In the process of using stainless steel casting, its mechanical properties are higher than that of cast iron, but the properties of cast iron of such materials are worse. The melting point of stainless steel casting is higher than that of other materials in the process of production. In the process of processing, the molten steel is prone to oxidation.

Stainless steel casting in the process of processing need to pay attention to many problems, mainly because of the poor flow performance of molten steel, in the process of processing, in order to prevent the steel casting from insufficient pouring or cold shut, the wall thickness of steel casting can not be less than 8 mm

The structural force of the gating system of stainless steel casting is very simple. If the cross-section size of the equipment is large in the process of use, hot casting mold or dry casting mold can be used in the process of processing.

Stainless steel casting needs to properly improve its pouring temperature, generally it needs to be at 1600 degrees, mainly because the pouring temperature is high, and the excess degree of molten steel is large, so the liquid steel can be kept for a long time to a certain extent, so that the flow performance of liquid steel can be improved very well.

If the pouring temperature of stainless steel casting is too high, it will directly cause defects such as coarse particles and hot cracking. Therefore, in general, the pouring temperature of small castings with thin wall and complex shape is about the melting point temperature of steel + 150 ℃.

Stainless steel casting in the production process, in order to prevent its equipment cracks and shrinkage cavity phenomenon, in the process of production, we need to take measures, in the process of processing, we must make the product wall thickness uniform, and avoid its sharp angle and right angle structure.
