What are the testing methods for stainless steel precision casting?

1. The manufacturing process can be partially automated to save manpower and increase the production rate;

2. The production cost is low; castings have high dimensional accuracy and fine surface roughness values. The dimensional accuracy of castings can reach 4-6 grades, and the surface roughness can reach 0.4-3.2μm, which can greatly reduce the machining allowance of castings;

3. Better dimensional stability;

4. The pottery shell mold is thin, and the cooling rate of the casting after pouring is high and uniform, so its mechanical properties are better;

Due to the high pouring temperature of stainless steel precision casting, its molten steel has a high degree of overheating. It needs to be kept liquid for a long time during use. Its fluidity can be improved during use, which directly causes coarse grains and hot cracks. And other defects.

Due to the poor fluidity of molten steel in stainless steel precision casting, in order to effectively prevent the cold barrier and insufficient pouring of the cast steel during use, the thickness of the cast steel should not be less than 8mm, and it is difficult to use other methods to process Castings.

When all of us are inspecting stainless steel precision registration, we can operate according to the above inspection methods, use stainless steel precision casting for correct operation, and correctly inspect, we can operate and use according to the above inspection methods.
