D-Monel Mech. Properties
(OP)
Hi all;
I've tried to find, unsuccesfully, the mechanical properties (tensile and yield mainly) for Monel, A494, Grade M-25S. The ASTM spec has no data for this alloy other than hardness. I believe the Federal Spec for this is QQ-N-288 Comp. D, but again no data. Hours of web searching for more info on this casting grade was a no-go.
Can anyone point me in a direction I haven't looked ??
Thanks,
Bob

This is the info I was looking for, curious the ASTM spec has chemical composition info but no mechanical props, I wonder why ? Anyway, I am trying to find a non-magnetic replacement for 15-15LC that I can cast ($ issue), and the foundry reccomended this, but had no info on it :)
Thanks again,
Bob

RE: D-Monel Mech. Properties
has 732 papers for "Nickel Copper."
The one below has the mechanical properties of Nickel-Copper Alloy 505 (QQ-N-288, Comp. D) in the as-cast, annealed and annealed+aged [hardened] conditions.
NiDI Technical Paper 515 - SOME NICKEL-COPPER CASTING ALLOYS -- ENGINEERING PROPERTIES (1969)
"Presents chemical, physical and mechanical properties of nickel-copper casting alloys 410, 411, 505 and 506. Discusses their high strength and toughness and excellent resistance to corrosion by a variety of chemicals and marine environments. Includes information on heat treating, machining and joining."

I entered the following before bruv's post that Monel S = Alloy 505. The data agrees with that from above except for hardened condition elongation, which I've noted. Also, some yield strengths for this alloy are for 0.5% strain.
MONEL,S,[As-]CAST
Tension Ultimate .... 120-145 Ksi
Tension Yield Point .. 80-130 Ksi
Modulus of Elasticity .. 24.1 Million psi
Elongation % .......... 1-4 %

Thanks for the links kenvlach, I must have hit >50 sites during my search, but I missed these.

This doesn't sound right.
Just remember, these are low stength alloys.
They do look nice.

For seawater resistance, even titanium may be less expensive since probably much less weight needed.
What is your application?
