| description | The invention relates to acid-resistant steel as well as a preparation method and application thereof. The acid-resistant steel comprises the following chemical components: C, Si, Mn, P, S, Al, Nb, V, Cr, Sb, Ni, N and Fe. Wherein the content of the C is 0.010%-0.025% by mass, the content of the Mn is 0.2%-0.4% by mass, the content of the Cr is 1.3%-2.0% by mass, the content of the Sb is 0.03%-0.07% by mass, and the content of the Ni is 0.05%-0.10% by mass; and the following relational expression is satisfied: [Ni]/[Sb] > = 1.0. According to the acid-resistant steel, the yield strength reaches 1000 MPa or above, the tensile strength reaches 1100 MPa or above, the ductility reaches 5% or above, meanwhile, compared with Q345, the sulfuric acid corrosion resistance is improved by 50% or above, and cracking is avoided when 90-degree d = 1a small-angle bending is achieved.
本申请涉及一种耐酸钢及其制备方法与应用，所述耐酸钢的化学成分包括：C、Si、Mn、P、S、Al、Nb、V、Cr、Sb、Ni、N以及Fe；其中，以质量分数计，C的含量为0.010％～0.025％，Mn的含量为0.2％～0.4％，Cr的含量为1.3％～2.0％，Sb的含量为0.03％～0. |
