What is SM400B,SM400A and SM400C steel?

SM400B, SM400A, and SM400C are three different types of carbon steel plates that belong to the JIS G3106 standard. These steels are known for their high-strength properties and excellent performance in hot rolled coils.

SM400B steel is a material that contains more than 0.20 percent carbon, which makes it ideal for applications requiring high strength and resistance to corrosion. It is commonly used in construction projects such as bridges, buildings, and towers.

On the other hand, SM400A steel has a lower carbon content compared to SM400B but still offers impressive mechanical properties suitable for various structural applications like machinery parts, vehicles frames or metal structures.

We have SM400C steel which contains less than 0.2% carbon making it easier to weld and form into different shapes without sacrificing its strength properties. It also exhibits good toughness even at low temperatures.

Each type of steel has unique chemical compositions and standards that make them suitable for various industrial purposes where reliable performance under extreme conditions is required.

What’s difference SM400A SM400B and SM400C steel plate?

SM400A, SM400B, and SM400C are all grades of high-strength structural steel that are commonly used in the construction industry. While they have similar chemical compositions, there are some differences between them that make each grade suitable for different applications.

The main difference between SM400A, SM400B, and SM400C is their carbon content. The carbon content in these grades ranges from 0.18% to 0.23%, with SM400B having a slightly higher percentage than both SM400A and SM400C.

Another factor that sets these grades apart is their strength levels. Among the three grades of steel plates, SM400B has the highest yield strength at 245 MPa while both SM300A and C have a lower yield strength of 235 MPa.

Lastly,the welding properties also vary among the three grades with slight differences which need to be considered when selecting one for specific applications

Overall ,while there are subtle differences among these steel plate materials,it’s always important to choose the right material based on your needs such as application requirements or budget constraints
