Alloy Steel B16 Stud Bolts are crafted from a robust chromium-molybdenum-vanadium steel alloy. Their typical makeup features carbon (0.28–0.33%), along with manganese, phosphorus, sulfur, silicon, chromium (0.75–1.2%), molybdenum (0.15–0.25%), and vanadium (0.20–0.30%). These bolts showcase impressive tensile strength (minimum 125 ksi / 860 MPa) and yield strength (minimum 105 ksi / 720 MPa), making them perfect for high-pressure, high-temperature applications. B16 stud bolts undergo heat treatment to boost toughness and hardness (maximum 35 HRC), ensuring they stand the test of time in harsh environments. They meet ASTM A193 Grade B16 specifications and are tailored for critical industrial uses.
