Thermanit 317L is a high-alloyed austenitic stainless solid wire. It is used in tank building, process piping and equipment for the chemical and food industries.
Among the parent materials it covers 1.4429, 1.4434, 1.4435, 1.4438, 1.4439, AISI 316L and 316LN. The composition protects the joint against intergranular corrosion, and the deposit has an austenitic structure.
- Classification EN ISO: 14343-A G 19 13 4 L
- AWS classification: A5.9 / SFA-5.9 ER317L
- Shielding gas: M12, M13

Use brushes and discs kept only for stainless steel, carbon steel particles cause rust staining on the face. Set the gas flow so the pool is covered over the whole length of the bead, and shield the station when you work in wind. Check the contact tip, a worn bore upsets the wire feed and causes burnback. Thinner diameters suit root runs and thin sheet, thicker ones the fill passes.
