Stainless Steel 304H Instrumentation Tubing is a high-carbon variant of SS 304, specifically crafted for high-temperature applications. Its typical composition includes Chromium (18–20%), Nickel (8–11%), Carbon (0.04–0.10%), Manganese, Silicon, and trace elements. The higher carbon content enhances its strength at elevated temperatures and improves creep resistance. It offers a minimum tensile strength of 515 MPa, a yield strength of at least 205 MPa, and an elongation of 40%. This tubing showcases remarkable corrosion resistance, particularly in oxidizing environments, while maintaining toughness and ductility at high temperatures, making it ideal for demanding instrumentation and control applications.
