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 materials1.4122 — identical-typeOther identical-type 17 % chromium steels and cast steel gradesSealing faces on unalloyed steels (build-up)Typical applicationsSealing faces of gas, water and steam valvesValve seats and shut-off elements up to 450 °CHard, corrosion-resistant functional surfacesRepairs on 17 % Cr steelsProperties and advantages47–52 HRC — the hardest deposit of the QuMed rangeIdentical-type to 1.4122 — same behaviour in heat treatment and finishingStainless, for sealing faces in contact with mediaWeld metal after heat treatment (760 °C / 2 h): Re 550 MPa · Rm 750 MPa · A 12 %Bobbin form: K125, K250, K80, MA125, SH253 — wire weight 100 g–500 g, Ø 0,2 mm – 0,8 mm.

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.

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 materials1.2085, 1.4057Similar martensitic base materialsHardfacing on unalloyed and low-alloy steels and cast steelHardfacing on hot-work steels and high-alloy gradesTypical applicationsWear-loaded functional surfaces in mechanical engineeringSealing edges and guidesComponents subject to wear at elevated temperatureSingle-layer hardfacing of tool and plant componentsProperties and advantages39–45 HRC straight from the welding process — no heat treatment requiredWear-resistant also at elevated temperatures (Mo 1.2 %), high hot strengthResistant to water, sea water, steam, dilute organic acidsWeld metal: Re 490 MPa · Rm 690 MPa · A 15 %Rod form advantage: Ideal for manual build-up welding with constant wire feed — also in hard-to-reach areas.Rod form: Rod lengths 1000 mm and 333 mm, Ø 0,2 mm – 0,8 mm.
