I don't know anything about the "modulus of elasticity" but I worked as a welder for quite a few years and I wouldn't say that SS and CS are equally in rigidity. SS is much more pliable and less likely to have stress fractures on welds when seeing extreme heat. SS also expands significantly more when exposed to extreme heat.
Also, if you have a stainless bar (say 316L for instance) and a CS bar of the same diameter, it will be much easier to bend the SS than the CS one.
