SB127 N04400 head forming - heat treatment?

SB127 N04400 head forming - heat treatment?

SB127 N04400 head forming - heat treatment?

(OP)
Head:
material: SB127 UNS N04400
thk (after forming) > 6mm
ID: 305mm
Code: ASME (U stamp)

Question: after COLD forming, shall I need any heat treatment?  Normalizing? Which temperature?
Where I can find some information?

Thank you.

RE: SB127 N04400 head forming - heat treatment?

No, according to my review of ASME Section VIII, Div 1, Part UCL, specifically UCL-77 and 79.

RE: SB127 N04400 head forming - heat treatment?

(OP)
Sorry but I my ASME Review (2006) UCL stop at 60.
And why UCL ? UCL refers to integral cladding, overlay cladding and linings... and this is not my case.


RE: SB127 N04400 head forming - heat treatment?

(OP)
Maybe you refers to UNF-75 AND 79, but there I can't find any mandatory sentence about n04400.
Could you help me?
Thank you.

RE: SB127 N04400 head forming - heat treatment?

Yes, it is UNF not UCL, sorry about the confusion. That is correct, the nonferrous nickel-base alloys with the exception of a few alloys in Table UNF-79 do not need a post forming heat treatment. Are you aware that this material by ASME SB-127 can be supplied in annealed or cold rolled conditions?

RE: SB127 N04400 head forming - heat treatment?

(OP)
Thanks.
The material (plate) was supplied as "hot rolled + soft annealed", is there any results?
Shall I point to my head former supplier something?


RE: SB127 N04400 head forming - heat treatment?

marsich;
What are you asking? Do you have a copy of ASME SB-127 to review the mechanical property requirements in Table 3? Have you ever worked with Monel alloys? I have provided the web site below to research the information on Monel 400

No, it's my first experience with nikel alloy.
Thank you for the link.
Now I realized smile
