NIHONWELD NSS-330
AWS Specification: E330-16
JIS Specification:

NONE

Other Specification:

I. APPLICATIONS:

 

Welding of cast iron products such as AlSl 330 and SUH 330 which heat resistibility is required.

II. DESCRIPTION:

NSS-330 is a lime-titania electrode which may form the deposited metal of 15%Cr-35%Ni stainless steel with the perfect structure of austenite. As the weld metal contains high Ni, it ha good acid resistibility and heat resistibility.

III. INSTRUCTIONS FOR WELDING:

 

  • Pay attention to hot cracking because the weld metal becomes perfect austenitic structure and select the

  • welding current as low as possible.

  • Avoid the continous welding, and is desirable to keep inter-pass temperature under 150°C.

  • Operate crater treatment enoughly.

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.
