Filiz Steel, a trusted supplier located in Istanbul, Turkey, proudly offers top-notch **Carbon Steel ASTM A334 Grade 8 tubing**, specifically designed for **low-temperature service** in tough industrial settings. Crafted in line with the **ASTM A334 specification**, Grade 8 tubing is built to maintain its strength and toughness even in sub-zero temperatures, making it perfect for cryogenic and cold climate applications. Thanks to its **nickel-alloyed composition**, this grade boasts better impact resistance and ductility compared to regular carbon steel tubing.
This ASTM A334 Grade 8 tubing features **up to 0.50% nickel**, along with a maximum of **0.30% carbon** and **0.29–1.06% manganese**, which enhances its **low-temperature impact performance** and **weldability**. It offers a **minimum yield strength of 240 MPa** and a **minimum tensile strength of 415 MPa**, and has been **impact tested at -195°C (-320°F)**, making it suitable for extremely cold service conditions. Available in seamless form, it can be hot-finished or cold-drawn, with a variety of wall thicknesses and end preparations to meet customer needs.
