Scuba tanks are rated to hold a maximum pressure given in pounds per a square inch the higher the pressure the more compressed the air inside the tank is and the stronger or thicker the tank walls must be to safely contain the air.
Scuba tank sizes and pressures.
The 2640 psi low pressure steel tanks are preferred by nitrox and technical divers who expect to be blending their gases using the partial pressure method.

The information is believed to be accurate but is not guaranteed.
Steel scuba tanks are denser than aluminum tanks meaning you have to be less concerned with buoyancy issues especially at the end of a dive.
The most common service pressures seen in modern scuba tanks are 2640 psi 3000 psi 3300 psi 3442 psi and 3500 psi.
What size cylinder do i need.
A drawback of high pressure scuba cylinders is that they require more metal to maintain the higher amount of compressed air inside.
High pressure steel tanks will have a pressure range between 3300 psi to 3500 psi 227 240 bar.
Smaller than an aluminum tank of the same capacity a steel scuba tank is a more compact air supply solution a fact that becomes doubly important for twin tank setups.

A diving cylinder scuba tank or diving tank is a gas cylinder used to store and transport the high pressure breathing gas required by a scuba set it may also be used for surface supplied diving or as decompression gas or an emergency gas supply for surface supplied diving or scuba.

For a 6 cuft bottle this means at 3000 psi the tank contains 6 cuft of air.
Divers who engage in very deep or long dives may prefer tanks with a greater.
However scuba tanks are available in different materials and sizes for a variety of applications.
For example most aluminum tanks from the smallest 6 cuft pony bottle to an 80 cuft tank have a fill pressure of 3000 psi.
High pressure cylinders are a new trend.
While steel and aluminium scuba tanks come in a wide range of sizes see above the following are the most commonly used sizes.
The difference between pressure volume it should be noted that the pressure of a tank is not a measure of the size or volume of a tank.
