摘要
Abstract
Mechanical pitting and pockmark defects are often founded on the surface of 400 series stainless steel casting by investment casting because of oxidation. A layer of graphite sand was added during the shell mold making process, which can make the reducing atmosphere between the steel melt and surface of the mold. The above measures can prevent the mechanical pitting and pockmark defects, ensure the yield of the castings, and improve production efficiency关键词
