Application
SAE8620H round steel is equivalent to what material? It is commonly used to manufacture gears in the engines and transmission systems of medium and small-sized cars and tractors; it can also replace 12CrNi3 steel for making carburized and nitrided parts with high core performance, such as the claw and wheel body of drill bits for oil drilling and open-pit mining in metallurgy. Due to the presence of molybdenum, 8620 not only has excellent comprehensive properties but also withstands certain temperatures, making it suitable for manufacturing turbine gear integral rotors, internal combustion engine connecting rods, and forging sections for engine valves.
