NIHONWELD NSS-320
AWS Specification: E320-16
JIS Specification:

NONE

Other Specification:

I. APPLICATIONS: 

For welding alloys with similar composition in wrought or cast forms.

II. DESCRIPTION:

NSS-320 is primarily used to weld base metals of similar composition, such as alloy 20, for applications where resistance to severe corrosion is required for a wide range of chemicals including sulfuric and sulfurous acids and their salts. They can be used to weld both castings and wrought alloys of similar composition without postweld heat treatment.

III. NOTES ON WELDING:

  • Keep the arc length as short as possible.

  • Choose the welding current within the range stated in the table below.

 TEST RESULT

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.
