What is Steel? What are the characteristics of steel?

Put the pig iron used in steelmaking into the steelmaking furnace and smelt it according to a certain process, that is, the steel is obtained. Steel products include steel ingots, continuous casting billets and direct casting into various steel castings. Generally speaking, steel generally refers to steel that is rolled into various types of steel. Steel belongs to ferrous metals, but steel is not exactly equal to ferrous metals.

Steel is an iron-carbon alloy with a carbon content in between. In order to ensure its toughness and plasticity, the carbon content generally does not exceed. In addition to iron and carbon, the main elements of steel are silicon, manganese, sulfur, phosphorus, etc. There are various ways to classify steel

<> advantages: 1. The steel has high strength, plasticity, heat resistance and toughness;

2. The steel material is uniform and the working reliability is high;

3. The steel structure is simple to make, the construction period is short, and it has good assembly;

4. The steel is weldable;

5. The steel has no leakage, which is convenient to make a closed structure;

6. Steel is closer to homogeneity and isotropy.

Disadvantages: 1. Poor corrosion resistance of steel;

2. The steel is heat-resistant but not fire-resistant;

3. Poor insulation effect of steel;

4. Steel is easy to distort.

Steel is a material of a certain shape, size and properties made by pressure processing of ingots, billets or steel nanomaterials. Most steel processing is carried out by pressure processing, which causes plastic deformation of the processed steel (billets, ingots, etc.). According to the different processing temperatures of steel, it can be divided into two types: cold working and hot working.

Next, I will introduce to you what steel is and what characteristics steel has.

1. What is steel?

Steel: It is a stool cover material of various shapes, sizes and properties required by pressure processing of ingots, billets or steel.

Steel is an indispensable important material for national construction and the realization of the four modernizations, its application is wide, variety, according to the different cross-sectional shapes, steel is generally divided into four categories: profiles, plates, pipes and metal products, and is divided into heavy rail, light rail, large section steel, medium section steel, small section steel, steel cold-formed section steel, high-quality section steel, wire rod, medium and thick steel plate, thin steel plate, electrical silicon steel sheet, strip steel, seamless steel pipe steel, welded steel pipe, metal products and other varieties.

Second, what are the characteristics of steel?

Ferrous. Ferrous metals mainly refer to iron, manganese, chromium and their alloys.

Steel. Put the pig iron used in steelmaking into the steelmaking furnace and smelt it according to a certain process, that is, the steel is obtained.

Nonferrous metal. Metals other than ferrous metals are called non-ferrous metals, such as copper, tin, lead, zinc, aluminum, brass, bronze, aluminum alloy and jujube bearing alloy.

Steel includes the following materials:

1. Rebar: The range of thread specifications is generally 6-50 mm, and the allowable deviation. The 9 mm thread is mainly used for road construction, and the 12 mm thread is mainly used for bridge construction;

2. Wire: The wire specification is generally mm mm, 10mm diameter, etc.;

3. Screws: As the name suggests, the advantages of snails are 9 to 12 snails of rebar, which can be intercepted at will according to demand;

4. Round bar: Round steel refers to the cross-section round solid bar steel, and its specification diameter is millimeters.
