A steel is considered to be stainless if it contains a minimal of 13% chromium.
Chromiun is the primary metallic element added to steel to make stainless steel.
There are many different kinds of stainless steel, but the most common alloying elements in it are chromium and nickel.

chromium or nickel
Steel is an alloy, and it is made from the elements ironand carbon. Other elements and combinations of elements can be added to the steel to change its properties to fit different applications, including :Chromium - improves durability and prevents rust (stainless steel).Nickel - increases durability and resistance to heat and acids.Manganese - increases strength and resistance to wear.Molybdenum - increases strength and resistance to heat.Tungsten - retains hardness at high temperatures.Vanadium - increases strength and springiness.
chromium added to regular steal form stainless steel.
No; steel is an iron-carbon alloy. Stainless steel is an alloy of steel with chromium added. Stainless steel is usually 13-25% chromium (by weight).
when wate ris adde to metallic oxide it forms a hard substance
All stainless steel has at least 10.5% Chromium in it. Chromium is what makes the steel stainless. The other elements in stainless steel can be nickel, nitrogen, molybdenum. You can find more information here: http://www.wisegeek.com/what-is-stainless-steel.htmIt is the incorporation of a good bit of chromium that makes steel into stainless steel. The presence of chromium in steel alloys allows them to resist chemical attack better than "regular" steels.Stainless steel contains chromium. The chromium forms a protective oxide layer on the metal surface. Even when scratched or cut, a new chromium oxide layer will form in stainless steel.

Chromium
Yellow is the main primary color in gold, mixed with a little red. A metallic element also needs to be added to make it gold.
Molybdenum
It is the 24th element. The confusion arises because it is the key alloying element added to steel to make it stainless.
No. Iron is a pure metallic element. Steel an alloy of iron iron with something else added, usually carbon, to give it more strength.
Yellow is the main primary color in gold, mixed with a little red. A metallic element also needs to be added to make it gold.
An alloy is when there are more than one elemnet present. So pure iron is not an alloy. If carbon is added to the iron that makes steel. If Chromium and Nickel are added that makes a grade of Austenitic Stainless steel which is thus an alloy not an element.
Steel with chroniuum added
why are other metals added to stainless steel
Steel is an alloy, and it is made from the elements ironand carbon. Other elements and combinations of elements can be added to the steel to change its properties to fit different applications, including :Chromium - improves durability and prevents rust (stainless steel).Nickel - increases durability and resistance to heat and acids.Manganese - increases strength and resistance to wear.Molybdenum - increases strength and resistance to heat.Tungsten - retains hardness at high temperatures.Vanadium - increases strength and springiness.
Steel is an alloy, consisting mostly of iron, with a carbon content between 0.2 % and 2.04%, depending on the grade and quality. Carbon is the most cost-effective alloying material for iron, but various other alloying elements are used such as manganese, chromium, vanadium and tungsten. so the active ingredient in steel is iron
