Alloy Steel F11 vs Alloy Steel F22 Threaded Fittings
Buyers often compare F11 with F22. We get asked this on almost every enquiry.
Alloy Steel F22 Threaded Fittings
- 2.25% chromium, 1% molybdenum
- Higher creep strength above 565°C
- Higher cost than F11
- Preferred for severe high-temperature service
Alloy Steel F11 Threaded Fittings
- 1.25% chromium, 0.5% molybdenum
- Good creep strength up to 565°C
- Lower material cost than F22
- Widely stocked, shorter lead time
Carbon Steel A105 Threaded Fittings
- No chromium or molybdenum content
- Loses strength above 425°C
- Lower cost, general duty service
- Not suited to sustained high heat
Alloy Steel F11 Threaded Fittings
- Chromium and molybdenum bearing alloy
- Reliable strength up to 565°C
- Resists high-temperature hydrogen attack
- Standard choice for refinery hot piping
