Yousef Steel, a trusted steel manufacturer and supplier located in Riyadh, Saudi Arabia, provides top-notch **Carbon Steel A53 Grade C pipes** that are perfect for pressure and mechanical applications in both industrial and commercial settings. ASTM A53 Gr C is a carbon steel pipe grade, either seamless or welded, recognized for its superior strength compared to Grades A and B. This makes it an excellent choice for structural, steam, water, gas, and air transportation services. Yousef Steel adheres strictly to ASTM standards, ensuring that their piping solutions are both durable and cost-effective.
ASTM A53 Gr C pipes feature a higher carbon content (up to 0.35%) and boast improved mechanical properties, with a minimum yield strength of 276 MPa and a minimum tensile strength of 485 MPa. These pipes are known for their good formability, weldability, and toughness, even in moderate to high-pressure environments. They come in both seamless (Type S) and welded (Type E) options, produced with either hot-dip galvanizing or black surface finishing, depending on what the application requires.
