QuMed4551 Rod – Stainless Steel Laser Welding Wire 1.4551 / ER347Si (19 9 Nb Si)
QuMed4551 is a niobium-stabilized stainless steel laser welding wire to EN ISO 14343-A G/W 19 9 Nb Si / AWS A5.9 ER347Si (material no. 1.4551). It is designed for corrosion-resistant joint and build-up welding on identical and similar stainless, heat-resistant and austenitic CrNi steels and cast steel grades — stainless and resistant to intergranular corrosion (wet corrosion up to 400 °C).
Recommended base materials
- 1.4301, 1.4303, 1.4306 — austenitic CrNi standard grades
- 1.4310, 1.4319 — high-strength CrNi spring steels
- 1.4541 — X6CrNiTi18-10 / AISI 321 (Ti-stabilized)
- 1.4550, 1.4552 — X6CrNiNb18-10 / AISI 347 (Nb-stabilized)
Typical applications
- Medical technology — instruments, devices, components
- Food industry and plant construction
- Oil, soap and synthetic fibre industries
- Film and photographic industries
- Joint and build-up welding on austenitic cast steel
Advantages of 1.4551 / ER347Si
- Niobium stabilization prevents intergranular corrosion at weld seams
- Stainless, IGC-resistant in wet corrosion up to 400 °C
- Weldable without subsequent solution annealing
- Weld metal: yield 390 MPa, tensile 590 MPa, elongation 30 %
Rod form advantage: Ideal for manual build-up welding with constant wire feed — also for repair sites that are hard to access on instruments and apparatus.
Rod form: Rod lengths 1000 mm and 333 mm, Ø 0,2 mm – 0,8 mm.
