ASTM A establishes either a diameter or thickness range for the mechanical properties on table 3 for the different classes of steel. ASTM A applies to rings a product form that are either forged or rolled. In this case, thickness or diameter limitations aatm not applicable for tensile and impact property test requirements in Table 3.
Brinell Hardness testing is required 7.
A219 it mean that regardless the thickness of my forgingI can only estimate mechanical properties through the HB figures? There is no estimating of mechanical properties. The hardness testing is a validation of heat treatment. Am I correct if I say that the only difference between the 2 Stds. And if the above-mentioned question is truewhat would be the difference in designing a forging based on the technical attributes of either one or the other?
A921 there any violation in designing a ring forge a2291 per ? You really can do what you want, but if it was up to me I would use the specifications as intended. These specifications were developed for optimum gear performance. Now note the correlation between chemistries in Table 1 of each spec. So, first design the small diameter Pinions, Gears and Shafts per A, then choose a matching alloy in Table 1 of A for the large a921 ring gear.
This is merely a shortcut or guide; you still need to do the calculations to confirm.
But, the ASTM committee forces some thinking in order to handle the exceptional cases. Also, one has the option to make the more easily replaced part of an assembly somewhat softer to save on eventual maintainance.
