Nanoscale Size Perspective
How small is a nanometer?
NanoSteel’s patented Super Hard Steel® (SHS) alloys feature microstructures refined to a nanoscale, a length of scale which is defined as 1 to 100 nanometers.
 
Grains refined to a nanoscale in the microstructures of SHS HVOF and TWAS thermal spray coatings can only be seen through the lens of an electron microscope.
 
In the amount of time that it took you to read this page, your fingernails each grew one nanometer in length!
