Introduction to Different Types of Carbon Steel

Carbon steel is a very common material in our daily life and in various industries. There are different types of carbon steel, such as grade 4.8, 6.8, and 8.8. These grades refer to the tensile strength of the steel. The higher the number, the greater the tensile strength.

When it comes to the surface treatment of carbon steel, we have self - color, plain, zinc - plated, and hot dip galvanized. Self - color carbon steel is in its natural state without any special surface treatment. Plain carbon steel also doesn't have any additional coatings or treatments for a special appearance.

Zinc - plated carbon steel has a layer of zinc on its surface. This is often done to prevent corrosion. Hot dip galvanized carbon steel is also a corrosion - resistant treatment. In this process, the carbon steel is dipped into a bath of molten zinc, which forms a thick and durable zinc coating on the surface.

Questions and Answers about Carbon Steel

Question 1: What are the differences between grade 4.8 and grade 8.8 carbon steel?Answer: Grade 8.8 carbon steel has a higher tensile strength than grade 4.8 carbon steel. Grade 4.8 is suitable for applications where less strength is required, while grade 8.8 can be used in more demanding situations where higher strength is needed.

Question 2: Which is more corrosion - resistant, zinc - plated or hot dip galvanized carbon steel?Answer: Generally, hot dip galvanized carbon steel is more corrosion - resistant. The hot dip galvanizing process creates a thicker zinc coating compared to zinc - plating, which provides better protection against corrosion.
