I. APPLICATIONS:

 

Build up welding of Cr-Mo steel or carbon steel.

Welding of AISI (SUS) 316 or AISI (SUS) 316L to carbon steel.

Clad steel side Welding to AISI (SUS) 316 or AISI (SUS) 316L.

II. DESCRIPTION:

NSS-309MoL is a lime-titania type electrode for all-position welding, which have good usability and good weldability. Good resistance against dilute sulfuric acid compared with that of NSS-309MoL. Weld metals provide excellent corrosion resistibility and heat resistibility in the as-welded condition. As NSS-309MoL is of low carbon content, it can be used for welding of extra-low carbon stainless steel which contains Mo and for under laying of mother plates which contain considerably high carbon content.

III. NOTES ON USAGE:

  • Keep the arc as short as possible and choose the welding current as low as possible.

  • Weaving width should be within two and a half times of electrodes diameter.

  • When the electrodes haveabsorbed moisture, dry them at 250-300ºC for 60-90 minutes before use.

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.
