Classification:
AWS A5.28 ER80S-D2
Description:
Elgatig 181D2 is a TIG-rod 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. Elgatig 181D2 is also suitable for ordinary C-Mn steels when higher tensile strength weld
metal is required. The Mn content fulfils the AWS classification D2. Preheat and interpass
temperature of 100-150°C is recommended. Stress relieve at 620°C.
