What is Q345 Low Temperature Cold Rolled Carbon Steel Plate？
Q345 is a kind of steel. It is a low alloy steel, widely used in bridges, vehicles, ships, buildings, pressure vessels, special equipment, etc., where "Q" means yield strength, and 345 means yield strength of this steel is 345MPa.
The yield value of Q345 will decrease with the increase of material thickness, and the domestic ones may be less than 345MPa, so the strength must be less than 345MPa in mechanical design, otherwise there will be problems.
Reference standard: GB/T1591-2018 Low Alloy High Strength Structural Steel

Advantages and Disadvantages of Carbon
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.
