Because stainless steel castings have excellent corrosion resistance and oxidation resistance, they are often used in various medium corrosion conditions, so in manufacturing, we must be very strict and careful, otherwise, the casting with unqualified quality will be corroded and destroyed in a long time in the corrosive medium, and will not play any effective role. Then the following edition focuses on the points needing attention in manufacturing, such as: 1. In order to prevent whitening in casting stainless steel, besides measures to be taken in technology, stainless steel with thicker wall is also needed to ensure that similar phenomena do not occur in the use of stainless steel castings. 2. In order to make stainless steel castings easy to extract, the casting inclination of stainless steel castings should be larger than that of sand castings, and the casting inclination is related not only to the types of alloys, but also to the position of the surface and the height of the wall of the castings. 3. Because the heat dissipation rate of metal mold is faster than that of other materials, the minimum wall thickness of stainless steel castings should be a little larger than that of sand castings. Only by rigorous treatment and operation of the manufacturing steps can we produce stainless steel castings of high quality, and make the products shine brightly in their application and display excellent anti-corrosion and anti-oxidation characteristics.
