Stainless Steel Casting

What is Stainless Steel Casting

Lost wax Investment casting is the most precise casting method to manufacture stainless steel casting. Especially those irregular or complex structures products. So stainless steel investment casting is almost equal to stainless steel precision casting.

The stainless steel casting process contains several steps as below: mold making, wax model making, tree assembly, dipping and dewaxing, pouring, etc.

Advantage of Stainless Steel Casting

Stainless steel is one of the most common investment casting materials for two reasons. Stainless steel is very friendly to the investment casting process. Stainless steel fills out the sand tree’s extremely well leaving great detail and minimal voids. Another reason stainless steel is so popular is due to the high expense of the stainless steel raw material. Because investment casting allows the customer to have very little waste of raw material it reduces overall costs compared to machining by eliminating scrap. Machining a similar part can produce significant waste depending on the part, greatly increasing overall cost. Stainless steel investment castings can produce near net shapes with very little secondary operations required.

Application of Stainless Steel Casting

For metal castings requiring corrosion resistance and high strength, especially those in severe environments. stainless steel casting is an ideal choice. Below are the main applications of stainless steel casting:

Mining, Agriculture, Energy, Military, Machine Tool, Valve bodies, Pumps, Housings, Gears, Bushings, Handles, Marine equipment, Medical devices.
