Carbon Steel A334 GR 11 Tubing is a seamless, low-temperature steel tubing crafted for pressure applications in cryogenic and sub-zero settings. Shalan Steel, a trusted manufacturer and supplier located in Kuala Lumpur, Malaysia, offers top-notch A334 Grade 11 tubing that adheres to ASTM standards. This tubing is widely utilized throughout Malaysia and Southeast Asia in industries that demand strength, ductility, and impact resistance even in frigid conditions.
The ASTM A334 Grade 11 tubing is enhanced with small amounts of chromium (0.44–0.65%) and molybdenum (0.44–0.65%), which boost its strength, oxidation resistance, and creep resistance. It boasts a minimum tensile strength of 415 MPa and a yield strength of 240 MPa. To ensure it maintains its impact toughness at temperatures as low as –50°F (–45°C), the tubing undergoes normalization or quenching and tempering, guaranteeing reliable mechanical performance even in extreme environments.
