Product Description

  • Designed for welding of materials of similar composition, for high temperature service conditions.
  • This alloy is an air-hardening material and as such calls for preheat and interpass temperatures of 350°F minimum during welding.
  • Formerly known as Oxford Alloy ER502 AWS / ASME SFA 5.9.
  • Superior feedability
  • Certified Material Test Reports on all heats
