At Samia Pipes and Tubes, based in Tunis, Tunisia, we manufacture and supply premium Stainless Steel 310H Seamless Tubing engineered for extreme heat and high-temperature industrial applications. The 310H grade is known for its high chromium and nickel content combined with higher carbon levels, providing exceptional strength, creep resistance, and oxidation resistance at elevated temperatures. Seamless construction ensures uniform structure, excellent pressure resistance, and long-term reliability under thermal stress. Manufactured with precision and strict quality control, our tubing meets international standards. Trusted by industries across Tunisia and beyond, Samia Pipes and Tubesdelivers seamless tubing solutions that ensure safe, efficient, and durable performance in the most demanding environments.
Stainless Steel 310H Seamless Tubing is a high-alloy austenitic stainless steel composed mainly of iron, chromium (24–26%), and nickel (19–22%), with higher carbon content to enhance high-temperature strength and creep resistance. This composition provides excellent resistance to oxidation, scaling, and corrosion at elevated temperatures. Typical tensile strength ranges from 515–700 MPa, with yield strength of approximately 205–310 MPa. Seamless construction eliminates weld seams, ensuring uniform mechanical properties, superior pressure-handling capability, and dependable performance under extreme thermal and mechanical conditions.
