Grades of Steel

12/31/2010 11:41 PM

Hi

I want to know about what EN stands for and how this number is calculated for strength of steel, how does it differ from Rockwell and Brinell Hardness

Don't know too much about it other than "EN" is the designation for the European standards. You can find more at this link: http://www.roymech.co.uk/Useful_Tables/Matter/Steel_Europe.html

A full discussion of this would be too lengthy for a Q/A forum. The various material qualities do not necessarily correlate closely to one another. They include:

tensile strength (ultimate)
tensile strength (yield)
percentage of elongation (at break)
compressive strength
shear strength
hardness (Brinell or Rockwell, or durometer for elastomers)
ductility
malleability
(notch) toughness

Many/most/all of these terms can be Web-searched for further information, and would also be explained in strength-of-materials textbooks.
