David Pipes and Tubes, located in Canberra, Australia, is a well-respected manufacturer and supplier of top-quality stainless steel 309H tubing. These tubes are engineered to excel in high-temperature and corrosive settings, offering remarkable resistance to oxidation and scaling. With their impressive strength, durability, and excellent weldability, stainless steel 309H tubing is perfect for tough industrial applications. David Pipes and Tubes is committed to ensuring that each tube adheres to rigorous international standards, providing consistency, precision, and long-lasting reliability for use in thermal, chemical, and process industries.
The composition of stainless steel 309H tubing primarily includes chromium (22–24%) and nickel (12–15%), along with a higher carbon content compared to 309 or 309S, which boosts its strength and creep resistance at elevated temperatures. This alloy showcases a tensile strength ranging from 515 to 700 MPa, a yield strength of 205 MPa, an elongation of 40%, and a hardness of about 90 HRB. It maintains outstanding oxidation resistance up to 1100°C and ensures excellent structural stability even when exposed to high heat for extended periods.
