HARNESSING PRECISION WITH FETTA LOST WAX CASTING
Stainless steel investment casting is a manufacturing process used to create intricate stainless steel parts. It involves creating a wax pattern, coating it in a ceramic material to form a mold, and then melting out the wax. Molten stainless steel is poured into the ceramic mold, and once solidified, the ceramic is removed, leaving behind the cast part.
This method allows for high precision and is utilized in various industries like aerospace and automotive for its ability to create complex shapes with excellent surface finishes.
Superior corrosion resistance
Excellent surface finish
High dimensional accuracy
Extremely intricate parts are castable
Almost any metal Can be cast
No flash or parting lines


| Alloy | Common Usage | Applications |
|---|---|---|
| 304 |
Food Grade Steel, Housings, Bodies 304 is widely accepted in the food industry as the standard for cleanliness as well as corrosion resistance. |
Medical, Mining, Petrochemical |
| 304L / 316L | Similar to other 300 series steel, the "L" stands for low carbon, making it softer but more corrosion resistant for each grade of material. | Food & Dairy, Medical, Petrochemical |
| 316 |
Housings, Gears, Plates 316 is known for its superior corrosion resistance, making it ideal for many uses including marine environments. |
Automotive, Petrochemical, Food & Dairy |
| 410 & 416 |
Housings, Bushings, Handles, Brackets 400 series steels are high strength and very machinable. They will tend to break rather than bend under intense pressure. |
Automotive, Machine Tool, Food & Dairy |
| 17-4 |
Rods, Pins, Links, Arms 17-4 is the strongest of the stainless steel family and is used on parts that cannot bend. |
Military, Medical, Machine Tool |
| Duplex | Duplex is widely accepted for applications requiring high strength and excellent corrosion resistance. It is designed to combine improved resistance to stress corrosion cracking, pitting and crevice corrosion. | Food, Chemical, Oil & Gas |
| SUS 420 |
420 is an alteration of Grade 410 with higher carbon content to increase hardness, strength, and wear resistance. It is the highest level of hardness among all low chromium stainless steel, and has a scaling temperature of around 650°C. |
