Description:
Elgatig 181CR is a 0.5% Mo alloyed wire intended for TIG 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. Elgatig 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.
