Why does mild steel need coating?
If it is not coated, it is exposed to the air (or whatever) and will rust.
What can destroy steel?
corrosion, rust, salt water, bird droppings, human tears
Is AUS 8A steel stainless?
yes. its a high carbon low chromium blend. which means it still can rust adventually but is able to hold an edge better.
Is mild steel better than stainless steel?
Per the attached related link, the density (hence weight) of stainless is slightly more than the mild carbon steel. Using about 8.03/7.84 ratio of density, for the same volume of material the stainless will weigh 2.4 % more.
With which industry was Andrew Carnegie associated?
the steel industry --Bear
What advantage does fiberglass have over steel for a ship hull?
Fiberglass has a higher ratio of strength to weight than steel does, and it is also completely rust proof, unlike steel.
What is the ratio between the thickness of rust and steel loss?
I am also trying to find out the same information. While I can not find any scientifically based research - all the "answers" Ive found indicate between 2:1 & 6:1, and most likely 4:1. Alternate Answer: Refer to the Pilling-Bedworth ratio (http://en.wikipedia.org/wiki/Pilling-Bedworth_ratio). It provides a theortetical volume ratio between the metal oxide and the elementary cell of the corresponding base metal. For iron, the ratio is roughly 2:1 (oxide to metal), but varies according to the chemical nature of the oxide, available oxygen, etc. It is important to note that this is a theoretical ratio comparing relative volume and may not directly correspond with the ratio of measured thickness in actual practice because of the way the oxide (rust) product forms and layers resulting in varying density. Often, the physical thickness of the rust scale on carbon steel is reported to significantly exceed twice the loss in thickness of metal section. Many professionals in the corrosion industry cite an observed ratio of for carbon steel that is 4-10 times that of metal section thickness loss, particularly on heavy rust scaling in a chloride-laden marine environment. However, I am not aware of any published research or testing that supports this commonly accepted assertion. This variance in ratios between the relative volume and thickness are possibly the result of voids within the formation of thick rust scale films. In my experience, we have observed rust scaling on carbon steel in a marine environment that is typically 3-4 times the thickness of the corresponding section loss in the base metal. In summary, the answers could be different depending on whether the question concerns thickness of the corrosion product compared to metal section loss, or the relative volume between base metal lost and oxide formed. There is published data tha supports a 2:1 change in volume for iron. But, in terms of physical thickness of the measured rust scale compared to metal section loss, it appears the ratio could be greater.
