Introduction of materials:

Steel: A material of ingot, billet, or steel that is made by pressure processing into a variety of shapes, sizes, and properties.

Steel is an essential material for national construction and the realization of the four Modernizations. It is widely used and in various varieties. According to the different section shapes, steel is generally divided into four categories: profile, plate, pipe and metal products, and also divided into heavy rail, light rail, large section steel, medium section steel, small section steel, cold formed steel. High quality section steel, wire, medium thickness steel plate, thin steel plate, electrical silicon steel sheet, strip steel, seamless steel pipe steel, welded steel pipe, metal products and other varieties.

Characteristics:

Ferrous metal

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

Iron and steel

The pig iron used in steelmaking is put into the steelmaking furnace and smelted according to a certain process, that is, steel is obtained.

Non-ferrous metal

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

Nature:

1. Tensile strength

2. Elastic modulus

3. Plasticity

4, impact toughness, cold brittleness

5. Hardness

6, cold bending performance

7. Weldability

8. Heat treatment

9. Cold processing and aging
