Round steel is divided into three types: hot rolled, forged and cold drawn.
Hot rolled round steel is 5.5-250 mm in size.
Among them: 5.5-25 mm small round steel mostly in straight bundles supply, commonly used for reinforcing bars, bolts and various mechanical parts;
Round steel larger than 25 mm, mainly used in the manufacture of machine parts, seamless steel tube billet, etc.

What are the 3 types of carbon steel?
The carbon present in steel is typically reduced so that it fits into three main categories of carbon steel: low (or mild), medium and high carbon steel.

What is low carbon steel grade?
Low-carbon steel consists of less than 0.30% carbon. Medium-carbon steel consists of 0.30% to 0.60% carbon. And high-carbon steel contains more than 0.60% carbon. As the carbon content of steel increases, it becomes stronger and harder.
