ASTM A36 Steel Plate Description

 

As a kind of carbon structural steel plate, the ASTM A36 steel plate contains a small amount of alloying elements such as silicon, manganese, phosphorus, etc. These alloying elements make the steel plate have excellent mechanical properties and weldability. Its chemical composition strictly follows the provisions of the American Society for Testing Materials standards.

 

Mechanical Properties of ASTM A36 steel plates

 

Yield Strength

 

The yield strength of ASTM A36 steel plates is usually greater than 250MPa, which means the plastic deformation begins when the steel plate is subjected to external forces is not less than 250MPa.

 

Tensile Strength

 

The maximum stress intensity that ASTM A36 steel plates can withstand before tensile fracture varies from 400MPa to 550MPa.

 

Elongation

 

The elongation of the ASTM A36 steel plate is greater than 20%, which means that the steel plate is subjected to plastic deformation and is not easy to break.

 

Delivery Condition of ASTM A36 Steel Plate

Hot Rolled

ASTM A36 steel sheet is delivered directly after high-temperature rolling, and the surface has a certain oxidation scale, which needs to be further cleaned and treated.

Normalized

Normalizing means that the A36 steel plate is heated to a temperature, and held for a period of time after cooling and then delivery. This treatment method improves the mechanical properties of the steel plate.

Normalized and Rolled

A36 steel plate is delivered after normalizing and rolling. This type of steel plate has better dimensional accuracy and surface quality.

ASTM A36 Steel Plate Manufacturing Process

 

ASTM A36 steel plate manufacturing process mainly includes steelmaking, rolling, heat treatment, and other steps, detailed in the following:

Smelting

 

In the smelting process of steel plate, an electric arc furnace or converter smelting process is generally used to ensure the purity and accuracy of the composition of molten steel.

Uses Of ASTM A36 Carbon Steel Plates

 ASTM A36 steel plate has a wide range of applications, and common uses can be classified as follows:

 

1. Infrastructure and high-rise buildings

Steel structural parts, beams, columns, etc. of various infrastructures are usually manufactured from ASTM A36 steel plates. Especially, modern high-rise buildings' steel frames consist of ASTM A36 steel, ASTM A572 steel, etc.

2. Machinery manufacturing

Due to excellent machinability and weldability, ASTM A36 steel is often used in the manufacture of mechanical parts such as bearings and hydraulic supports.

3. Manufacture of vehicles and ships

Dump trucks, forklifts, ships and other tools play an important role in various fields. ASTM 36 steel plates also play a significant role in the manufacture of high-strength components such as body, hull and cabin.

4. Explosion field

In mining and quarrying operations, ASTM-A36 steel plates are also used in the manufacture of mining equipment such as conveyor brackets, mine steel structures, hydraulic steel structures, steel frame platforms, etc.
