A36 steel plate concept

A36 steel plate characteristics

High strength: The yield strength of A36 steel plate usually reaches or exceeds 250MPa, which has a high bearing capacity and is suitable for structural parts that need to bear large loads.

Good toughness: A36 steel plate can still maintain good toughness at low temperatures and is not easy to embrittlement, which is particularly important for structural parts used in cold areas.

Easy to process: A36 steel plate is easy to cut, drill, bend and weld and other processing operations, easy to make into various shapes and sizes of components.

Good corrosion resistance: Although the A36 steel plate itself is not a specialized corrosion resistant steel, after proper surface treatment (such as galvanized, spray painting, etc.), it can significantly improve its corrosion resistance and extend its service life.

Chemical composition of A36 steel plate

The chemical composition of A36 steel plate mainly includes carbon (C), silicon (Si), manganese (Mn), phosphorus (P), sulfur (S) and other elements, the specific content is as follows (different sources of data may be slightly different, but the approximate range is the same) :

Element content range

Carbon (C) ≤0.28%

Silicon (Si) ≤0.40%

Manganese (Mn) 0.6% ~ 0.9%

Phosphorus (P) ≤0.04%

Sulfur (S) ≤0.05%

Copper (Cu) When Cu is required, it should be more than 0.20% (but not all A36 steel plates include this requirement)

Delivery status of A36 steel plate

A36 steel plate is usually delivered in hot rolled state, but it can also be delivered in heat treatment such as normalizing and normalizing rolling according to user requirements. Different delivery conditions have different effects on the structure, properties and subsequent processing of steel plates.

A36 steel plate application range

A36 steel plate has a wide range of applications, including but not limited to the following aspects:

Industrial and civil construction: used in the manufacture of various welded and bolted metal structures, such as house frames, support structures, etc. Bridge construction: as an important part of bridge structure, such as bridge beam body, bridge deck pavement, etc.

Machinery manufacturing: Used to manufacture various mechanical equipment and parts, such as excavators, cranes, agricultural machinery and other structural parts.

Automobile manufacturing: It is also used in automobile manufacturing, such as body structure parts, chassis parts, etc.

Chemical equipment: used to manufacture pressure vessels and pipes in chemical equipment.

Architectural decoration: In the field of architectural decoration, A36 steel plates can be used to make stair handrails, railings and other structural parts.

Pressure vessels: Due to its high strength and good weldability, A36 steel plate is also suitable for manufacturing pressure vessels and other equipment that need to withstand high internal pressure.

Rail transit: In the field of rail transit, A36 steel plates can be used to manufacture structural parts and components of rail vehicles.
