The invention discloses anti-
corrosion steel for a bridge tubular
pile. The anti-
corrosion steel comprises the following components in percentage by weight: 0.07-0.13% of C, 0.30-0.65% of Si, 0.80-1.30% of Mn, 0.025-0.045% of P, less than or equal to 0.002% of S, not greater than 0.006% of Al, 0.035-0.050% of V, 0.008-0.025% of Ti, 0.005-0.02% of Re, 0.006-0.012% of Zr and 15-30ppm of dissolved [O]. A production method of the anti-
corrosion steel comprises the following steps: performing converter
smelting and
continuous casting to obtain a blank; performing stack cooling on the
casting blank; heating the
casting blank; performing sectional rolling; performing conventional
laminar cooling; coiling; and performing
air cooling to
room temperature. According to the anti-corrosion steel disclosed by the invention, the yield strength is greater than or equal to 390MPa, the tensile strength is greater than or equal to 510MPa, the elongation A is greater than or equal to 21%, the
impact energy Akv at 0 DEG C is greater than or equal to 47J, the corrosion resistance is equivalent to that of the American Corten B steel, the thickness specification of a steel plate is 20-25mm, the production cost is low, and the large-scale production requirement is met; moreover, a straight
welding pipe is replaced to manufacture the bridge steel tubular
pile, the production efficiency can be remarkably improved, and the production cost of the steel tubular
pile is lowered.
