These tubes are produced using cutting-edge technology and rigorous quality control measures to guarantee precise dimensions and top-notch performance. Kyaw Stainless’s Stainless Steel 304H Tubing is perfect for high-temperature and high-pressure applications. Thanks to its higher carbon content, this grade boasts enhanced tensile and creep strength, making it a go-to choice for industries like petrochemical, power generation, heat exchangers, and boilers.
The composition of Stainless Steel 304H Tubing includes about 18–20% chromium, 8–11% nickel, and a higher carbon content that ranges from 0.04–0.10%. It also contains trace amounts of manganese, silicon, phosphorus, and sulfur, with iron making up the rest. The elevated carbon level contributes to its superior mechanical strength and oxidation resistance at high temperatures. These tubes have a tensile strength of around 515 MPa and a yield strength of approximately 205 MPa, along with excellent toughness, weldability, and resistance to scaling up to 870°C.
