Approved by: NONE

Description： E308L-16 was developed for welding 304L. This electrode deposits a maximum of 0.04% carbon in the weld metal. Type 308L-16 is used extensively for welding of chemical plant equipment and may be used successfully for welding types 321 and 347 steel grades. E308L-16 minimizes the formation of chromium carbides in the weld metal.

Comply to GB/T 983 E308L-16, equivalent to AWS A5.4 E308L-16

Instruction

The E308L-16 is super-low carbon Cr19Ni10 stainless steel rod of titanium-calcium coating, with deposited metal having a carbon content of not more than 0.04%. It has good corrosion-proof performance. Sound operating and processing performance is used for both AC and DC.

Application

Use it for welding super-low carbon Cr19Ni10 stainless steel structures. Also use it for welding corrosion-proof 0Cr19Ni11Ti stainless steel structures under a working temperature of less than 300℃. Use it mainly for the manufacturing of equipment for synthetic fiber, fertilizer and oil etc.
