In the process of using stainless steel precision casting, its mechanical properties are higher than cast iron, but this material has poor cast iron properties and has a higher melting point than other materials.
There are a lot of problems that need to be paid attention to in the process of processing, mainly because the fluidity of molten steel is relatively poor. The wall thickness of steel parts cannot be less than 8mm.
The structural force of the gating system is relatively simple. If the cross-sectional size of the equipment in the process of use is larger than that of cast iron, the hot casting or dry casting can also be used in the process of processing.
The temperature guarantees the good fluidity of the melt during the transfer process. The selection of stainless steel precision casting temperature should be determined according to the transfer distance, the cooling situation during the transfer process, alloy, specification, flow rate and other factors. The stainless steel precision casting temperature is higher than the alloy liquidus. The temperature is 50 to 110°C higher.
The production temperature can ensure that the melt will have good fluidity during the transfer process. The equipment needs to be determined according to some factors such as the transfer distance and the temperature drop during the transfer process during the process of selecting its casting temperature.
The crack tendency of stainless steel precision casting is relatively low. During the use process, it is necessary to ensure that its alloy has its good exhaust gas feeding ability, so that the conditions of sequential crystallization can be created, so that its density can be increased. In general The temperature of the lower casting will be higher.
