Carbon Steel A334 GR 3 Tubing is a seamless pipe designed for low-temperature service, perfect for pressure systems that demand high toughness and reliability in chilly conditions. Shalan Steel, a well-respected manufacturer and supplier based in Kuala Lumpur, Malaysia, provides top-notch A334 Grade 3 tubing that adheres to ASTM standards. These tubes are widely trusted across Malaysia and Southeast Asia, especially in critical applications within the oil, gas, and power industries.
The ASTM A334 Grade 3 tubing features a composition of 0.19–0.25% carbon and 0.40–0.60% manganese, ensuring a minimum tensile strength of 415 MPa and a yield strength of 240 MPa. To boost low-temperature impact resistance and guarantee consistent performance even at temperatures as low as –45°C, these tubes are either normalized or heat-treated. They also offer good machinability and weldability, making them ideal for fabrication and installation in challenging environments.
