Aguinaldo: Your question is not easily answered without knowledge of the following information: the shape and size of the casting, the location of the gates and risers, the pouring temperatures, the location of the microporosity, etc. If you are having a systemic problem with casting SS, you should consult with a local expert in foundry technology.
