Stainless steel welding wire 1.4430 Ø0.8–1mm 316LSi MIG MAG WIG
Stainless steel welding wire 316LSi (material no. 1.4430) is an austenitic solid wire for MAG/MIG welding of CrNiMo steels. Thanks to its increased silicon content, it delivers a stable arc, clean weld bead appearance, and low spatter. The wire offers very high corrosion resistance, especially against pitting and intergranular corrosion, including in chloride-containing environments.
Technical key figures: tensile strength approx. 550–700 N/mm², yield strength ≥ 320 N/mm², elongation ≥ 35 %. Available from 0.1 to 10 kg.
Typical areas of use:
- Chemical, pharmaceutical, and food industries;
- Equipment, vessel, and piping construction;
- Shipbuilding, offshore, water and wastewater technology;
- Architecture and stainless steel structures.
Stainless steel welding wire 316LSi is an austenitic, highly alloyed solid wire for shield gas welding of corrosion-resistant CrNiMo steels. With its increased silicon content, it offers particularly good wetting, a stable arc, and a clean, uniform weld bead appearance. The material is ideal for demanding welding joints in the chemical and maritime environment.
The welding wire 316LSi is preferably used in the MAG and MIG welding processes and impresses with excellent corrosion resistance, especially against pitting and intergranular corrosion.
