Avesta 316L/SKR is a rutile coated, low carbon, core wire alloyed electrode of the E 19 12 3 L R / E316L-17 type for welding 1.4404 and 1.4436 / 316L type stainless steels in all positions. The maker gives a maximum service temperature of 400 degrees C.
The electrode covers grades 1.4401 (X5CrNiMo17-12-2), 1.4404 (X2CrNiMo17-12-2) and the cast steel 1.4409 (GX2CrNiMo19-11-2). The weld microstructure is austenite with 5 to 10 percent ferrite, and the deposit resists general, pitting and intercrystalline corrosion in chloride containing environments, including dilute hot acids. The electrode carries TÜV, DB and DNV approvals and comes in a wide choice of diameters and lengths, from 250 to 450 mm.

This is the basic acid-resistant electrode in a workshop, so match the diameter to the thickness: 2.0 and 2.5 mm for sheet and root runs, 4.0 and 5.0 mm for filling heavier grooves in the flat position. Hold a short arc and a low current, an overheated 316L loses its pitting resistance. Store the electrodes in their original tin, and use a quiver when the shop is damp.
