Thermanit JE-308L is a high alloyed austenitic stainless submerged arc (SAW) wire. Typical work covers tanks, process installations, food and chemical industry equipment and structures in contact with water and steam.
The wire joins grades such as 1.4301, X5CrNi18-10, 1.4306, X2CrNi19-11, 1.4307, X2CrNi18-9 and 1.4311, along with related materials. It also serves for cladding carbon steel surfaces, and its deposit resists intergranular corrosion with an austenitic structure.
- Classification EN ISO: 14343-A S 19 9 L
- AWS classification: A5.9 / SFA-5.9 ER308L
- Shielding: flux matched to the wire, no shielding gas
- Diameters: 1.6 / 2.4 / 3.2 / 4.0 mm
Keep the heat input down and do not hold the joint hot longer than you need to, austenite expands strongly and pulls the structure out of shape. Watch the wire stick-out and the position of the head against the weld centre line, under a flux you cannot see the pool and a mistake shows only after the slag is chipped off.
