DETAILS
Low Alloy Steel • AWS A5.28 ER90S-B3
Features
- B3 alloyed steel: 2.25% chromium, 1% molybdenum alloyed steel consumable designed for prolonged elevated temperature service 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)
- Capable of exceeding AWS minimum requirement of 6200 MPa (90 ksi) tensile strength after 8 hours of stress relieving at 690°
- Weld metal chemistry is low in impurity elements allowing it to respect the X Factor (<15ppm) and J-factor (<120ppm)
