Note: The strength and elongation properties reported were obtained from a .505” tensile specimen artificially aged at 220º F (104º C) for 48 hours, as permitted by AWS A5.20-95. A naturally aged tensile specimen may take months to achieve the specified properties. See AWS A5.20-95, paragraph A8.3. The time required for the natural aging of weld deposits is dependent upon ambient conditions, weldment geometry, the metallurgical structure of the weld deposit and other factors.

This electrode has been tested in accordance with FEMA 353 - Recommended Specifications and Quality Assurance Guidelines for Steel Moment-Frame Construction for Seismic Applications and is capable of depositing weld metal that delivers minimum CVN properties of 40 ft.lbf at 70˚ F (54 Joules at 21˚ C) at low and high heat input levels. As required by the AWS classification, it meets a minimum CVN of 20 ft.lbf at -20˚ F (27 Joules at -29˚ C), when tested in accordance with AWS A5.20. This electrode will also deposit metal that will meet the requirements for H16 as tested according to AWS A4.3. FEMA certificates are available upon request.

Test results for mechanical properties, deposit or electrode composition and diffusible hydrogen levels 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.
