Based in Houston, Texas, Liam Pipes and Tubes is a reputable producer and supplier of stainless steel 309H tubing. With a focus on high-temperature tubing solutions, we provide premium-grade 309H tubing that is resistant to corrosion and extremely high temperatures. Stainless Steel 309H is an improved form of SS 309 with a higher carbon content, which makes it perfect for uses where exceptional strength at high temperatures is required. Liam Pipes and Tubes offers seamless and welded versions in custom sizes to meet a range of industrial needs. We guarantee timely delivery, reliable quality, and top-notch customer service to customers in a variety of industries.
With a carbon content of 0.04–0.10%, 12–15% nickel, and roughly 22–24% chromium, stainless steel 309H tubing is a high-carbon version of SS 309 that improves its strength at high temperatures. It also contains trace amounts of sulphur, silicon, and manganese. In terms of mechanical properties, 309H provides a yield strength of 205 MPa (30 ksi), a tensile strength of approximately 515 MPa (75 ksi), and outstanding resistance to creep and thermal fatigue. It is a dependable option for heat-intensive applications because of its higher carbon content, which enhances structural integrity in prolonged high-heat environments.
