high speed steel grades

Steel — Alloy Property/ Reason for alloying uses Stainless steel (Fe, C, Ni, Cr) Lustrous, resistant to corrosion, high tensile strength Alloy: Acquires brilliant silvery shine on alloying with Ni, Cr Utensils, cutlery, automobile parts ..

The speed of sound in steel is 5,200 meters per second and the speed of sound in air is 330 meters per second. Find the fraction of speed of sound in air to the speed of sound in steel. => 1 / 520 or 330 / 520 or 33 / 520 or No..

Carbon content of steel is between 0.1 and 1.5%. This is intermediate between cast iron and wrought iron. The hardness of steel increases with increase in carbon content. Steel contains other elements like manganese, chromium, silicon, nickel, tungsten, vanadium, and m..

Iron gets magnetized faster but loses its magnetism as soon as the inducing magnet is removed. Hence soft iron is said to have high susceptibility but low retentivity. This property of soft iron is very useful in making temporary electromagnets where we need strong but temporary magnets. ..

The flash of lightning due to collision of clouds is seen much before the thunder, although both occur simultaneously. This happens because the velocity of light is greater than the velocity of sound. The speed of sound depends on the properties of the medium through which it travels. ..

On plotting a fraction of molecules having different speeds against the speeds of the molecules (along x-axis) a curve known as Maxwell's distribution curve is obtained. The important features of which are: The fraction of molecules with very low or very high spee..

Speed - In an athletic meet different participants start running at the same time and cover the same distance. The person who takes the minimum time to cover the distance will be judged as the winner. Suppose Ram and Krishna take 20 minutes and 10 minutes respectively to cover a distance ..

Speed - Ram and Krishna run in different races covering different distances. Ram takes 20 minutes to cover 1000 m and Krishna takes 10 minutes to cover 700 m. Who is faster? To find out who is faster we shall calculate the distance covered by them in one minute. Krishna covered more dista..
