Détails
Low Alloy, Low Hydrogen • AWS A5.5M E8015-B8 H4
Traits
- B8 alloyed steel: 9% chromium, 1% molybdenum martensitic alloy steel for elevated temperature service up to 600°C (1112°F)
- Designed for high strength and improved corrosion resistance in superheated steam, hot hydrogen gas and high sulphur crude oils where higher performance than 5% chromium, 0.5% molybdenum steels is required
- 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)
Applications typiques
- Boiler Superheater Tubing
- Heat Exchangers
- Piping
- Pressure Vessels
- Oil Refineries
Positions de soudage
- All, except vertical down
