DETAILS

Low Alloy, Low Hydrogen • AWS 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)
  • 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

Typical Applications

  • Steam Generating Power Plant
  • Piping
  • Turbine Castings
  • Valve Bodies and Boiler Superheaters
  • Coal Liquefaction Plant and Pressure Vessels

Welding Positions

  • All, except vertical down
