Can I expect this steel to have good Charpy impact resistance down at sub-zero temperatures (say, -40 deg. F)? If so, why? I have been told A1011 was developed for Arctic applications, but I have not found any published references in my search . I do notice that impact testing is not among the requirements or supplemental requirements for A1011, unlike ASTM A36 (which is listed as an alternate material but data suggests poor impact resistance at low service temperatures).
