ST42 Carbon steel pipe

The minimum tensile strength of an ST42 carbon steel pipe must be no less than 42 kgf/mm², equivalent to 420 MPa. This type of steel pipe adheres to the German standard for seamless steel pipes and finds extensive application across various fields. These seamless pipes are typically manufactured from common carbon structural steel, low-alloy structural steel, or alloy structural steel, boasting significant production volumes. Their primary use is for fluid transport or as structural components.In summary, the ST42 carbon steel pipe not only meets important standards in terms of mechanical properties like tensile strength but also serves a critical function in industrial applications due to its material composition and manufacturing process, making it suitable for transporting fluids or serving in structural roles.
