What Is Stainless Steel Casting?

Stainless steel casting, also called stainless steel investment casting, refers to the formation of ceramics around a wax pattern to form a shell for casting stainless steel. Once wax patterns are created, they are melted into the gate system, immersed in slurry and sand to form a layered shell, and then replaced by molten stainless steel.

 

How are Stainless Steel Castings Made?

Stainless steel casting involves creating an original wax model, building the image with plaster and successive layers until a strong shell surrounds the model. After melting the wax, pour the molten stainless steel into the mold to create a perfect replica of the original wax pattern. Stainless steel casting provides economical undercutting, high resolution, sophisticated detail and smooth surface finish compared to machining separations.

In most cases, stainless steel casting is the only way the part can be made economically.

Stainless Steel Casting Material Information

 

Material

Grade

Common Application

Stainless Steel

304

Housings, bodies. SS304 is widely used in medical, plumbing, watering, mining and petrochemical industries as the standard for cleanliness as well as corrosion resistance.

 

316

Housings, gears, plates. Superior corrosion resistance of SS316 makes it ideal for many applications including automotive, food & diary and petrochemical environments.

 

304L/316L

Similar to other 300 series steel, low carbon makes it softer but more corrosion resistant. Ideal industries are such as food & dairy, medical and petrochemical.

 

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. Ideal industries are automotive, food & dairy and various machine tools.

 

17-4

Very strong. Can be used in military, various machine tools etc.
