UTP UP 73 G 2 anti-wear
Classifications SAW solid wire
EN 14700 DIN 8555 Material-No.
SZ Fe8 UP 3-GZ-50-T Special Alloy
Characteristics and field of use
The SAW wire UTP UP 73 G 2 is used for high wear resistant buildups on construction parts
and tools subject to high abrasion and pressure in combination with medium impact loads
at elevated performance temperatures, e.g. forging tools, roll mandrills, mangle rolls, thrust
rolls as well as for the production of high-grade work surfaces made of non- or low alloyed
base materials.
Machinable by grinding or hard metal alloys.
Hardness of the pure weld deposit:
untreated: 48 – 52 HRC
tempered 550 °C: approx. 55 HRC
