At Samia Pipes and Tubes, based in Tunis, Tunisia, we manufacture and supply premium Stainless Steel 316H Seamless Tubing engineered for high-temperature and pressure-intensive applications. The 316H grade features higher carbon content, which enhances strength and creep resistance at elevated temperatures while maintaining excellent corrosion resistance. Seamless construction ensures uniform wall thickness, superior mechanical integrity, and reliable performance under demanding service conditions. Produced with precision and strict quality control, our tubing meets international standards. Trusted by industries across Tunisia and beyond, Samia Pipes and Tubes delivers seamless tubing solutions that support safe, efficient, and long-lasting industrial operations.
Stainless Steel 316H Seamless Tubing is an austenitic stainless steel composed mainly of iron, chromium (16–18%), nickel (10–14%), and molybdenum (2–3%), with higher carbon content for improved high-temperature strength. This composition provides excellent resistance to corrosion, oxidation, and creep at elevated temperatures. Typical tensile strength ranges from 515–690 MPa, with yield strength of approximately 205–310 MPa. Seamless construction eliminates weld joints, ensuring consistent mechanical properties, high pressure resistance, and dependable performance in thermal and mechanical stress environments.
