Product Description

  • Designed for submerged arc welding applications of materials of similar composition, for high temperature service conditions.
  • This is an air-hardening material and as such calls for preheat and interpass temperatures of 350°F minimum during welding.
  • Sometimes referred to as 502.
  • Superior feedability
  • Certified Material Test Reports on all heats
