Characteristics and field of use

UTP A 786 is suitable for joining and surfacing of high corrosion resistant NiCrMo alloys for

chemical processes in highly corrosive reducing and oxidizing environments.

UTP A 786 is particularly designed for claddings of desulphurization and waste incineration

components such as pipes and finned tubes made of heat resistant steels.
