AGMA material grades
I am trying to carryout gear design using AGMA method, but that includes finding allowable stress as a function of the material's Brinell hardness. Now the equation for that is different for each AGMA grade of steel(Grade 1,2 and 3). I tried to search a lot what these grades are and how the steels are classified to these grades, but no success. Please help me.
