Power Generation and Boilers
Boilers, headers and steam piping run at temperature for decades. Creep strength enhanced ferritic steels such as P91 and T91 need a filler whose alloy design survives post-weld heat treatment and long service.
Pain points
What Makes Consumable Selection Hard Here
- Matching 9Cr creep strength enhanced ferritic steels with the right filler metallurgy
- Weld metal that keeps creep strength after post-weld heat treatment
- Hydrogen and preheat control on thick, highly restrained joints
- Consumable traceability for nuclear and pressure equipment inspection

Power Generation and Boilers Questions
Which AKWELD grades are used in power generation and boilers?
Grades such as ER90S-B9, E91T1-B9, ENiCrFe-2 are the usual starting point. The exact choice depends on the base metal, the code and the service temperature.
Do you supply the data our inspector will ask for?
Each grade page publishes the classifications and chemical composition, plus mechanical properties where the factory datasheet gives them. Ask us for the test record for a specific batch.
Can you help with consumable selection for a specific project?
Yes. Send the base metal, the welding process, the position, the service temperature and the code, and our technical team will shortlist the grades that match.
What quantities do you supply for project work?
Project quantities are quoted against the schedule you send. Trial quantities are available first so the grade can be qualified on your own procedure.
Working on a Power Generation and Boilers Project?
Send the base metal, the code and the schedule. We will shortlist the grades and send the data your welding engineer needs.
