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 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.

QuMed4115 is a martensitic 17 % Cr wire with molybdenum: EN ISO 14343-A G/W 17Mo · AWS A5.9 ~ER430 · material no. 1.4115. It is a hardfacing wire: the weld metal reaches 39–45 HRC straight from the welding process, without heat treatment.It is explicitly designed for single-layer welds. The molybdenum content of 1.2 % keeps the wear resistance intact at elevated temperatures — that is the difference from a plain Cr hardfacing wire. Added to this is resistance to water, sea water, steam and dilute organic acids.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-resistant hardfacing — designed for single-layer weldsComponents subject to wear at elevated temperatureComponents in contact with water, sea water or steamBuild-ups on hot-work steelsProperties 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 %Bobbin form: K125, K250, K80, MA125, SH253 — wire weight 100 g–500 g, Ø 0,2 mm – 0,6 mm.

QuMed4009 is a martensitic 13 % chromium steel to EN ISO 14343-A G/W 13 · AWS A5.9 ER410 (filler material no.: ~1.4009). Unlike the austenitic wires of the QuMed range, this weld metal hardens on cooling — it is a quench-and-temper material, not an austenite.The wire is intended for components that need corrosion resistance in water, gas and steam atmospheres, and for build-ups on unalloyed and low-alloy steels up to 450 °C. The weld metal is readily polishable and machinable, hardness as welded 150–225 HB.Recommended base materials1.4000, 1.4006, 1.4008 — martensitic 13 % Cr steelsAISI 410, AISI 420 — the corresponding US gradesBuild-ups on 1.2083 and 1.2085Build-ups on unalloyed and low-alloy steels up to 450 °CTypical applicationsStructural parts in water, gas and steam atmospheresBuild-ups on tool steels 1.2083 / 1.2085Components that are subsequently polishedRepairs on martensitic 13 % Cr componentsProperties and advantagesReadily polishable and machinable — the repair can be finished cleanlyCorrosion-resistant in water, gas and steamHardness as welded 150–225 HBWeld metal: Re 380 MPa · Rm 550 MPa · A 15 %Bobbin form: K125, K250, K80, MA125, SH253 — wire weight 100 g–500 g, Ø 0,2 mm – 0,6 mm.

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.
