Submarines have to be very strong because when they are deep under water, there is a great deal of pressure exerted on them by the water. A hollow container underwater is not like a fish underwater, since the fish's body is filled with fluids (blood or other bodily fluids) that are no more compressible than the surrounding water is. Air behaves differently, it is compressible, so the hull must be strong.
Yes, steel is an alloy made out of mostly Iron and Nickel and if I'm not mistaken a steel crowbar is made out of steel.
High speed steel is made from different steel alloys. Depending on the application and budget the alloy is made from iron and different mixes of carbon, tungsten, cobalt, chromium, molybdenum, and vanadium.
Steel is an alloy because along with iron may contain many other alloying elements.
An alloy. Two types: substitutional (brass and bronze), or interstitial (steel).

your average steel is made of steel
Many many things can be made from alloy. Steel is an alloy. How many things can you think of made from steel?
Yes, steel is an alloy made out of mostly Iron and Nickel and if I'm not mistaken a steel crowbar is made out of steel.
High alloy steel contain: iron (base), carbon, nickel, vanadium, chromium, molybdenum, wolfram, silicon, etc.
Most submarines were made of steel.
Most hand drills are made of steel. Their drill bits are made of high sped steel.

A steel alloy
Spring steel is a low alloy, medium to high carbon steel that allows objects made of this steel to return to their original state. The density of spring steel is 7.85.
Most are made with stainless steel, or carbon steel. Some higher quality ones use a surgical steel or high strength alloy.
Steel or titanium
Spring steel is a low alloy, medium carbon steel or high carbon steel with a very high yield strength. This allows objects made of spring steel to return to their original shape despite significant bending or twisting.Applications include piano wire, spring clamps, antennas, and springs.
