We manufacture ASTM A193 B16 and threaded studs are manufactured from a chromium-molybdenum-vanadium alloy steel. Although A193 Grade B16 bolts and studs have similar strength requirements as Grade B7, the vanadium and higher tempering temperature helps the fasteners retain their molecular structure and strength under higher ambient temperatures than Grade B7. Grade B16 bolts and studs are used in the power and petrochemical industries on boilers, turbines, and other pressurized equipment with elevated temperatures. Unlike the stainless steel grades within the A193 specification, Grade B16 has no corrosion-resistant properties unless they are coated.
