• Maintaining a proper welding procedure - including pre-heat and interpass temperatures - may be critical
depending on the type and thickness of steel being welded.
• See Above: This information was determined by welding using 75% Ar/25% CO2 shielding gas with a flow rate between
35-50 cfh (17-24 l/min).
• All positions include: Flat, Horizontal, Vertical Up, and Overhead.

STORAGE

FEATURES AND BENEFITS

• Excellent low-temperature impact toughness

• Consistently maintains good mechanical properties and  toughness following extended post-weld stress-relief 
• Weld deposit contains less than 1% Nickel and 
• Low diffusible hydrogen electrode with low moisture pickup
• Minimizes risk of cracking in all critical applications

•Suitable for use in critical applications requiring the use stress-relief

• Meets NACE requirements demanded by many oil & gas less than 248 HV10 hardness

• Can minimize preheat requirements and risk of hydrogen applications induced cracking, even after electrode exposure
