The primary advantages of so-called high speed steels is in their ability to withstand heat created from the friction of a fast moving cutting tools such as drill bits or saw blades. They are formulated with specific alloys which make them heat resistant and more wear resistant than regular high carbon steels.
Alloys are made to change one or more physical characteristic of the base metal. Of these the most common is strength, but electrical and thermal conductivity, hardness, malleability, and reactivity are some of the other reasons. Alloying lets us control the properties of the final material.
The advent and widespread use of alloys has been an advantage to humanity for thousands of years. An alloy is the mixture of metals to create a final product of better strength and selected characteristics. Steel (from iron) and the gold in jewelry are major examples of alloy usefulness.
Alloys are important because their properties are often more superior to those of their component elements.
to makes the stronger ,harder metals and changesits apparence & makes it more resistant to corrosion. therefore alloying iron makes it more useful.

Alloys are so important because they enhance the functions of the metal, making it stronger or more useful in different situations.
ya what he said
they are stronger, less brittle because the particles are not arranged in neat rows, as in pure metal. .
They are hard with high melting point and are prevented from corrosion, as Steel, Brass, Bronze etc.
are created to enhance the property of the metal
The difference is percentage of carbon, the main alloy element. Those irons containing less than 2% carbon are known as steels while those containing more than 2% carbon are known as pig iron. Pig iron is obtained from iron ore by processing it with coke in a blast furnace. This pig iron is then further processed to reduce the carbon content in different furnaces to obtain steels. These steels can be then further processed to obtain alloy steels, stainless steels by adding elements such as silicon, manganese, chromium, nickel, etc.
While stainless steel is an alloy of steel, the primary difference between stainless steel and other steels is that the stainless steels have a high percentage (about 10% or even more) of the element chromium in them.
carbon steels are steels which contain upto 2% carbon and some other trace elements such as silicon, manganese etc., Tool steels have greater amount of alloying than the alloy steels of iron. alloying elemnts include chromium, tungsten, molybdenum, carbon, vanadium, nitrogen in the form of nitrides, manganese, silicon, cobalt. These two mainly differ in the pattern in which they are manufactured. tool steels are manufactured from electric furnace techniques where as most carbon steels are manufactured from conventional melting processes. This is done to exhibit good alloy characteristics and impart greater refined structure which cannot be obtained from the conventional say a cuppola furnace or a bessemer furnace.
Stainless steels are produced in carefully controlled environments and have higher alloy contents-both of which bring up costs.
German Engineers developed the system for coding special alloy steels during the first world war. EN means Emergency Number.
The difference in classification of low alloy and high alloy steels is based on the metal composition: low alloy steels include a lower concentration of alloying metals versus high alloy steels. The composition affects properties like strength, ductility, etc.

ALL steels are "alloy steels." Steel consists of iron alloyed to other elements--carbon, manganese, chromium, vanadium...
Low alloy steels
Mostly iron. the "low" of the 'low alloy' can refer to both the carbon content and the prorprtion of other metals in the alloy.Alloy steels are broken down into two groups: low-alloy steels and high-alloy steels. The difference between the two is somewhat arbitrary: Smith and Hashemi define the difference at 4.0%, while Degarmo, et al., define it at 8.0%.

Ths cost of tool steel is dependent on many factors including the alloy content and the manufacturing cost. Low alloy tool steels can be boought for less than $2.00 per pound. High alloy tool steels and high speed steels are sold for as much as $30.00 per pound. See the related links below for more information about the cost of tool steels
Most stainless steels have a strenght of at least 500 MPa. Most alloy steels also have that strength.
