Want this question answered?
why are other metals added to stainless steel
Naturally occurring (it is an element), the metal occurs naturally in its pure, free form (native silver), as an alloy with gold and other metals, and in minerals such as argentite and chlorargyrite.
Stainless steel is better than other metals because they do not stain, rust, chip or their color fades. They are more expensive than other grills but lasts so much longer.
The iron ore is refined into iron, The molten iron is then alloyed (mixed) with other molten metals, commonly chromium and nickel, along with carbon. There are different mixes to produce stainless steel with different properties. It is not truly stainless, but is stain RESISTANT and rust RESISTANT.

why are other metals added to stainless steel
To make it last for a long time
Stainless Steel must have at least 10.5-11% chromium content.
The addition of other metals makes steel stainless.
Steel is just a form of iron that is refined differently to iron in a blast furnace, as it is allowed to have a small amount of carbon and other alloying metals. However other forms of steel such as weathering steel and stainless steel have other metals (chromium, magnesium etc.) added to them to give them the properties that they require for their particular purpose.
Stainless steel does not corrode like other metals do. because of the tannic acid in cedar and the fact that it will be outdoors stainless steel will resist corrision much better.
The benefits of stainless steel materials are that they will not rust as other steels would. Additionally, steel is a lot more common than some other metals.
stainless steel
Oversimplifying it alot: Iron + Carbon --> High Carbon Steel High Carbon Steel + Chromium & other surface alloy metals --> Stainless Steel Basically Stainless Steel is ordinary Steel with a surface Chrome Steel layer protecting it from corrosion.
Chromium and nickel are metals mixed with iron. Carbon is also added.
Because it is made from iron and other metals such as nickel for example depending on the grade of stainless steel. the reason the steel is stainless is because the outside of the steel is protected by the non ferrous layers that will replace as it is scratched or worn of.
Well, the answer lies in the question; by saying 'real' stainless steel, you are implying that there are fake metals which go under the name 'stainless steel', thus the difference is that the stainless steel in refigerators is actually stainless steel, and the fake stainless steel is not...thus your question is answered...
