Steel cylinders are more susceptible than aluminium to external corrosion, particularly in seawater, and may be <a href="/wiki/Galvanization" title="Galvanization">galvanized</a> or coated with corrosion barrier paints to resist corrosion damage. It is not difficult to monitor external corrosion, and repair the paint when damaged, and steel cylinders which are well maintained have a long service life, often longer than aluminium cylinders, as they are not susceptible to <a href="/wiki/Metal_fatigue" class="mw-redirect" title="Metal fatigue">fatigue</a> damage when filled within their safe working pressure limits. </p><p>Steel cylinders are manufactured with domed (convex) and dished (concave) bottoms. The dished profile allows them to stand upright on a horizontal surface, and is the standard shape for industrial cylinders. The cylinders used for emergency gas supply on diving bells are often this shape, and commonly have a water capacity of about 50 litres ("J"). Domed bottoms give a larger volume for the same cylinder mass, and are the standard for scuba cylinders up to 18 litres water capacity, though some concave bottomed cylinders have been marketed for scuba.
