What is Duplex Stainless Steel Casting? Duplex Stainless Steel Casting is the investment casting process using duplex stainless steel as the material. Duplex stainless steel is called “duplex” because they have a two-phase microstructure consisting of grains of ferritic and austenitic stainless steel. The picture shows the yellow austenitic phase as “islands” surrounded by the blue ferritic phase. When duplex stainless steel is melted it solidifies from the liquid phase to a completely ferritic structure. As the material cools to…

What is Stainless Steel Casting? Stainless steel casting is the special steel casting type used primarily because of their corrosion resistance. All stainless steels casting grades contain a minimum percentage of 10.5% chromium. Chromium is always the deciding factor, although other elements, particularly nickel and molybdenum, are added to improve corrosion resistance of stainless steel casting components. The success of the material is based on the fact that it has one unique advantage. The chromium in the stainless steel has…

When you are looking to source stainless steel castings for your manufacturing project or for any other purpose, it is important to keep in mind the following considerations before deciding on your foundry supplier. This post aims to functions as a buyer’s guide while engaging in stainless steel casting purchases. The top considerations are: selecting the stainless steel foundry, relationship between the foundry and buyer, foundry costs and quotations received. Let’s look at these points in detail. Sourcing the Stainless Steel Foundry:…

The method of the investment casting allows producing complex shaped stainless steel castings with small dimensional tolerances and excellent surface quality. The big advantage is the production of stainless steel castings from materials will probably avoid further machining operation. Using a different technology would result in high costs, or their production would be impossible. In comparison with machining, the dimensional accuracy of stainless steel castings produced by investment casting cannot be compared, even though when compared with other methods of casting…

When completing stainless steel casting process, we may found that the surface of some stainless steel castings are smooth, but some look a bit rough. So what caused the difference? Here we would like to analysize the reasons that may affect the surface roughness of stainless steel castings. 1. Surface Quality of Stainless Steel The stainless steel is made of columnar crystal structure mesh, and the refractory materials, additives and water are filled in the middle, so that there are…
