Looking for a reliable source of **Carbon Steel ASTM A423 Grade 1 tubing**? Look no further than Filiz Steel, a reputable supplier based in Istanbul, Turkey. Our tubing is expertly crafted for **boiler and heat exchanger service**, making it perfect for environments that might encounter corrosive flue gases or moderate temperatures. Adhering to the **ASTM A423 specification**, our Grade 1 tubing is a seamless, cold-drawn carbon steel product that excels in **corrosion-resistant heat recovery systems**, **waste heat boilers**, and **economizers**. Its impressive resistance to high-temperature oxidation and sulfur-rich combustion gases makes it a top choice for energy and power plant applications.
When it comes to composition, ASTM A423 Gr. 1 tubing typically features **0.18% maximum carbon**, along with **0.27–0.63% manganese**, and carefully controlled levels of phosphorus and sulfur to enhance corrosion resistance. This tubing boasts a **minimum yield strength of 205 MPa** and a **minimum tensile strength of 380 MPa**, ensuring it has the strength required for pressure-containing systems while still being ductile enough for forming and bending. Produced in a **cold-drawn seamless form**, it guarantees tight dimensional tolerances and smooth finishes, which are crucial for optimal performance during thermal cycling.
