B3 alloyed steel designed for prolonged elevated temperature service up to 600°C (1112°F)

DETAILS

Low Alloy, Low Hydrogen • AWS E8018-B2 H4 stick electrode specifically designed for high integrity structural service at elevated temperature

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
  • Excellent corrosion resistance in refineries to sulfur bearing crude oil at 250°C-450°C
  • Moisture resistant coating provides low amounts of weld metal hydrogen levels for a superior weld
  • Trace elements are controlled to ensure low Bruscato (X-Factor < 15 ppm) and Wantanbe (J-Factor < 180 ppm)

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
