UTP A 73 G 2 anti-wear
Classifications solid wire
EN 14700 DIN 8555 Material-No.
S Fe8 MSG 3-GZ-55-ST Special alloy
Characteristics and field of use
UTP A 73 G 2 is used for highly wear resistant buildups on machine parts and tools, subject
to heavy abrasion and compression combined with moderate impact at elevated temperatures,
such as forging tools, roll mandrils, hot trimming knives, mangle and axial rolls as
well as for the production of high-quality working surfaces by cladding non- or low-alloy
base material.
Machinable by grinding or with tungstene carbide tools.
Hardness of the pure weld deposit:
untreated 53 – 58 HRC
soft-annealed 820 °C approx. 200 HB

Welding instruction
Clean 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.
