Parameters

Product name: 5KW rotor shaft

Material: 20CrMoTi-H

Steel management requirements:

1. The spline ends are forged and normalized, and the hardness is HB170-210;

2. 23-28HRC after rough machining of the rough material;

3. After quenching and tempering, the metallographic organization of the workpiece is rated according to the third group of FB/T 13320-2007

Image inspection, the level is 1-3;

4. After surface carbonitriding is quenched and tempered at low temperature, the surface depth is 58-62HRC; the depth of the quenched layer is 550HV=0.7-1mm, the metallographic structure is inspected according to the JB/T9204-2008 rating chart, and the level is 3-7 class;

5. The core hardness is HRC32-45, in addition to hydrogen and stress, the hydrogen content is less than 1.1e-6.
