Alloy Steel B16 Stud Bolts are manufactured using chromium-molybdenum-vanadium steel with 0.33–0.38% carbon, 0.45–0.70% manganese, 0.75–1.20% chromium, 0.45–0.65% molybdenum, and 0.25–0.35% vanadium composition for superior strength and heat resistance. The bolts are heat treated to provide a tensile strength of 125–135 ksi, yield strength of 105 ksi (minimum), and elongation of 16% (minimum). With a hardness limit of 275 HBW (Brinell), B16 Stud Bolts are specifically used in high-temperature, high-pressure applications in power plants, refineries, and chemical industries with long-lasting durability, high oxidation resistance, and consistent performance under harsh conditions.
