"Typical" Charpy V Notch results on ASTM A709 Gr. 50 m270 grade 50w

Jun 22, 2011 · Perhaps for Grade 50W Type A, but not standard Grade 50. The standard Grade 50 will only be normalized or TMCP rolled, and does not contain the alloy elements (Cr, Ni, Mo) that Grade 50W Type A does, so the CVN will be lower, especially at - 40 C. Figure 2.3.1 from the following link shows typical results for Grade 50 (50W on the graph) and m270 grade 50w751.3 Structural Steel Design Properties - Engineering m270 grade 50wMay 17, 2019 · All structural steel will be AASHTO M270 ASTM A709 Grade 36 (F y = 36 ksi) or Grade 50 (F y = 50 ksi) and structural steel HP piling will be AASHTO M270 ASTM A709 Grade 50S (F y = 50 ksi) except where weathering steel (AASHTO M270 ASTM A709 Grade 50W steel) is indicated on the Design Layout or in special cases.
