Hi,
I'm looking to come up with a machining time estimate to mill some CS Plate (A516-70). I need to face/shoulder mill off a "1/4 moon" shape of about 104 sq. in. by 1" deep. The only shoulder milling is around a 5" radius for about 270 degrees. The rest is all face mill. If it make it easier...
Any ideas on how I can fillet the intersection of the two pipes? If I split the part in half by cutting at the centerline it fillets fine. But then my mirror to remake the part fails.
Thanks

Environmental conditions:
Hydrogen, propane, methane
220 ppmv H2S
350 psig, 800F
I'm looking for expected corrosion rates of A516-70 Carbon Steel plate, normalized
over a 6 month period.
Other materials which I don't think will be any issue will be stellite 6, nitronic 60, Inconel 718, Inconel...
I have a couple of questions on the HT procedure for the 1700-1850 F Anneal and age that is in the Huntington Alloys book (attached).
As I understand the directions they say to
step 1) anneal at 1700-1850F
step 2) cool
step 3) aged at 1325F/8Hrs
step 4) cool to 1150F
step 5) age at 1150F total...
I looking to design some equipment that will be working in the following environment.
800-1,000 deg F
free sodium, Sodium Oxide, and Sodium Hydroxide, Ti-metal and NaCl (salt) mixture - all four are possible.
I need some guidance in corrosion compatibility for some high strength and wear...
My client wants A516-70 plates that have been rolled and welded to be re-normalized after welding.
The dimensions are about 40" ID X 1.5" wall x 8" long. Can anyone please point me to a spec that would provide the necessary temperature, holding time, heating/cooling rates, etc.?
Thanks.
