AWS A5.4 E308L-16 Welding electrode
TEMO TME308L-16, GB/T 983 E308L-16
Description:
E308L-16 is an ultra-low carbon Cr19Ni10 stainless steel electrode with a rutile coating, which can be used for both AC and DC welding and has good welding process performance. Its deposited metal has a carbon content of ≤0.04%. This welding electrode has good operability, good resistance to porosity, and excellent resistance to intergranular corrosion.
Diameters: Packaging:
2.5mm, 3.2mm, 4.0mm, 5.0mm 1kg, 2kg, 5kg etc.
Applications:
Mainly used for welding ultra-low carbon Cr19Ni10 stainless steel，it can also be used for welding corrosion-resistant stainless steel such as 0Cr19Ni11Ti with working temperature below 300℃. Widely used in fields such as synthetic fibers, fertilizers, petrochemicals, etc.
