Nitriding Treatment Skd11 Mold Steel Wide Range Of Uses - China

SKD11 mold steel nitriding treatment

After the nitriding treatment of the mold or workpiece, a layer of hardened structure with high hardness and certain corrosion resistance is formed on the surface.

The surface hardness of the workpiece nitrided at 525°C is about 1250HV.

The effect of nitriding time on the nitrided layer is as shown in the table below.

Nitriding time (hours) 20 30 60 Nitriding layer depth mm 0.25 0.30 0.35 Soft nitriding treatment at 570℃

The surface hardness of the workpiece is approximately 950HV.

Usually, after 2 hours of soft nitriding treatment, the depth of the hardened layer can reach 10-20um.

Grinding the mold base or working in a low-temperature tempering state is prone to grinding cracking.

In order to prevent the occurrence of cracks, small grinding feeds should be used for multiple grinding times, and good water cooling conditions should be added.

When molds with complex shapes or large sizes are processed by wire cutting, cracking will usually occur when the molds are finally processed by wire cutting.

In order to prevent cracking, it is recommended to use gas quenching and high-temperature tempering to reduce heat treatment stress, or to perform cavity preprocessing on the mold base.
