Everybody in the spreading market understands a reality. That is the mechanical residential properties of stainless steel spreading are greater than that of cast iron, yet its spreading efficiency is worse than that of cast iron. Stainless steel casting comes from financial investment or precision spreading, with reasonably high melting point. The molten steel is easily oxidized, due to inadequate fluidness and also huge contraction price. From an useful perspective, stainless-steel casting is suitable for spreading of different types and alloys.

Benefits and disadvantages of the stainless-steel casting process are as listed below:

First, due to the inadequate liquidity of the liquified steel, the wall surface density of the steel castings should not be less than 8 mm, in order to prevent the cool shut and also misrun. The structure of the putting system makes every effort to be basic, and the sectional dimension is larger than that of actors iron. Adopt dry spreading or hot casting, as well as the spreading temperature level must be suitably boosted to 1520-1600. The fluidness can be boosted given that the casting temperature level is high with huge superheat, thus the liquid stays for a very long time.

Nevertheless, if the pouring temperature level is too expensive, it will cause flaws such as crude grains, hot cracks, pores as well as sand burning. For iron casting OEM , the casting temperature level of tiny, thin-walled and complex casting ought to go to the melting point +150; and also of big, thick-walled casting +100.

We need to take these steps to prevent the incident of shrinking openings and also cracks in stainless-steel castings. 1. Making the wall surface thickness uniform, as well as avoid sharp as well as appropriate angle structures, 2. Adding sawdust to sand mold, as well as coke to sand core. 3. Taking on hollow sand core and oil sand core to transform the deformability as well as leaks in the structure of the sand mold and core.
