Hardness Values

Hello,

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.
Thanks.

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.
