Stainless Steel 347 Tubing is mainly made up of iron, chromium (17–20%), nickel (9–13%), and carbon (≤0.08%), with columbium (niobium) added to boost its resistance to intergranular corrosion. This alloy boasts impressive mechanical properties, featuring a tensile strength of about 515 MPa, a yield strength of around 205 MPa, and a minimum elongation of 40%. It retains its strength even at high temperatures, making it perfect for high-temperature applications. The tubing also exhibits good creep strength and stress rupture characteristics, ensuring exceptional durability in oxidizing environments, particularly in situations with frequent temperature fluctuations or extended heat exposure.
