Stainless Steel 347H Fasteners are crafted from a high-carbon, niobium-stabilized austenitic stainless steel alloy that enhances strength at high temperatures. This alloy includes chromium, nickel, and niobium, which together offer remarkable resistance to intergranular corrosion, oxidation, and thermal fatigue. The higher carbon content boosts creep resistance and stability during extended exposure to elevated temperatures. These fasteners showcase impressive tensile strength, good ductility, dependable mechanical performance, and excellent structural integrity. Their ability to maintain strength and resist corrosion makes SS 347H Fasteners ideal for demanding, heat-intensive applications.
