ASTM A252 Grade 3 Mild Steel Pipe Piles are structural steel pipes made from low carbon steel. Low carbon steel ensures excellent toughness, ductility, and weldability, making it suitable for heavy-duty piling and load-bearing construction applications.
Advantages
High Strength & Hardness: Grade 3 pipes have a minimum yield strength of 45,000 psi (310 MPa) and tensile strength of 66,000 psi (456 MPa), making them ideal for deep foundations and structural applications.
Good Toughness & Impact Resistance: Resistant to cracking under stress, ensuring reliability in dynamic and high-load environments.
Corrosion Resistance: Compatible with coatings such as FBE, 2LPE, 3LPE, galvanization, extending service life in marine, underground, or industrial conditions.
High Temperature Resistance: Maintains mechanical properties under elevated temperatures.
Compact Surface Finish: Smooth surfaces reduce friction during installation and improve structural stability.
Wide Application: Commonly used in water and gas transmission, urban pipe networks, municipal and urban construction, and steel structural buildings.
