20% Ni cast iron
20% Ni cast iron
(OP)
I have a partial info from a customer who makes aero space parts. He has asked for a casting containing 20% Ni,2% Mo and 3% C. I do not have complete details . I shall be thankful if I could have any more info on this alloy.

That is as close as I can get off of the top of my head.

Type D-2C has the following listed chemical composition;
C max 2.90%
Si 1-3%
Mn 1.8-2.4%
P max 0.08%
Ni 21-24%
Cr max 0.5%*
* - not intentionally added
It is known that Mo can be added to increase elevated temperature properties, which may be the reason for this addition.
Stated Mechanicals for D-2C
UTS min 58 Ksi
YS min 28 Ksi
Elongation (2" gage) 20%
Brinell Hardness (3000 kg) 121-171

I forgot about 2C, I never cast it. I did cast a lot of Type 5 with Mo sub for Cr for improved corrosion resistance.
