Stainless Steel Investment Casting

The stainless steel has much better physical properties then iron and normal
steel, but it possesses worse casting properties. Because the stainless steel
has higher melting temperature point, by the liquid form it has worse
flowability and bigger shrinkage ratio, and more easier to be oxidized. To
prevent the happening of defects such as crack, sand stick, under-pounding
etc., a series of more complicated technics are applied in the casting, thus
the success rate of casting stainless steel is able to greatly be improved.

The Features of stainless steel precision casting
Take higher metal temperature reach to 1520~1600℃. For the small and
complicated structure part keep the pouring temperature to melting point
+150℃; for the big and thick wall part keep the pouring temperature to melting
point +100℃;

Make bigger and simpler gating tunnel;

Use dry or heated casting mold;

Make sure the casting product wall thickness is as even as possible and over
8mm, optimize the part structure in sharp corner and edge;

Improve air permeability and passing ability by using hollow mold core or oil-
sand core, or add coke with it.

The Notice of Stainless Steel Investment Casting:
For the material used to create the mold shell, similar to the iron casting
somehow, the stainless steel casting china also uses silica sol and water
glass as the adhesive material.
