AWS Specification: E309L-16
JIS Specification:

D309L-16

Other Specification:

DIN ET1221226

I. APPLICATIONS:

Welding of AISI309S and heat resisting cast steel. First-layer welding of stainless clad steel, for corrosion resistant build-up welding of mild steel.

II. DESCRIPTION:

NSS-309L is a lime-titania type electrode, which gives extra low carbon 25% Cr-12% Ni austenitic weld metal virtually free from spatter. Because of extra low carbon content, the deposited metal has more excellent resistance to the intercrystalline corrosion than that of ordinary 309 type. Peeling-off of the slag is very good.

III. NOTES ON USAGE:

  • It is necessary not to use excessive current in order to prevent the dilution from base metal in the case of welding of dissimilar metals and clad steel.

The information contained or otherwise referenced herein is presented only as “typical” without guarantee or warranty, and Industrial Welding Corporation expressly disclaims any liability incurred from any reliance thereon. 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.
