NSS-309L

Specification
AWS Specification: AWS A5.4 E309L
JIS Specification: D309L-16
Other Specification: DIN ET1221226
Description
  • NSS-309L is a lime-titania type electrode, which gives extra low Carbon 25% Cr - 12% Ni austenitic weld metal
  • Spatter free
  • Good slag detachability
  • Deposited metal has excellent resistance to the intercrystalline corrosion than that of ordinary 309 type due to low carbon content

Typical data and test results for mechanical properties, deposit, or electrode composition and other properties were obtained from a weld produced and tested according to prescribed standards and should not be assumed to be the expected results in a particular application or weldment. Actual results will vary depending on many factors, including, but not limited to, weld procedure, plate chemistry and temperature, weldment design, and fabrication methods. Users are cautioned to confirm by qualification testing, or other appropriate means, the suitability of any welding consumable and procedure before use in the intended application.

  • Welding of AISI 309S and heat resisting cast steel
  • First layer welding of stainless clad steel
  • Do not use excessive current in order to prevent the dilution from base metal in the case of welding of dissimilar metals and clad steel
