Alloy steels with a total alloying element of less than 3.5% are called low alloy steels.Low alloy steel is relative to carbon steel. It is on the basis of carbon steel, in order to improve one or several properties of steel, and it is intended to add one or several alloy elements to steel.When the amount of alloy added exceeds the normal content of carbon steel in the normal production process, the steel is called alloy steel.When the total amount of alloy is less than 3.5%, it is called a low alloy steel.The alloy content between 3.5-10% is called medium alloy steel;More than 10% is called high alloy steel.
