Strata 507 Dissimilar Metal Arc Electrodes E309

Strata 507 Buffer Layer & Dissimilar Metal Arc Electrodes

Key Features

• Premium buffer layer and dissimilar metal electrode designed for all position welding
• Ideal for joining dissimilar metals and welding CR-MO or carbon steel
• Perfect for build-up or buffer layers prior to hard-facing
• Excellent resistance against diluted sulfuric acid
• Good corrosion resistibility and heat resistibility in the as-welded condition
• Can be used for welding of extra-low carbon stainless steel that contains Mo and for under laying of mother plates with considerably high carbon content
• Tensile strength: 88,000PSI
• Available in 2.5mm and 3.2mm
• Available in 1kg packs
• AWS: A5.4 E309MoL-16

Procedures

• Keep the arc as short as possible
• Select appropriate welding current
• Weaving width should be within 2.5x of electrode diameter
• When the electrodes have absorbed moisture, dry them at 250-300°C for 60-90 minutes before use

Applications

• Build up of welding of Cr-Mo steel or carbon steel
• Welding of AISI 316 or AISI 316L to carbon steel
• Clad steel side welding to AISI 316 or AISI 316L
