Ignition temperature for of steel is normally around 800degC.
It covers the steel, which is mostly iron, so that it is not exposed to oxygen in the air. Rust is iron oxide, a compound formed when iron reacts with oxygen in the atmosphere. If the steel is not exposed to oxygen, it will not rust.
Disclosed is a method for preventing hydrogen-induced disbanding of austenitic stainless steel cladding, which is made on a low alloy steel, in a reactor vessel which has been used in a high-temperature and high-pressure hydrogen atmosphere so the air must be excluded. The clad steel is cooled from its operating temperature to a temperature which is not lower than 100° C. Then, the clad steel is maintained at a temperature between said temperature which is not lower than 100° C. and a post weld heat treatment so as to effect hydrogen degassing treatment. Thereafter, the clad steel is further cooled.
Steel is not an element it is a metallic alloy containing iron, carbon and other additives. At standard temperature and pressure it is a solid.
Bare steel + moisture + oxygen = rust. Paint provides a barrier to shield the steel from moisture and oxygen.
You mean Is Steel, Water, Oxygen, and gold which one is a component well. The only that is a mixture is water.
Nitrogen displaces oxygen that originally came from Earth's atmosphere. In the absence of oxygen, steel can not rust.

Steel + Oxygen = Steel Oxide
There are various things that happen when oxygen combines with steel. The electrons are set free and this is what will cause rust which will make the entire structure weak.
Steel is more dense than oxygen.
It stops the steel from rusting by not letting oxygen or water touch the steel, as oxygen and water need to present for steel to rust.
That really depends on the temperature of the water and the steel !

Steel plow
At the temperature required for welding, austenitic stainless steel passivate so rapidly in the presence of atmospheric oxygen that a strong weld bond can not be formed.
Steel bars laid in concrete to reduce cracking do to temperature change
Oxygen is removed from iron ore to produce iron which is then refined and alloyed with other metals and constituents to form steel. The oxygen is removed from the iron ore by heating it to a high temperature in the presence of carbon (and other materials) as a reducing agent. Indeed, once iron is produced in this way some processes actually blow oxygen through the iron to burn away impurities. My point here is that most steel production does not involve removal of oxygen once iron has been smelted.
