Typically steels undergoing PWHT can tolerate higher C.E (refer page-3 of this catalogue), based on the industry experience. C.E could be controlled  to get balanced chemistry  same time without sacrificing through thickness properties of steel.   You may find further requirements on C.E in the latest spec of  SA-516 in ASME Sec-II , Part-C.   As mentioned below simulation temperature @ 6900C looks quite high for C-steel. Usually alloying elements other than C, Mn are required to provide the basic mechanical properties in the steel at this temperature. Typically soak temperature of C-Mn steel seldom would exceed   6400C.   Thanks.     Pradip Goswami,P.Eng 88,Garth Trails Crescent Hamilton,Ontario, L9B2X1,Canada Email-pgoswami@sympatico.ca Email-pgoswami@quickclic.net Tel-905-679-9677 From: sachin sankhe [mailto:sachin.sankhe@rediffmail.com] Sent: None To: materials-welding@googlegroups.com Subject:   Dear Friends I have got query details are as follows 1.MOC-SA516 Gr.70 2.Application-Reactor Regenertaor Package for FCC unit 3.Thickness Range-50 mm to 100 mm 4.Carbon Equivalent limitation-0.43 5.Simulation Requirment-690 Deg.
