| The
chemical composition of A252 steel pipe mainly consists of iron, carbon,
silicon, manganese and other elements, of which the carbon content is low,
only about 0.2%. A252 steel pipe piles has excellent mechanical properties,
high strength and toughness, tensile strength is generally between
400-550MPa, and has good low-temperature toughness. A252 seamless welded pipe
piles play an important role in petroleum, chemical industry, machinery,
construction and other fields. |
