Chromiun is the primary metallic element added to steel to make stainless steel.
Yes, cobalt is sometimes added to stainless steel as a minor alloying element to improve strength and corrosion resistance. However, its presence is typically very small, with most stainless steels containing less than 1% cobalt.
Chromium is added to ordinary steel to improve its corrosion resistance, hardness, and strength. The formation of a thin oxide layer on the surface of steel, due to the presence of chromium, helps to protect it from rust and other forms of corrosion. This makes chromium an important alloying element in stainless steel production.
When water is added to a metallic oxide, it forms a metal hydroxide (also known as basic oxide) and releases heat in an exothermic reaction. For example, when water is added to calcium oxide, it forms calcium hydroxide.
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.
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!
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.
Yes, cobalt is sometimes added to stainless steel as a minor alloying element to improve strength and corrosion resistance. However, its presence is typically very small, with most stainless steels containing less than 1% cobalt.
No. Iron is a pure metallic element. Steel an alloy of iron iron with something else added, usually carbon, to give it more strength.
Steel with chroniuum added
why are other metals added to stainless steel
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.
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.
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
