Abstract

The invention discloses anti-corrosion rolled steel and a manufacturing method thereof, and belongs to the technical field of rolled steel. The anti-corrosion rolled steel is formed by mixing the following main components including, by weight, 5-10% of silicon, 3-6% of tungsten, 3-6% of manganese, 2-5% of phosphorus, 2-5% of sulfur, 0.2-3% of carbon, 0.1-3% of niobium, 0.1-2% of titanium, 3-10% of molybdenum, 2-6% of chromium, 1-4% of boron, 3-8% of a binder, 2-7% of an anti-corrosion agent, 0.1-3% of a fire retardant, 1-5% of a forming agent, 0.2-6% of a passivator, 1-5% of an antioxidant and the balance iron. The manufacturing method of the rolled steel is simple and effective, and the manufactured rolled steel has good hardness, corrosion resistance, yield strength and tensile strength.

Description

technical field [0001] The invention relates to the technical field of steel production, in particular to a corrosion-resistant steel and a manufacturing method thereof. Background technique [0002] Steel is an essential and important material for national construction and the realization of the four modernizations. It is widely used and has a variety of varieties. According to the different cross-sectional shapes, steel is generally divided into four categories: profiles, plates, pipes and metal products. [0003] Generally, in order to improve the strength of steel, alloying elements are usually added to alloy the steel, followed by heat treatment such as controlled rolling, controlled cooling, quenching and tempering, or addition of precipitation hardening elements. Alloy structural steel is widely used in the manufacture of various transmission parts and fasteners for automobiles, tractors, ships, steam turbines, and heavy machine tools. For alloy steel, high hardness,...
