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.
