The difference between the two is defined somewhat arbitrarily. However, most agree that any steel that is alloyed with more than eight percent of its weight being other elements beside iron and carbon, is high alloy steel.

GB 20CrMnTi GB/T 3077 - BBN STEEL STORESGB 20CrMnTi GB/T 3077 In addition to carbon, steel also contains a small amount of manganese (Mn), silicon (Si), sulfur (S), phosphorus (P), oxygen (O), nitrogen (N) and hydrogen (H). These elements are not intentionally added to improve the quality of steel, but are brought in by ore and smelting process, so they are called impurity elements.National Standard of PRC Alloy Structure Steels GB/T The standard will replace GB/T 3077-1988 from the date of the implementation of this standard.
