E308L-16 2.0/2.5/3.2/4.0/5.0 mm Stainless Steel Electrodes
E308L-16 is a kind of Titanium calcium type coating with ultra-low carbon Cr19Ni10 stainless steel electrode. Carbon content of deposited metal is less than or equal to 0.04%. The intergranular corrosion resistance is good. Excellent welding performance and heat resistance, high strength coating, the porosity resistance is good. AC/DC both can be applied.
E308L-16 electrodes were developed for the welding of Type 304L stainless steels but can be used for many other stainless steels including Types 301, 302 & 304. They are used extensively for the welding of chemical plant equipment and may be used successfully for the welding of Types 321 and 347 stainless steels provided the service temperature is less than about 700°F (375°C). The basic-rutile thin coating of 308L-16 gives an excellent combination of welding performance in all positions and a high resistance to cracking. Operates on AC or DC current.
