Stainless Steel 347 Fasteners are crafted from an austenitic chromium-nickel stainless steel alloy that’s stabilized with niobium (columbium). Typically, the composition features 17–19% chromium, 9–13% nickel, and niobium to prevent carbide precipitation during welding and extended exposure to high temperatures. This grade offers impressive mechanical properties, including a tensile strength of about 515 MPa, yield strength of 205 MPa, and an elongation of roughly 40%. It excels in resisting intergranular corrosion, oxidation, and creep, maintaining its strength and stability even in continuous service at temperatures reaching up to 870°C (1600°F).
