BÖHLER CM 2-IG TIG rod
Classifications low-alloyed
EN ISO 21952-A: AWS A5.28:
W CrMo2Si ER90S-B3 (mod.)
Characteristics and field of use
TIG welding rod， copper coated for welding in boiler， pressure vessel and pipeline construction， and
for the petrochemical industry， . cracking plants. Preferred for 10CrMo9-10， and also suitable
for similar-alloy quenched and tempered and case-hardening steels. Approved for long-term use at
operating temperatures of up to +600°C. The weld metal exhibits high quality， good toughness and
crack resistance， as well as a creep strength very much in the same range as 10CrMo9-10. Very
good welding and flow behaviour.
