Liam Pipes & Tubes offers specialized Stainless Steel 316H instrumentation tubing from Houston, USA, designed for ultra-high-temperature and heavy-duty applications. With higher carbon content, 316H provides greater strength and creep resistance at elevated temperatures. Manufactured to strict tolerances and quality standards, our tubing supports critical instrumentation in harsh environments. Serving power plants, refineries, petrochemical industries, and thermal systems, our 316H tubing meets ASTM and ASME requirements. With traceability and certifications, Liam delivers premium tubing for temperature-sensitive pressure and flow measurement systems, ensuring consistent performance and integrity under extreme thermal and pressure conditions.
SS 316H includes about 16–18% Cr, 10–14% Ni, around 2–3% Mo, and higher carbon content of about 0.04–0.10% to improve high-temperature strength. Mechanical properties typically include a tensile strength of around 515 MPa, yield strength of about 205 MPa, and elongation of about 30%. The increased carbon enhances creep and stress-rupture resistance at high temperatures. 316H shows strong oxidation resistance, maintains dimensional stability under heat stress, and is easy to machine. It’s well suited for welded instrumentation tubing operating in harsh, high-temperature applications, maintaining mechanical performance where standard grades may fail.
