why are other metals added to stainless steel
Most nails today are made of steel. Steel is mostly made out of iron but has some carbon and other materials added to enhance strength and resist rust.
mixture
Alloys are "mixtures" of metals or non-metals in metals. They are developed to create new characteristics of the metals. Carbon (and other things) added to iron makes steel. Precise mixtures makes different sorts of steel alloy. Steel is stronger than iron and can have many characteristics which give superior properties for specific purposes. There is a virtual infinite number of alloys which could be made. Not all will have useful characteristics.
alloys because they are a combination of metals for example steel is acombination of iron and other metals
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.
cocret and woods. also various metals of stanless steel.
To make it last for a long time
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.

Pure iron is too soft for many uses. Different metals are added in order to strengthen the steel and make it harder.
Steel is an iron alloy. When the alloy contains chromium and phosphorous it doesnot rust. Other metals may be added for improved strength and heat resistance.
Steel could be a man-made material, a natural material is one which nothing has been added to it to make it react/ behave differently. steel could be natural if its just steel that has had the carbon in it reduced to make it purer. but most often steel has had various other metals added like chromium.

strength versus cost of steel against otehr metals
Most nails today are made of steel. Steel is mostly made out of iron but has some carbon and other materials added to enhance strength and resist rust.
The addition of other metals makes steel stainless.
Steel is made of iron to which is added between 0,02 % and 1.67 % of carbon.If you go over 2% of carbon, you'll get cast iron instead of steel.
