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° are required, e.g. DIN 15 Mo3, BS
C
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° is recommended. Stress relieve at 620°
