Chemical composition of a573 gr 65 structural carbon steel equivalent

Rolled sheet is a very common material in industrial construction. Rolled sheet at room temperature is cold-rolled sheet, and cold-rolled sheet is the rolling of hot-rolled coils below the recrystallization temperature. The hot-rolled sheet is rolled above the recrystallization temperature. So what is the difference between a573 gr 65 structural carbon steel, hot rolled sheet and cold rolled sheet?

Low alloy high strength steel is a kind of engineering structural steel developed by adding a small amount of Mn, Si and a small amount of Nb, V, Ti, Al and other alloy elements on the basis of carbon structural steel, a573 gr 65 structural carbon steel. The so-called low alloy means that the total amount of alloying elements in steel is less than 3%.
High strength is relative to carbon engineering structural steel. The development principle of low alloy high strength steel is to use as few alloy elements as possible to obtain as high comprehensive mechanical properties as possible, so as to meet the requirements of use and low cost.
