What is ASTM A36 Plates Properties, Uses And Composition

Steel plates are widely used in construction due to their high strength and durability. One common type of steel plate is the ASTM A36, which is a carbon steel plate that is used across a variety of different applications. This blog post will discuss the properties, uses, and composition of ASTM A36 plates and why they are valuable for construction.

What is ASTM A36 Plates?

ASTM A36 Plates are structural, carbon-steel plates that are used for a variety of applications. These plates have moderate strength and are easy to fabricate. They can be riveted, bolted, or welded in constructing bridges and buildings for general structural purposes. Additionally, they also possess good formability and wear resistance properties, which make them ideal for a variety of types of projects. The steel is strong yet malleable, making it extremely versatile in various industries such as automotive, manufacturing plants, etc. Furthermore, ASTM A36 Plates come in sizes ranging from 3/16” thick to 12” thick.


ASTM A36 plates are made of 0.25% carbon, and iron, sulfur, phosphorus, and silicon can be found in smaller amounts. This composition gives the steel its unique strength and durability properties, making it ideal for construction.


ASTM A36 plates yield 250 MPa (megapascals) and a tensile strength of 400-550 MPa. This means that the plates can withstand significant pressure and force, making them ideal for use in heavy-duty machinery and construction equipment.


One of the main uses of ASTM A36 plates is in the construction industry, where they are commonly used for building structures such as bridges, buildings, and roads. They can also be used in manufacturing trucks, trailers, and agricultural equipment due to their high strength and durability. Additionally, the plates are used to produce pipelines and oil rigs because of their excellent performance in high-pressure environments.

Welding and Machining

ASTM A36 plates are easy to weld, making them ideal for construction applications that require welding. They can also be machined easily, making them ideal for use in various manufacturing processes.

Maintenance and Cost

One of the biggest advantages of ASTM A36 plates is their low maintenance requirements. This makes them cost-effective, as they require little upkeep over time. Furthermore, their widespread use in the construction industry makes them readily available and affordable.


In conclusion, ASTM A36 plates are an excellent choice for construction and manufacturing applications due to their unique properties, uses, and composition. They are widely used in the construction industry for building structures and in manufacturing heavy machinery, pipelines, and oil rigs. Furthermore, their low maintenance requirements make them cost-effective and easy to use, making them a popular choice across various industries.
