Material: 3Cr13 stainless steel

 
Stainless steel grade: 3Cr13
Standard: GB/T 1220-2007
Features and scope of application:
The commonly used grades of martensitic stainless steels are 1Cr13, 3Cr13, etc., because of the high carbon content, they have high strength, hardness and wear resistance, but the corrosion resistance is slightly poor, which is used for high mechanical properties and corrosion resistance. General parts are required, such as springs, steam turbine blades, cutting tools, nozzles, valve seats, valves/hydraulic valves, etc. This type of steel is used after quenching and tempering.
