When it comes to the Composition and Mechanical Properties of Carbon Steel Pipe Caps, Phanuphong Steel typically uses grades like ASTM A234 WPB or ASTM A105. The composition features carbon (0.20–0.30%), manganese (0.60–1.65%), phosphorus (≤0.035%), and sulfur (≤0.040%). These pipe caps boast impressive mechanical properties, including a tensile strength of 415–485 MPa, a yield strength of at least 240 MPa, and a minimum elongation of 20%. Their high strength and toughness make them perfect for high-pressure applications. They undergo heat treatment and normalization to boost durability, corrosion resistance, and weldability, making them suitable for a variety of industrial piping systems.
