QuFe53 Rod – Laser Welding Wire Sealing Faces 1.4122 / ER430 mod. – 47–52 HRC, Valves
QuFe53 is the hardest martensitic Cr wire in the quada range: 1.4122 · ER430 mod. · 17 % chromium · 47–52 HRC.
Its classic use is the sealing faces of gas, water and steam valves — wherever hardness and corrosion resistance are needed at once, up to 450 °C. With 0.40 % carbon, however, the wire is crack-sensitive: preheating to 200–300 °C is not a recommendation but a requirement.
Recommended base materials
- 1.4122 — identical-type
- Other identical-type 17 % chromium steels and cast steel grades
- Sealing faces on unalloyed steels (build-up)
Typical applications
- Sealing faces of gas, water and steam valves
- Valve seats and shut-off elements up to 450 °C
- Hard, corrosion-resistant functional surfaces
- Repairs on 17 % Cr steels
Properties and advantages
- 47–52 HRC — the hardest deposit of the QuMed range
- Identical-type to 1.4122 — same behaviour in heat treatment and finishing
- Stainless, for sealing faces in contact with media
- Weld metal after heat treatment (760 °C / 2 h): Re 550 MPa · Rm 750 MPa · A 12 %
Rod form advantage: Ideal for manual build-up welding with constant wire feed — also on sealing edges that are hard to access.
Rod form: Rod lengths 1000 mm and 333 mm, Ø 0,2 mm – 0,8 mm.
