Speaking of powder metallurgy mold processing materials, in terms of its wear resistance in terms of words, in fact, is the most basic mold is one of the most important performance. Hardness will affect the main factors of wear resistance. In general, the higher the hardness of the powder metallurgy mold parts, it will show the less wear and tear, wear resistance will be better. In addition, the wear resistance and the mold material which the type of carbide and its number and size have a great relationship.
Powder metallurgy mold processing materials selection, that is, to pay attention to its strength and toughness. Mold in the long-term role of cyclic stress, need to bear multiple shocks, there will be a relatively large impact load, this way, it will be easier to cause it to break the situation. In order to effectively prevent the mold parts in the work of a sudden break when the situation, the mold should also have a relatively high strength and toughness.
The toughness of the mold, mainly depends on the material itself, a carbon content, grain, as well as its organizational state and its inclusion content and strength.
Next to say, for the powder metallurgy mold processing materials, in fact, we should pay attention to it should have a certain high temperature performance. This is because when the mold temperature increases, will lead to the hardness and strength of the decline, so that the mold will appear early wear or plastic deformation and failure. In view of this, when choosing the mold material, it should be noted that it should have a relatively high resistance to tempering stability.
Finally, on the powder metallurgy mold processing materials, we must pay attention to it must maintain a resistance to hot and cold fatigue performance. This is because, in the actual application, we actually will note that the hot and cold fatigue is hot powder metallurgy mold failure is one of the main forms, it is precisely because of this, we in the processing of such mold Time, should have a relatively high resistance to hot and cold fatigue can be.
