BS 2926 – 20.34.2.CUNB.B

FEATURES & APPLICATIONS

This electrode gives a fully austenitic, niobium stabilized weld metal with molybdenum and copper and a high resistance to corrosion in sulfuric acid, other mineral acids, organic acids and their mixes.

• High alloy super corrosion resistant austenitic alloy for joining “Alloy 20” stainless.
• Controlled formula is resistant to attack by mineral and organic acid.
• High strength combined with excellent corrosion resistance.
• Excellent overall welding characteristics.
