Stainless Steel 304H Seamless Pipes are a type of austenitic stainless steel with a higher carbon content, which boosts strength at elevated temperatures. Typically, their composition consists of 18–20% Chromium, 8–11% Nickel, and 0.04–0.10% Carbon. This material is known for its excellent oxidation resistance, making it perfect for high-temperature applications. The mechanical properties include a minimum tensile strength of 515 MPa, yield strength of 205 MPa, and an elongation of 35%. These pipes also demonstrate good toughness and creep resistance, making SS 304H a great choice for environments that require structural integrity and thermal stability.
