At Samia Pipes and Tubes, based in Tunis, Tunisia, we manufacture and supply premium Stainless Steel 304H Seamless Tubing designed for high-temperature and pressure-demanding applications. The 304H grade features higher carbon content, which improves strength and creep resistance at elevated temperatures while retaining excellent corrosion resistance. Seamless construction ensures uniform wall thickness, superior mechanical integrity, and reliable performance under demanding service conditions. Manufactured with precision and strict quality control, our tubing meets international standards. Industries across Tunisia and beyond rely on Samia Pipes and Tubes for seamless tubing solutions that deliver durability, safety, and long-term reliability.
Stainless Steel 304H Seamless Tubing is an austenitic stainless steel composed primarily of iron, chromium (18–20%), and nickel (8–11%), with higher carbon content to enhance high-temperature strength. This composition offers good oxidation resistance, toughness, and creep resistance at elevated temperatures. Typical tensile strength ranges from 515–620 MPa, with yield strength of approximately 205–310 MPa. Seamless construction eliminates weld joints, ensuring consistent mechanical properties, high pressure tolerance, and dependable performance under thermal and mechanical stress conditions.
