AWS/ASME A 5.4 E 320-16
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.
