The Brinell hardness of a steel sample was measured to be HB

The Brinell hardness of a steel sample was measured to be HB=250 kg/mm2. Approximate the material’s tensile strength. Convert the Brinell hardness number to a) Vickers hardness number and b) Rockwell C hardness number. Relatively speaking, would you consider this material soft, medium hard, hard, extremely hard or “I am clueless!.”

Solution

As per hardness conversion chart Vickers hardness no. 251

And Rockwell c hardness no is 25

Material is hard
