What is the difference between 4130 and 4340

What is the difference between 4130 and 4340
2022-09-15 作者:Datong Hydraulic

4130 steel, as low alloy steel, contains high amounts of chromium and is often referred to as chromoly. 4130 steel has good machinability, ductility, weldability and strength characteristics. 4130 steel is used for many different industries including the automotive, aerospace ,hydraulic cylinder rod, cylidner barrel and machining industries.

4340 steel, as nickel-chromium-molybdenum alloy steel, is a very high strength steel. It is sought after for its toughness and for being used as a steel that will be highly stressed.

4340 steels are used in a variety of industries for different applications including the automotive, aerospace, and tooling industries.
