No. A hollow steel ball will not crush underwater. One reason this is true is because the steel ball cant go under the water in the first place because it hallow.
If a steel ship were not hollow, it would be much heavier and have a higher overall density. This would make it more difficult for the ship to float and it would likely sink. Hollow spaces in a ship contribute to buoyancy and help the vessel stay afloat by displacing water equal to its weight.
A steel boat floats on water because of its shape and displacement of water, which creates buoyancy. The boat's hollow structure allows it to displace enough water to counteract its weight, making it float. In contrast, a solid steel block is too dense and heavy to displace enough water to float.
For an object to flat it must displace more water than it weighs. So a 1 kg hollow steel ball bust displace 1kg of water. 1 kg of water has a volume of 1 litre so the steel ball must have a volume greater than 1l. Note: 1lite = 1000cm^3
A ship made of steel floats because it has a hollow structure that displaces enough water to create buoyant force greater than its weight. A needle sinks because its density is greater than that of water, so it does not displace enough water to generate enough buoyant force to support its weight.
The shape of the ship allows it to float. Imagine a ship that was just a big block of steel, If you put that steel block into water, it would sink because it is denser than water. Ships are built with a hollow shape. The amount of steel is the same, but the hollow shape decreases the boat's density. Water is denser than the hollow boat, so the boat floats. Shaping the block into a hollow form increases the volume occupied by the same mass, which results in a reduced overall density. The ship floats because it is less dense than water.
Hollow section steel rod rust when in contact with water.
it is hollow so it will float
Steel wool does not get softer under water. That is just your perception.
The needle is solid, it's density higher than water's. The ship is hollow, its overall density lower than water's.

they do not get crush because they are very strong and they can breath under water

Stainless steel with a hollow air core vacuum sealed is the best. Stanley is one of the best.
Stainless steel is not significantly soluble in water under normal conditions. However, prolonged exposure to certain corrosive environments, such as acidic or saline water, can lead to some degree of dissolution or corrosion of stainless steel.

A steel marble will sink because it's solid steel and heavier than water all the way through. A steel ship is hollow and the inside is full of air. Just the shell is heavier than water but, on the whole with the air inside, the ship is lighter than the water so it floats. Experiment: Take an old, empty can (with no lid on it) from the kitchen and submerge it water. It will stay submerged. The can itself is heavier than water. Now fish the can out and empty the water out of it, and put a small weight (maybe a small piece of stone or something) to hold the can upright in the water. The can will now float!
