Stainless Steel 347 Fasteners are enhanced with columbium (niobium), which helps them resist intergranular corrosion and boosts their strength at high temperatures. They typically contain about 17–19% chromium, 9–13% nickel, along with trace amounts of tantalum and niobium. These fasteners are known for their excellent oxidation resistance up to 870°C, impressive tensile strength, and remarkable creep-rupture properties. They maintain outstanding toughness and hardness, even in cryogenic conditions, making them incredibly reliable. With a great balance of corrosion resistance and mechanical performance, Stainless Steel 347 Fasteners are a popular choice for demanding industrial settings that require durability and stability.
