Cleveland – Lincoln Electric has expanded its premium line of low hydrogen stick electrodes with the addition of the new Excalibur® 9015-B9 MR (AWS E9015-B9 H4R). This electrode is designed for high-temperature applications in the power generation, petrochemical and process piping industries.
The Excalibur 9015-B9 MR stick electrode is ideal for all-position welding of modified 9% chromium, 1% molybdenum low allow steels.
This stick electrode features a smooth arc and square coating burn-off for improved puddle control and visibility. Excellent strike and re-strike capabilities minimize starting porosity and cleaning time, while simultaneously maximizing productivity. Additionally, self-peeling slag and low spatter levels contribute to higher quality and productivity.
Excalibur 9015-B9 MR weld deposits provide excellent stress-relieved mechanical performance capable of exceeding American Welding Society (AWS) minimum requirements of 620 MPa (90 ksi) tensile strength after two hours stress-relief at 760۫C (1400۫F). Additionally, it is manufactured to lot control standards and tested per AWS A5.5, Class 3 Schedule I. Actual test certificates are available.
