Steel and iron can be distinguished by looking at the brightness, smoothness and listening to the sound of percussion.
Steel and iron are two different industrial materials, and finished products can be seen everywhere in life. How to distinguish steel from iron with naked eyes? Let’s give you a specific introduction.
Details
01
Look at the brightness of the material surface: the general steel surface will shine, in the sun will reflect, the iron surface is dark gray.
02
Judging by the smoothness: the steel surface is relatively smooth, but the iron surface is rough, there are obvious particles.
03
Different from the sound: After the collision of the steel, the sound of “just now” will make a “just now”. The sound is dull.
04
The biggest difference between steel and iron is that the manufacturing process is different. The carbon content in steel will be less than 2%, but the carbon content in iron is higher than 2%.
05
Steel and iron composition is different, the softness is not the same. Steel is more malleable and toughness is also better, iron is relatively poor in softness, mainly hard and brittle.
