Application:

In construction projects, it can be used to fabricate large steel structures, such as plant frames and bridge structures.

In the machinery manufacturing industry, it is often used to make parts for heavy machinery.

For example, the boom of a crane, the bed of a machine tool. In the field of energy, it is suitable for the manufacture of wind power towers.

In shipbuilding, it can be used as the main material for the hull structure.

Physical and chemical properties:

Physical properties:

Density:

Approximately 7.85 grams per cubic centimeter.

Strength:

The yield strength is about 355 MPa, and the tensile strength is usually between 470 and 630 MPa.

Extensibility:

It has good ductility and toughness and can withstand a certain degree of deformation without cracking.

Hardness:

The hardness is moderate and can be adjusted by heat treatment.

Thermal Conductivity:

Good thermal conductivity, conducive to heat transfer.

Chemical properties:

Main components: Iron (Fe) is the main component, carbon (C) content is about 0.22%, and also contains manganese (Mn), silicon (Si), sulfur (S), phosphorus (P) and other elements. Oxidation resistance: The oxidation resistance is average at room temperature, and it is easy to oxidize in high temperature environment.

Corrosion resistance:

Corrosion resistance is relatively weak and susceptible to corrosive media.

For example, in mechanical manufacturing, its moderate hardness and good ductility make it easy to machine parts into complex shapes; while in some harsh chemical environments, protective measures need to be taken to prevent corrosion.
