Filiz Steel, a reputable supplier located in Istanbul, Turkey, proudly provides high-quality **Carbon Steel ASTM A334 Grade 6 tubing**, specifically engineered for **low-temperature service** where strength, toughness, and reliability are paramount. This tubing is crafted in line with **ASTM A334 specifications** and stands out as the most commonly used material in its category, delivering exceptional performance even in sub-zero conditions. It finds its place in various industries, including **oil and gas, petrochemicals, LNG, power generation, and cryogenic services**, where reliable operation in extreme cold is a must.
Typically, ASTM A334 Grade 6 tubing features **0.30% maximum carbon**, **0.29–1.06% manganese**, along with minimal phosphorus and sulfur content, resulting in a **minimum yield strength of 240 MPa** and a **minimum tensile strength of 415 MPa**. To guarantee toughness and resistance to brittle fracture, it undergoes **Charpy V-Notch impact testing at -45°C (-50°F)**. The tubing is available in a **seamless form**, offered in either hot-finished or cold-drawn conditions, and can be tailored in terms of length, wall thickness, and end finishes.
