How the steel really looks like....

Steel. Material that we use everyday but don't we care how it really looks like? We had made experiment during material lab and found that the steel actually possess grains on its surface and the size of grains determines the strength of the steel. Take a look of the image acquired by lab's microscope with 500x optical zoom. We draw the red line in order to measure the grain size of the low carbon steel.
