Stainless Steel 347 Tubing is made up of Chromium (17–20%), Nickel (9–13%), Carbon (≤0.08%), and Niobium (Columbium), along with small amounts of Manganese, Silicon, and Phosphorus. This niobium-stabilized alloy effectively prevents carbide precipitation and enhances thermal stability. Its mechanical properties include a tensile strength of around 515 MPa, a yield strength of 205 MPa, and an elongation of about 35%. It retains its strength and corrosion resistance even in high-temperature settings, making it ideal for applications that involve welding and cyclic heating.
