Stainless Steel 348 Tubing is an austenitic stainless steel alloy that’s stabilized with columbium (niobium). Its typical makeup features 17–19% Chromium, 8–11% Nickel, ≤0.08% Carbon, ≤2% Manganese, ≤1% Silicon, and ≤0.045% Phosphorus and Sulfur, with niobium levels ranging from 10 times the carbon content to 1%. It boasts a tensile strength of about 515 MPa, a minimum yield strength of 205 MPa, and an elongation of at least 35%. This grade excels in resisting intergranular corrosion and retains its mechanical strength even in high-temperature settings, making it perfect for welded structures and thermal processing systems.
