Q235B ordinary carbon structural steel is also called A3 plate.
Ordinary carbon structural steel-plate is a kind of steel material.
Q represents the yield limit of this material, and the following 235 refers to the yield value of this material, which is about 235MPa.
Due to its low carbon content, good comprehensive performance, and good combination of strength, plasticity and welding properties, it is the most widely used.

Advantages
1. The raw material of carbon steel is easy to find, so it is usually low in production cost.
2. It has a robust construction, high ductility, easy fabricating, good abrasion resistance, and great versatility.
3. It is in a wide selection of thicknesses, sizes, grades, and types to choose from.
4. Being a cost-effective alternative to GI, GL, and SS steel.
Disadvantages
1. High carbon sometimes are too difficult to work with.
2. Relatively speaking, it is less attractive, and more susceptible to rust and corrosion.
3. When the temperature exceeds 200 degrees, the wear resistance of the carbon plate will deteriorate.
4. Its hardenability is not good, prone to deformation or cracking when doing so.
