Steel qualities

  1. Jan 25, 2005 #1
    In a table of different steel qualities the information about a perticular type of steel can be as follows:

    Steel type:



    My question is, what do these values tell me? The values are in [tex]N/mm^2[/tex]

    While I'm not sure I understand what the numbers themselves represent, the approximate value of the quantities seems to be comparable to typical values for steel in MPa, which is the same as N/mm^2.

    So, my guess is YES.

    What is the format of the table form where these numbers originate?

    S235 is a conventional low carbon structural steel (European Standard EN 10025)

    Grades are:

    Yield strength should be about 235 MPa, UTS about 340-470 MPa.

    The maximum numbers may be maximum design stresses, but it is hard to tell. The numbers are given as ranges.

    I'd guess similarly to design stresses or then something more exotic, like allowable stress amplitudes in fatigue.

    Yeah, the 'plus or minus' seems to suggest fatigue related parameters.
