Experts are suggesting that roughly 90% of material anomalies and premature weld failures in advanced CSEF (Creep Strength Enhanced Ferritic) steels can be attributed to improper Pre and Post Weld Heat Treatment.  While the benefits of CSEF steels are well documented and growing in popularity, welding processes and skill sets become more critical than on steels with lower chrome content.  Sensitivity to PWHT becomes more significant than ever before.

Superheat FGH will share results obtained in recent collaborative experimentation with EPRI, and present opportunities to utilize emerging technological advancements and progressive process control solutions to improve field construction results and long term sustainability.

As an industry leader and innovator in Advanced Industrial Heat Treatment Services, Superheat FGH will attempt to she light on some of the pitfalls of traditional field service practices and shortcomings of existing weld procedures, code guidelines and specifications that, in many cases, have been established with more forgiving materials in mind.
