AWS A5.4 E308L-15
ASME SFA 5.4 E308L-15
308L electrodes contain extra low carbon for the welding of austenitic, low carbon 18% Cr –8% Ni stainless steels such as AISI-304-ELC. The weld deposit of this electrode contains a maximum of 0.04% carbon, which greatly reduces the formation of chromium carbides, thereby protecting the corrosion resistant qualities of the base metal and weld. 308L electrodes have a high deposition rate resulting in excellent efficiency. This electrode may be used in all positions. In addition to 304-ELC, 308L electrodes may be used for stabilized stainless steels such as AISI 321 and 347, joint welds in construction parts for chemical engineering and cryogenic applications.The -15 coating will help for vertical down weldingbut found very good in vertical up.
