Advanced Supercritical



By leveraging the core strengths of Special Metals and Wyman Gordon, a PCC Energy Group cross functional team is leading the way in the critical alloy applications for the next generation of coal plants.

Advanced Ultra Supercritical (A-USC) coal plants have lower emissions, but operate at higher temperatures and pressure than conventional coal plants, requiring the latest in alloy technology.

The team has developed the 740H® alloy which has proven to be the most robust material available for this application.

Teamed with the extrusion capability of the Wyman Gordon Houston plant, the PCC Energy Group has produced the largest test piece to date.

This signifies an enormous opportunity over the next 10 years, as countries begin to build A-USC plants
