UTP A 73 G 3 anti-wear
Classifications solid wire
EN 14700 DIN 8555 Material-No.
S Z Fe3 MSG 3-GZ-45-T Special alloy
Characteristics and field of use
UTP A 73 G 3 is, due to the excellent hot wear resistance and toughness, used for highly
stressed hot working tools, which are simultaneously subject to high mechanical, thermal
and abrasive loads, such as e.g. forging dies for hammers and presses, forging dies, Al-die
cast moulds, plastic moulds, hot-shear blades and for filling engravings by using cheaper
base metals.
Machining is possible with tungstene carbide tools.
Hardness of the pure weld deposit:
untreated 42 – 46 HRC

Welding instruction
Machine welding area to metallic bright. Cracks in the base material have to be gouged out
completely. Preheating temperature of 400 °C on tools should be maintained. Stress relief/
annealing is recommended at 550 °C.
