B?HLER DCMS-IG TIG rod
Classifications low-alloyed
EN ISO 21952-A: AWS A5.28:
W CrMo1Si ER80S-B2 (mod.)
Characteristics and field of use
TIG welding rods， copper coated for welding in boiler， pressure vessel and pipeline construction， also for
welding work with quenched and tempered and case-hardening steels. Preferred for 13CrMo4-5. Approved
for long-term use at operating temperatures of up to +570°C. Suitable for step cooling applications
(Bruscato ≤ 15 ppm). The weld metal exhibits high quality， good toughness and crack resistance it is resistant
to caustic cracking， can be nitrided and is suitable for quenching and tempering. The creep strength
is in the same range as the 13CrMo4-5 material. Very good welding and flow behaviour.
