strong, malleable and dense
Sound travels fastest in dense solids(steel, diamond, etc.). Since the particles of dense solids are very close to each other, the transfer of sound energy from one particle to another is much easier.
From most dense at the core to least dense proceeding outward.
Steel is more dense than oxygen.
the most dense is steel and aluminium.

Water
A solid block of steel would be more dense than a boat made of steel. This is because even though the density of the material, steel, is constant, the form makes a difference to the overall density. The block of steel essentially contains nothing but steel, whereas the steel boat is "hollow" and contains air, as well as other construction materials such as wood.
When steel gets hot, it gets slightly larger due to thermal expansion. Since the mass stays the same, and density = mass/volume, it gets (very, very slightly) less dense. So cold steel is more dense than hot steel.
Can you be more specific? If you are referring to steel as an element representing dense solids, it can do everything from construction to absolute destruction.

Er, Does Steel (by itself) Float when placed in water? (for purposes of this discussion, lets omit masses of steel less than that required to break the water's surface tension, and formulations/constructions of steel purposefully designed to not break the surface tension, both of which are probably possible) No, ergo steel is more dense in its "usual" formulations & construction.
The ship has enough gas in it to keep it afloat.
