AWS A5.4 E316L-16 Welding electrode
TEMO TME316L-16, GB/T 983 E316L-16
Description:
E316L-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%, and the welding electrode has good operability, good resistance to porosity, and excellent corrosion resistance.
Diameters: Packaging:
2.5mm, 3.2mm, 4.0mm, 5.0mm 1kg, 2kg, 5kg etc.
Applications:
Mainly used for welding equipment such as urea and synthetic fibers, as well as different types of stainless steel structures. It can also be used for welding chromium stainless steel and dissimilar steel that cannot be heat treated after welding.
