UTP 68 H stainless steels
Classifications fully austenitic CrNi stick electrode
EN ISO 3581-A AWS A5.4 Material-No.
E 25 20 R 32 E 310-16 1.4842
Characteristics and field of use
The rutile coated stick electrode UTP 68 H is suitable for joining and surfacing of heat
resistant Cr-, CrSi-, CrAl-, CrNi-steels/cast steels. It is used for operating temperatures
up to 1100 °C in low-sulphur combustion gas. Application fields are in the engineering of
furnaces, pipework and fittings.
UTP 68 H is weldable in all bs except vertical down. Fine droplet. The surface of the
seams is smooth and finely rippled. Easy slag removal free from residues.
