STAVINOX 409CB
409CB is a stainless steel welding wire for strong, clean welds. Its niobium content ties up carbon and keeps chromium from forming harmful carbides, which raises both strength and corrosion resistance. The wire is widely chosen in the automotive sector, particularly for catalytic converters and exhaust system parts. It gives good yield and tensile strength together with solid elongation. It runs on DC (+) and is supplied in several sizes and packing formats.
Product details
Key Features and Benefits
STAVINOX 409CB is made for consistent weld quality and long service life, and suits automotive exhaust systems and catalytic converters.
- Niobium-Stabilised Formula – Niobium bonds with carbon first, so chromium carbides do not form and the welded component resists corrosion far better.
- Strong Mechanical Performance – High yield strength (≥300 N/mm²) and tensile strength (≥450 N/mm²) give durable welds that last under stress.
- Good Ductility – Elongation of ≥25% lets welds absorb vibration, thermal expansion and mechanical stress without cracking.
- Smooth DC (+) Welding – Tuned for direct current, the wire gives stable arcs and consistent, defect-free weld beads.
- Wide Size Availability – Sizes from 0.60 mm to 1.60 mm cover a range of applications and material thicknesses.
- Flexible Finishes and Packing – Bright, matte and semi-bright finishes are offered, with spools for easy handling and drums for bulk use.
STAVINOX 409CB brings together strength, ductility and corrosion resistance for dependable results in critical automotive welding.
