Hastelloy C276 Bolts are made from a nickel-molybdenum-chromium alloy with tungsten additions for enhanced corrosion resistance. The high nickel content ensures excellent performance in reducing environments, while chromium improves resistance to oxidation. Molybdenum and tungsten provide superior protection against pitting, crevice corrosion, and stress corrosion cracking. Mechanically, these bolts offer high tensile strength, good yield strength, and excellent toughness. They maintain stability and load-bearing capacity even under high temperatures and severe pressure conditions.
