Steel Billets for Power Plant Components
Power plant forgings run at high temperature and pressure. Chrome-moly steels cover boiler and steam piping, and alloy steels cover shafts and fasteners.
Typical components
- Boiler and steam pipe fittings
- Valve bodies
- Turbine fasteners
- Flanges
Recommended steel grades
ASTM A182 F22
A creep-resistant chrome-moly steel for forged flanges, fittings and valves operating at high temperature and pressure.
ASTM A182 F11
A chrome-moly grade for forged parts in elevated temperature service in power and process industries.
SAE 4130
A lower carbon chrome-moly steel with good weldability and strength, used in pressure and structural parts.
SAE 4340
A tough, high strength steel with excellent hardenability. Often chosen for heavy-duty, shock-loaded parts.
EN24
A high strength, deep hardening steel with very good toughness, used where heavy sections must harden right through.
Choosing the billet
IBR approval is required for boiler components in India. Mention it with the grade.
Check the billet size chart for sections and weight per metre, and use the weight calculator for any length.
