FW: Re: [MW:14989] Stress relieving of 410S

Dear Sir,
Thanks for your reply.
Actually my issue is not related to welding of 410S.
What will be soaking temperature after explosion bonding i.e.cladding of SA 516 Gr 70+ SA 240 Tp 410S.

Thanks and Regards

which electrode are u using for this purpose..i think it'z not
E309..if u r using E 410-XX electrode for welding, then heat to
730-760°C and hold for one hour before cooling it to ambient
temperature.. Refer SFA 5.4 Table 6..
