arc welding.
