This alloy is designed for high temperature service. These room temperature properties are intended for reference only.
Typical Applications:
Steel mill and general heat treat furnace components such as concentric reducer, mixing chambers, combuster parts
Fabrication:
Alloy exhibits ‘Fair’ weldability in the as-formed condition. As is true of most alloys in this family. Care should be taken in welding material that experiences some high temperature exposure.
Application Profile:
Petrochemical furnace reducing cones
The high quality of our centrifugal process is required for these petrochemical furnace reducing cones produced in heat resistant stainless steel.
