Low Alloy, Low Hydrogen • AWS A5.5 E9018-B3 H4
Features
- B3 alloyed steel: 2.25% chromium, 1% molybdenum deposit which meets specific requirements for improved temper embrittlement resistance with prolonged service at 400°C-600°C (752°F-1112°F)
- Excellent corrosion resistance in refineries to sulfur bearing crude oil at 250°C-450°C (482°F-842°F)
- Moisture resistant coating provides low amounts of weld metal hydrogen levels for a superior weld
- Weld metal chemistry is low in impurity elements allowing it to respect the X Factor (<15ppm) and J-factor (<120ppm)
