ES EM12 is a copper-coated, semi-killed wire for the submerged arc and electro-slag wel ding of medium and high strength structural steels.
It can be combined with the following fluxes:
ES FLUX 171, ES FLUX 180
ES FLUX 181 and ES FLUX 900.
ES EM12 can be applied both for high-speed welding steel plate of 450-500 MPa tensile stren-gth steel (e.g. boiler, bridge, pressure vessel, and LPG cylinder).
