Believe a lot of people at the time of using the lost wax casting process has met the casting occurred the phenomenon of brittle fracture, so if meet how are we to avoid such phenomenon occurs and find out the reason of the brittle fracture occurred?Lost wax casting when stainless steel castings in hulling, mechanical processing, and in the process of installation, often attack (namely) of brittle fracture to brittle fracture phenomenon.In case of this problem, will make the whole furnace casting scrap, cause there are many reasons for this phenomenon, we should understand that in the process of production causes for brittle fracture of the lost wax casting stainless steel castings, and can effectively control the occurrence of brittle fracture.
