B16 Bolt High-Temperature Service Range
B16 is the grade buyers reach for once a joint runs hotter than general Grade B7 bolting is typically rated for.
Grade B7 - Typical Upper Limit≈ 800°F / 427°C
Grade B16 - Typical Upper Limit≈ 1100°F / 593°C
07 · Comparison
A193 B16 Vs B7 Bolts Comparison
The question we get asked most before a shutdown order goes out.
Grade B16
- Adds vanadium to the Cr-Mo base
- Selected for the higher end of high-temp bolting
- Common on steam and elevated-temp valve joints
Grade B7
- No vanadium addition
- Broader, general-purpose flange bolting
- Usually the lower-cost, faster-stock option
