Carbon Steel A334 GR 9 Tubing is a seamless, low-temperature carbon-molybdenum steel tubing crafted for pressure applications that demand toughness and strength in chilly environments. Shalan Steel, a reputable manufacturer and supplier located in Kuala Lumpur, Malaysia, offers high-quality A334 Grade 9 tubing that’s perfect for various cryogenic and industrial systems. These tubes are popular throughout Malaysia and Southeast Asia due to their outstanding low-temperature performance and durability.
ASTM A334 Grade 9 tubing features around 0.15% carbon, 0.50%–1.00% manganese, and 0.44%–0.65% molybdenum, all of which work together to boost strength and creep resistance. It boasts a minimum yield strength of 240 MPa and a tensile strength of at least 415 MPa. This tubing undergoes heat treatment through normalizing or quenching and tempering, ensuring reliable impact resistance even at temperatures as low as –50°F (–45°C), making it ideal for critical low-temperature operations.
