Introduction聽
The mechanical properties of ss 304 investment casting are higher than those of cast iron, but their casting properties are worse than those of cast iron. Due to the high melting point of stainless steel precision casting, molten steel is easy to oxidize, and has poor fluidity and large shrinkage. Its body shrinkage rate is 10-14%, and the linear shrinkage rate is 1.8-2.5%. In order to prevent defects such as http://www.castingcncmachining.....com/precision-casti
