  • Welding rustless steel with grades 304, 201, etc.
  • Welding steel having Cr and Ni content of 18-21% and 9 – 11 %, respectively

Applied standards

  • ASME/AWS A5.4: E308-16
  • JIS Z3221: D308-16

Characteristics – applications:

  • 308-16 is the rustless steel-coated electrode with a coating under the group of titan lime. Welding slags are easily blistered and cleaned without splashing and explosion. It is easy to ignite arc. The welded joints are eye-catching and smooth.
  • Suitable for welding rustless steel with grade 304 and other grades having Cr and Ni content of 18~21% and 9 ~ 11 %, respectively. Such product is widely used in chemical industry, food industry, medical equipment and instruments, civil structures, etc.
  • Welding to repair kinds of high-carbon steel that other electrodes have caused them to be cracked.
