Best Stainless Steel Garbage Disposals

There are great options for stainless steel garbage disposals. These will work great and get rid of the food that needs to be disposed of.

The best stainless steel garbage disposals are the InSinkErator Evolution Excel, the Evolution Septic Assist, the Supreme SS Garbage Disposal, the Evolution Esteem Plus, and the InSinkErator Evolution Prestige. These garbage disposals all have stainless steel grinding chambers that function well.

Unfortunately, no garbage disposals are made of 100% stainless steel. However, if a manufacturer says his garbage disposal is made of stainless steel, it simply means that its grinding chamber, as well as the grinding components, are made of stainless steel.

Stainless Steel vs. Galvanized Steel

Why use stainless steel? Using stainless steel gives some great benefits. As the name says, it is stained ‘less’, so it is resistant to corrosion and stain. Garbage disposals that are made of stainless steel are expected to last much longer than ones that don’t have stainless steel components.

For those not familiar with metallurgy, there are different types of steel, but only two are relevant to us here, and they are stainless steel and galvanized steel.

Steel is an alloy of carbon and iron. When you add a bit of chromium to steel (11% to be exact), it becomes stainless steel.

When you dip steel in molten zinc, it gets a zinc coating. The combination of both of these metals is called galvanized steel.

The grinding chambers of most garbage disposals are made of either galvanized steel or high-quality plastic. But all their grinding components are stainless steel.

Then what disposals qualify to be called stainless steel disposals?

Generally, stainless steel garbage disposals are those disposals whose grinding chamber, as well as grinding components, are made of stainless steel.

Stainless steel garbage disposals are highly resistant to corrosion and hence they are durable. However, they are also expensive. The garbage disposals that are made of stainless steel are usually the top-end models, and so far only the Evolution series by InSinkErator have them.
