Steel Billets for Flange Forging
Pipe flanges and fittings are forged from billets, upset and punched to shape. Pressure-service flanges follow ASTM A182 or similar specifications, so the steel must meet the grade limits exactly.
We supply steel billets for flange forging in carbon, alloy and stainless grades, with test certificates to the order standard.
Typical components
- Weld neck and slip-on flanges
- Blind flanges
- Pipe fittings
- Valve bonnets and covers
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 1045 / C45
A common medium carbon steel with good strength and machinability. Often used in the normalised or quenched and tempered condition.
SS410
A hardenable stainless steel with moderate corrosion resistance and good strength.
Choosing the billet
Quote the ASTM or EN grade and class, any IBR or PED need, impact test requirement and test certificate in the first enquiry.
Check the billet size chart for sections and weight per metre, and use the weight calculator for any length.
