Anti-collision pressure vessel steel for storing and transporting boron trifluoride and production method

The invention relates to anti-collision pressure vessel steel for storing and transporting boron trifluoride. The anti-collision pressure vessel steel comprises the following components in percentage by weight: 0.10-0.20% of C, 0.20-0.40% of Si, 1.25-1.70% of Mn, 0.025-0.045% of Al, less than or equal to 0.015% of P, less than or equal to 0.005% of S, 0.010-0.025% of V, 0.014-0.035% of Nb and the balance of Fe. The method comprises the following steps: after smelting and casting into a blank, heating the casting blank; rough rolling; finish rolling; cooling is performed; normalizing is conducted; and stress is eliminated. The static yield strength Rel ranges from 350 MPa to 430 MPa, the dynamic yield strength Re ranges from 470 MPa to 675 MPa, the tensile strength ranges from 510 MPa to 580 MPa, the yield ratio is smaller than or equal to 0.85, the static percentage elongation after fracture A ranges from 25% to 41%, the dynamic percentage elongation after fracture Ad ranges from 30% to 39.1%, and the product
