--Dear experts,I am conducting a PQR for ASTM A 519 Gr 4130 QT pipe material.When I checked A519 standard it is giving the tensile strength values for 4 conditions only. Hot rolled/stress relieved/Annealed/Normalised.But in the material mtc I cannot find any details regarding the condition. It is given as Quench tempered only. The UTS of the parent material in mtc is 728mpa. As per PWPS I have done PWHT after welding. When I did the tensile test ; ductile fracture occured in the parent material with a UTS of 683.What is the minimum tensile strength required for the PQR to get accepted?Regards,Jose
