A high-strength, low-alloy structural steel plate utilized primarily in the manufacture of bridges. Chapel Steel stocks A709 Grade 36, A709 Grade 50 and A709 Grade 50W. These grades are often specified with Charpy tests referencing the specific zone or lowest anticipated service temperature. The Charpy tests are specified as non-fracture critical, which is a per-heat test (frequency "H"), or fracture critical, ASTM A36, ASTM A 572, ASTM A 573, ASTM - BBN SHIP These grades are often specified with charpy tests referencing the specific zone (or climatic region) in which the bridge will be in use. Bridge steels can also be ordered to the ASSHTO M270 Spec referenced as AASHTO M270 Grade 36, AASHTO M270 Grade 50, AASHTO M270 Grade 50W.
