Stainless steel screen surface chemical heat treatment process and purpose
Stainless steel screen works great, but it is worth mentioning stainless steel screen surface chemical heat treatment process.
Stainless steel screen surface chemical heat treatment is the use of solid state diffusion, the surface layers of alloy elements into the stainless steel screen of a heat treatment of advanced technology.
Its basic process is: first, the workpiece under infiltration of elements contained in the active medium heated to a certain temperature, is seeping into the elements by decomposition, absorption, diffusion into the stainless steel screen surface, which changes the composition, microstructure and properties of the surface.
So, we partition screen what is the purpose of the surface chemical heat treatment of stainless steel engineering?
First is to improve the fatigue of materials, such as carburizing, nitriding, chromizing infiltration layer due to the phase change of volume change, lead to produce very big residual compressive stress, surface fatigue strength is increased.
The second is to make stainless steel screen surface has a good resistance to adhesive, anti-seizure ability and reduce the friction coefficient, such as sulfurizing, etc.
Stainless steel screen and partition engineering can improve the corrosion resistance of the stainless steel screen surface, such as nitriding, aluminized etc.
The last partition screen stainless steel engineering to improve strength, hardness and wear resistance on the surface of the stainless steel screen.
Such as nitriding can make the partition of stainless steel screen surface hardness of 950 to 1200 hv,
Boronizing can make the partition of stainless steel screen surface hardness of 1400 to 200 hv, and workpiece surface has a very high wear resistance.
