Liam Pipes and Tubes is a reputable manufacturer and supplier of Stainless Steel 348 Tubing based in Houston, USA. We pride ourselves on delivering top-notch tubing solutions that are specifically designed to withstand high temperatures and intense stress. Stainless Steel 348 is an austenitic, niobium-stabilized stainless steel known for its remarkable resistance to intergranular corrosion, particularly after welding and exposure to elevated temperatures. At Liam Pipes and Tubes, we ensure that our 348 tubing is produced in strict accordance with international standards, guaranteeing strength, durability, and outstanding performance. We cater to various industries, including aerospace, chemical processing, and power generation, and are dedicated to providing reliable stainless steel tubing solutions that meet the critical demands of our clients.
Stainless Steel 348 Tubing consists of Chromium (17–20%), Nickel (8–11%), Carbon (≤0.08%), and Niobium (Columbium) for stabilization, along with trace amounts of Manganese, Silicon, Phosphorus, and Sulfur. This unique alloy offers excellent mechanical strength and corrosion resistance in high-temperature settings. Its mechanical properties include a tensile strength of about 515 MPa, a yield strength of 205 MPa, and an elongation of 35%. The addition of niobium helps prevent carbide precipitation during welding, which enhances its performance during thermal cycling and post-weld heat conditions.
