Colleagues,
CS materials like ASTM A106-B, ASTM A105, A234 WPB, A672 CC60/70, ASTM A516 Gr 60/70 or ASTM A216 WCB, based ASME B31.3, Table A-1, have a lower temperature limit -29 deg C, the requirement of impact test for application under -29 deg C will be based on para 323.2.2.
Do you have experience in using the above materials on operating temperature below 0 deg C (Some of you may have minus ambient temperature) or near to the temperature limit without impact testing. Did you find the possibility of ductile-brittel transition on temperatures above?
Regards,
