SSAW Steel Pipe ASTM A252 GR.2
The chemical composition of ASTM A252 GR.2 spiral steel pipe complies with international standards. The main components are iron, carbon, silicon, manganese and other elements. Among them, the carbon content is low, only about 0.2%, which makes the steel pipe have good weldability and toughness.
ASTM A252 spiral steel pipe has excellent mechanical properties, high strength and toughness. Its tensile strength is generally between 400-550MPa, and it also has good low-temperature toughness and can maintain good performance at lower temperatures.
ASTM A252 GR.2 carbon steel pipe is manufactured using hot-rolled or cold-drawn seamless pipe technology, with smooth surface, high dimensional accuracy, and easy for deep processing and welding. This manufacturing process ensures the quality and reliability of steel pipes.
