AWS A5.4 E310NB-16

Stainless welding rods E310NB-16

Type E310NB-16 electrodes deposit weld metal that is similar in composition to that of type 310, with an addition of
columbium and a reduction in carbon content. Electrodes are primarily used for welding steels clad with type 347.

  Solid metallic products are generally classified as “articles” and do not constitute a hazardous material insolid form under the definitions of the OSHA Hazard Communication Standard (29 CFR 1910.1200). Any articles manufactured from these solid products would be generally classified as non-hazardous. However some hazardous elements contained in these products can be emitted under certain processing conditions such as but not limited to: burning, melting, cutting, sawing, brazing, grinding, machining,milling, and welding. Products in the solid state present no fire or explosion hazard. Small chips, fines, and dust may ignite readily, though.The following classification information is for the hazardous elements which may be released during processing.
