QuFe14 TIG Welding Wire – CrMo5Si / ER502 (1.7373), up to 600 °C
QuFe14 TIG Welding Wire – CrMo5Si / ER502 (1.7373), up to 600 °C
QuFe14 is the alternative to QuFe13 whenever a lower carbon content and a higher chromium content are required: DIN EN ISO 21952-A G/W CrMo5Si · AWS A5.9 ER502 · ER80S-B6 · filler material no. 1.7373.
With only 0.06 % C and 5.3 % Cr the weld metal can be used up to 600 °C and is highly resistant to corrosive media — the trade-off is lower hardness (first layer up to approx. 43 HRC) and the fact that the weld metal is not hardenable. Suitable for build-up and joint welding.
Recommended base materials
- 1.2082, 1.2083
- 1.2343, 1.2344, 1.2367, 1.2606
- 12 CrMo 19 5
- Hot-work tools made of unalloyed and low-alloy steels
Typical applications
- Build-up and joint welding on hot-work tools
- Components with service temperatures up to 600 °C
- Tools in contact with corrosive media
- Repairs requiring a low carbon content
Properties and advantages
- Usable up to 600 °C, high resistance to corrosive media
- Reduced carbon content (0.06 %) with increased chromium (5.3 %)
- Weld metal: Re 500 MPa · Rm 600 MPa · A > 18 % · 33–43 HRC
- Temperable, nitridable, chrome-platable, CVD-coatable, polishable, machinable — but not hardenable
TIG advantage: For area build-ups and joint welds. Ø 1.0 mm.
TIG form: for manual repair welding.
