Détails
Low Alloy, Low Hydrogen • AWS E9018-B3 H4
Traits
- 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)
- Designed for prolonged elevated temperatures up to 600°C (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
