Abstract

The invention discloses a corrosion-resistant steel. The corrosion-resistant steel comprises the following raw material components of, by weight, 0.035%-0.045% of a carbon element, 11%-13% of a chromium element, 2.3%-2.5% of a manganese element, 1.5%-2.5% of a nickel element, 0.1%-0.2% of a silicon element, 0.2%-0.4% of a molybdenum element, 0.4%-0.5% of a copper element, 0.02%-0.04% of a niobiumelement, 0.01%-0.05% of a vanadium element and the balance an iron element. Meanwhile, the invention discloses a preparation method of the corrosion-resistant steel. According to the corrosion-resistant steel and the preparation method, the corrosion resistance of the steel is effectively improved.

Description

technical field [0001] The invention relates to the field of steel products, in particular to a corrosion-resistant steel product and a preparation method thereof. Background technique [0002] Steel is a general term for iron-carbon alloys with a carbon content between 0.02% and 2.11% by mass. In industrial applications, steel will encounter some special environments, such as salt, chloride ion, carbon dioxide, hydrogen sulfide, sulfide, acid, alkali, water containing corrosive compounds and other corrosive media. Over time, it has a great impact on the appearance and performance of steel. In addition, as time goes on, the corrosion phenomenon will become more serious, resulting in the failure of the steel to be used normally. [0003] The corrosion resistance of steel in the prior art is not strong enough, and it cannot withstand the strong corrosion of various corrosive media such as salt, chloride ion, carbon dioxide, hydrogen sulfide, sulfide, acid, alkali, water cont...
