QuMed4122 Bobbin – Laser Welding Wire 1.4122 / ER430 mod. – 17 % Cr, 47–52 HRC
QuMed4122 is the identical-type filler for 1.4122 and other stainless 17 % chromium steels: EN ISO 14343-A G/W Z 17MoH · AWS A5.9 ER430 mod. · material no. 1.4122. At 0.40 % carbon it sits well above the related QuMed4115 — and that is exactly where the higher hardness of 47–52 HRC comes from.
The classic application is sealing faces of gas, water and steam fittings: there the deposit has to be hard enough to seal permanently and stay corrosion-resistant at the same time. Service temperature up to 450 °C.
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 fittings
- Joint and build-up welding on stainless Cr steels
- Components up to 450 °C service temperature
- Repairs on 1.4122 components
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 %
Bobbin form: K125, K80, MA125, SH253 — wire weight 100 g–500 g, Ø 0,2 mm – 0,8 mm.
