Because the mechanical properties of stainless steel precision casting are higher than those of cast iron, but its casting performance is worse than that of cast iron, so it belongs to investment precision casting or precision casting. It has a relatively high melting point, the molten steel is easy to oxidize, the fluidity of molten steel is poor, and the shrinkage is large.
Stainless steel precision casting is not only suitable for the casting of various types and alloys.
In order to prevent stainless steel castings from having shrinkage cavity, shrinkage porosity, pores and crack defects, the wall thickness should be uniform, avoid sharp corners and right-angle structures, add sawdust to the molding sand in the mold, add coke to the core, and use hollow cores and oil sand cores, etc. to improve the yieldability and permeability of the sand mold or core.
