Characteristics and application: This steel series is imported from American AISI/SAE standard steel grade 8720. Its hardenability is similar to that of 20CrNi steel, and its strength is higher than that of 20CrNi steel. Used to manufacture gears for engines and transmission systems of small and medium-sized cars and tractors; It can also replace 12CrNi3 to manufacture carburized steel and carbonitriding parts with higher requirements for central performance, such as the jaw and cone body of cone bits for oil drilling and metallurgical mining.
