Hardness Values


Would anyone happen to know the hardness values (Brinell or Vickers would be great) for steel grades S235 and S255?
Any help would be appreciated.

Hello Jean-Claude

Not enough information given - which code or standard, specification and condition are you interested in.

Wild [educated] guess for hardness: assuming carbon steel with a maximum tensile of 70ksi/ 500 MPa, the hardness should be a HB [brinnell 3000 kg] of about 200.
