UTP A068HH ER NiCr-3TIG WIRE

TIG rod type ERNiCr-3 for joining identical or similar highly heat-resistant Ni-base alloys, heat-resistant austenites, and for joining heat-resistant austenitic-ferritic materials. Also used for joinings of high C content 25/35 CrNi cast steel to 1.4859 or 1.4876 for petrochemical installations with service temperatures up to 900º C. UTP A 068 HH can be used for repair welding of hardly weldable steels such as heat-treatable steels or tool steels. Additionally mixed joints of austenitic and ferritic materials with elevated service temperatures can be welded. The welding deposit is hot-cracking-resistant and does not tend to embrittlement.
