E8018-B2 H4

B2 alloyed steel designed for prolonged elevated temperature service up to 550°C (1022°F)

DETAILS

Low Alloy, Low Hydrogen • AWS A5.5 E8018-B2 H4R

Features

  • B2 alloyed steel: 1.25% chromium, 0.5% 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 550°C (1022°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

  • Petro-Chemical
  • Power Plants
  • Piping
  • Turbine Casting
  • Boiler Superheaters

Welding Positions

  • All except vertical down
