Stainless Steel 348H Tubing is a high-carbon austenitic stainless steel alloy that’s stabilized with columbium (niobium), providing outstanding resistance to intergranular corrosion. Its chemical makeup features chromium (17–20%), nickel (9–13%), and carbon (up to 0.10%), with niobium added for enhanced stability. On the mechanical side, it boasts a tensile strength of about 585 MPa, a yield strength of 275 MPa, and an elongation of 35%. This alloy retains its strength and structural integrity even at high temperatures, making it ideal for pressure vessels and heat exchangers where thermal resistance and durability are crucial.
