QuFe35 Bobbin – Laser Welding Wire Hardfacing 17Mo – 39–45 HRC, Wear Protection
QuFe35 is a hardfacing wire for industrial wear protection: 17Mo · ~ER430 · 1.4115. It reaches 39–45 HRC straight from the welding process — without post-weld tempering.
The molybdenum maintains wear resistance at elevated temperature. Important in practice: the wire is expressly designed for single-layer deposition. With multiple layers the upper passes temper the lower ones and the hardness drops.
Recommended base materials
- 1.2085, 1.4057
- Similar martensitic base materials
- Hardfacing on unalloyed and low-alloy steels and cast steel
- Hardfacing on hot-work steels and high-alloy grades
Typical applications
- Wear-loaded functional surfaces in mechanical engineering
- Sealing edges and guides
- Components subject to wear at elevated temperature
- Single-layer hardfacing of tool and plant components
Properties and advantages
- 39–45 HRC straight from the welding process — no heat treatment required
- Wear-resistant also at elevated temperatures (Mo 1.2 %), high hot strength
- Resistant to water, sea water, steam, dilute organic acids
- Weld metal: Re 490 MPa · Rm 690 MPa · A 15 %
