The maximum cross-sectional area of hand forgings is 256 sq in.b Caution: This specific alloy, temper, and product form exhibits poor stress-corrosion cracking resistance in this grain direction. Itcorresponds to an SCC resistance rating of D, as indicated in Table 3.1.2.3.1(a).c Bearing values are “dry pin” values per Section 1.4.7.1.737169 b615957 b6159...44............942717068 b605856 b.........43............831696866 b585655 b.........41............731686665 b565554 b.........41............6313-358
