Video details

The raw material used in inserts produced by Qinsen is 20CrNiMo. 20CrNiMo steel is originally the steel number 8620 in the American AISI and SAE standards. The hardenability is similar to that of 20CrNi steel. Although the Ni content in the steel is half of that of the 20CrNi steel, the addition of a small amount of Mo element makes the upper part of the austenite isothermal transformation curve move to the right; and due to the appropriate increase in the Mn content, the hardenability of this steel is still very good, and the strength Also higher than 20CrNi steel. It is often used in the manufacture of gears in the engine and transmission system of small and medium-sized automobiles and tractors; it can also replace 12CrNi3 steel to manufacture carburized parts and cyanide parts that require high core performance, such as roller cone bits for oil drilling and metallurgical open-pit mines claws and cones.
