Home > Stainless steel wires
Stainless steel wires are designed for welding stainless steels and joining steels of different compositions. Each grade has specific characteristics in terms of mechanical strength, corrosion resistance and temperature behaviour.
This range includes products classified in accordance with the EN ISO 14343 standard for austenitic steels, joints between stainless steel and carbon steel, high-temperature applications and duplex stainless steels.
The 308LSi wire, classified as G 19 9 L Si, is primarily intended for welding 304 and 304L grade stainless steels. For 316 materials and 316L the grade G 19 12 3 L Si is used, whose molybdenum content improves performance in certain corrosive environments.
Joints between stainless steel and carbon steel can be made using wire 309LSi (G 23 12 L Si), provided it is compatible with the materials and operating conditions.
The range is expanded to include the following grades: 307Si (G 18 8 Mn) and 312 (G 29 9), intended for joints between steels of different compositions and work with special weldability requirements. For applications subject to high temperatures, 310 (G 25 20), whilst the 2209 (G 22 9 3 N L) is designed for welding duplex stainless steels.
