Alloy Densities
Alloy Densities
(OP)
Hello folks, Happy Friday!
Does anyone know where to find densities of various steel alloys? Carbon and some flavors of stainless are pretty easy to come by but I'd like to know how the density various with the different Incos, chromes, etc. MY immediate question today is SA387 11 12 but I've had the question in general for a while now. Thanks!

I recall a recent NASA program I did some work on where the material density used in any analysis or model had to match the value given on a material properties list provided by the program office to 3 decimal places. Using 0.3lb/cu in rather than the listed value of 0.297lb/cu in was not acceptable. It seemed a bit extreme, but that's what the customer demanded so that's what we used.

@tbuekna, I work with cranes planning our company's heavy lifts and even with these fairly large-scale objects, I need to parse the difference between materials to a few decimal places. a stainless lining on a carbon steel vessel for example, or the difference between a carbon steel vessel getting replaced with a 1.5Cr.
Cheers y'all.

Speaking of which, depending on your application, that thickness tolerance may be significant. For example, if I remember right, the allowable mill tolerance on a 0.25" plate is about 0.04" over and 0.01" under, so weight could vary +16%/-4%, in which case, carrying density to 3 decimal places doesn't accomplish a whole lot.
Paint could add another 2% or so on a plate of that thickness.
Don't forget the buoyant effects of air and variations in gravitational attraction!

calculating weight to three decimal places is quite pointless.
if you need a highly accurate weight, you're better off weighing the individual parts. i'd be surprised if the difference from 0.3 lbs/ft3 is significant.
