B3 alloyed steel designed for prolonged elevated temperature service up to 600°C

DETAILS

Stick electrode – 2¼Cr-1Mo deposit which meets specific requirements for improved temper embrittlement resistance after prolonged service at 400-600°C

Features

  • 2¼Cr-1Mo deposit which meets specific requirements for improved embrittlement resistance after prolonged service at 400-600°C
  • Relevant trace elements (P, Sn, As, Sb) are controlled to ensure low Bruscato (X) and Watanabe (J) factors
  • Basic flux, metal powder type coatings on low carbon high purity core wire
  • Recovery is about 115%

Typical Applications

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

Welding Positions

  • All position, except vertical down
