A36 and A572 are two common grades of steel that are used in various industries. Both of them are ASTM standards, which means they are certified by the American Society for Testing and Materials. In this article, we will take a closer look at A36 and A572 and understand their similarities and differences.
A36 is a low carbon steel that is used in various applications such as construction, shipbuilding, and manufacturing. It has a minimum yield strength of 36,000 psi and a minimum tensile strength of 58,000 psi. A36 is known for its excellent weldability and formability, making it a popular choice among fabricators and manufacturers.
On the other hand, A572 is a high-strength, low-alloy steel that is used in structural applications such as bridges, buildings, and heavy equipment. It has a minimum yield strength of 50,000 psi and a minimum tensile strength of 65,000 psi. A572 is known for its superior strength and durability, making it a preferred choice for demanding applications.
One of the main differences between A36 and A572 is their chemical composition. A36 is made of carbon, manganese, phosphorus, sulfur, and silicon, while A572 is made of carbon, manganese, phosphorus, sulfur, silicon, columbium, and vanadium. Due to these additional elements, A572 has superior strength and toughness compared to A36.
Another difference between A36 and A572 is their applications. A36 is mainly used in general construction, whereas A572 is used in structural applications where high strength and toughness are required. A36 is also used in low-stress applications such as tanks and containers, while A572 is used in high-stress applications such as bridges and buildings.
When it comes to price, A36 is generally cheaper than A572 due to its lower strength and simpler chemical composition. However, the price difference may vary depending on the supplier and the specific requirements of the project.
In conclusion, both A36 and A572 have their own strengths and weaknesses. A36 is a versatile and affordable steel that is commonly used in various industries, while A572 is a high-strength steel that is preferred in structural applications where superior strength and toughness are required. Understanding the similarities and differences between these two types of steel can help in making the right choice for specific applications.
