Revision of A320/A320M-22a Standard Specification for Alloy-Steel and Stainless Steel Bolting for Low-Temperature Service


Revision to align mechanical properties for A320/A320M-L7 Table 1 (inch and metric) with A193/A193M-B7 Table 2 (inch) and Table 3 (metric)
ASTM A193-B7 provides mechanical properties giving consideration to the diameter. As diameter increases Ts and Ys are reduced.
A320-L7 should provide the same considerations for diameter vs tensile strength and yield strength.
