In the process of using, the mechanical properties of stainless steel precision casting are higher than those of cast iron, but the properties of cast iron of such materials will be worse. In the process of manufacturing, the melting point of stainless steel precision casting is higher than that of other materials.
There are many problems that need to be paid attention to in the processing of stainless steel precision casting, mainly because the flow performance of molten steel is relatively poor. In the process of processing, in order to prevent insufficient pouring or cold insulation of steel castings, the wall thickness of steel castings should not be less than 8mm.
The structural force of the gating system of stainless steel precision casting is very simple. In the process of use, the section size of the equipment should be larger than that of cast iron, so its hot mold or dry mold can also be used in the process of processing.
The stainless steel precision casting temperature ensures the good fluidity of the melt in the transfer process. The selection of stainless steel precision casting temperature should be determined according to the transfer distance, cooling in the transfer process, alloy, specification, flow and other factors. The stainless steel precision casting temperature is 50 to 110 ℃ higher than the alloy liquidus temperature.
The manufacturing temperature of stainless steel precision casting can effectively ensure that its melt will have good fluidity in the process of transfer injection to a certain extent. In the process of selecting its casting temperature, the equipment needs to be determined according to some factors such as the distance of transfer injection and the cooling in the process of transfer injection
The crack tendency of stainless steel precision casting is relatively low. In the process of use, it is necessary to effectively ensure that its alloy has its good ability of exhaust feeding, so as to create the conditions of sequential crystallization to a certain extent, so as to improve its density. Generally, the casting temperature will be high.
