Alloy composition doesn't really change the stiffness or density of steel.

Alloy composition DOES affect ultimate strength, ease of cutting in the shop, how it's affected by brazing heat.
If that is the case, I'm curious as to how Kaisei 4130R and 8630R differ. The latter is a Nickel Chro Mo, while the prior is Chro Mo, but the manufacturer specifies that the wall thicknesses and butting are equivalent.

Simply a matter of ultimate strength, cutting, and response to brazing? Any experience with those differences for these two steels?
