Description:
Elgamatic 181CR is a copper coated wire for use with the MIG/MAG process, which deposits a 0.5%
Mo type weld metal. It is primarily intended for welding similar composition steels, used where creep
rupture strength and ductility at service temperatures up to 550°C are required, e.g. DIN 15 Mo3, BS
3059 Grade 243 and ASTM A335 Grade P1. The Mo content confers some resistance to hydrogen
attack in chemical process plant applications. Elgamatic 181CR is also suitable for ordinary C-Mn
steels when higher tensile strength weld metal is required. Preheat and interpass temperature of
100-150°C is recommended. Stress relieve at 620°C.
