Hot rolled steel is steel that has undergone the rolling process at a temperature above its recrystallization temperature (usually 1700° F or greater). Compared to unprocessed steel, the processed material exhibits greater formability and workability, making it easier to work with in subsequent processing
Carbon steel, also known as carbon steel, is an iron carbon alloy with an internal carbon content of nearly 2%. In addition to carbon, carbon steel contains many other elements, such as manganese, sulfur, or silicon. Generally speaking, the higher the amount of carbon contained in carbon steel, the greater its hardness, the higher the strength will be produced. Just note that the higher the carbon content, the lower the plasticity.
