Decided finally to ignore the Caps

The hardness of En8 (having quite high C - 0.40%) will be dependent upon the supply condition - Annealed, Hardened, HT etc and may vary between say about 150 BHN to 40 HRC

The following may help you

http://www.matweb.com/search/datasheet.aspx?matguid=1e96358ad933489eb1e1f6a0a53b4d09&ckck=1

http://www.portlandsteel.com/Specs_&_Applications.pdf

Als pl check up AISI 1040 Steel

In fact for these steels (or any other) why are you looking for hardness ? we try to gauge then by UTS,YS,%E, RA etc (and additionally impact wherever needed)

Hardness always we treat as additional information (and is usually resorted to as an approximation when you can not due to some reason carry out mech test)

for eample have a look at this site

http://www.calce.umd.edu/general/Facilities/Hardness_ad_.htm#6

but we as a rule do not go by these charts (more of empirical relationships) and depend more on the sample test.

DEAR PEOPLE Hardness is typically 200HB; ref: previous answer and why you want to control hardness. Hardness is related to the material's susceptibility to Hydrogen embrittlement, so is important if you are e.g. using the material underwater with cathodic protection. WITH THE VERY BEST OF KIND REGARDS, HARDNESS
