Filiz Steel, a reputable supplier based in Istanbul, Turkey, proudly presents its top-quality **Carbon Steel ASTM A334 Grade 9 tubing**. This tubing is specifically designed for **low-temperature service**, where outstanding impact resistance and structural integrity are essential. Crafted in accordance with the **ASTM A334 specification**, Grade 9 tubing is a **nickel-bearing low carbon steel** that excels in applications demanding remarkable toughness in **cryogenic and sub-zero environments**. It’s commonly utilized in **LNG processing**, **refrigeration systems**, and **petrochemical facilities**, where pipes face extreme cold conditions.
Typically, ASTM A334 Grade 9 tubing features **0.14–0.20% carbon**, **0.90–1.60% manganese**, and **0.40–1.06% nickel**, which contribute to its superior ductility and notch toughness compared to regular carbon steel. It boasts a **minimum yield strength of 240 MPa** and a **minimum tensile strength of 415 MPa**, and it must successfully undergo **impact testing at -100°F (-73°C)** to guarantee its performance in freezing environments. The material is available in **seamless form**, offered in both hot-finished and cold-drawn conditions, and can be tailored to specific sizes, wall thicknesses, and end types.
