Q:What is the high Carbon steel used by gerber?
The carbon content of the knife is done during the smelting process.For instance a knife that has a high carbon content will keep an edge much longer than one with a lower content. It is tricky because too much will cause the knife to be brittle and break easily. Annealing is also part of the process of knife making.
Q:Steel Making Process?
From what I understand of it, US steel is better as the steel is more recycled than Canadian, so a lot of that oxygen / CO2 has already taken place compared to working from ore. The second reason US steel is environmentally ahead of Canadian is that US tends to use Electric Arc, while Canadian uses Basic Oxygen, Basic Oxygen uses more energy than electric arc, and I think it also uses more oxygen, but I would suspect that oxygen that it uses is 'waste oxygen' and not converted into Co2 because the Co2 process is limited by the carbon, and steel only has so much carbon.
Q:what is the densest type of steel alloy?
Technically, any metal that is not pure could be considered a steel alloy with the addition of iron. Density will vary depending on the percentage of each alloying element. In commonly available alloys, those with a high percentage of nickel will be the most dense. Nickel has a high molecular weight and readily alloys with most other metals. This class of materials is stainless steels, heat resistant super alloys such as inconel, hastalloy, etc. Tensile strength is not directly related to nickel content. Elements such as boron, manganese, molybdenum, and chromium have the most effect on tensile strength in steel alloys both as rolled and heat treated. Hope that answers your question.
Q:Coating on Steel Wool?
It will be very effective if you remove the oil by appling protective polymer spin coating to the edge, top and underside of the wafer, which makes those surfaces impervious to most chemical etchants. To learn more about the spin coating theory you may check out the following source.
Q:how to tell if its stainless steel?
Stainless steel uses chromium in its mixture to thwart the affects of corrosion. General steel, or carbon steel, is generally almost completely iron and is used for far greater applications than stainless steel. Stainless steel is used mostly in kitchen appliances, utensils, etc... The best thing I can come up with is to find a way to measure the chromium content of the steel you are looking at. If it's around 3% chromium, it's probably standard steel. If it's somewhere between 10-15% chromium it's probably stainless steel (or even 4% plus). I can't tell you a fast and quick way to test the steel because from my research, it appears there are as many grades and allows of steel as there are uses for steel! There is one test I've seen for home testing surgical steel which is a higher grade stainless steel, that is to put scotch tape on one section of material then soak it in water for a 24 hour period, then let it air dry for 24 hours. You remove the tape and lightly polish the exposed areas to see if there was any discoloration or pitting on the exposed area. This test is mainly for surgical steel jewelry, however stainless steel is supposed to resist rusting more than standard steel, hence it might work for other steel types as well. You may have to read some of the other links below to get some other ideas on how you can test steel to see if it is stainless.
Q:Steel tonnage?
Find the volume of steel and then multiply that by the density of the steel.
Q:Pipe screens: brass or stainless steel?

Q:Is Carbon Steel a Metallic Material?
Carbon and iron are both metallic.... so yes. You leave the iron laying in the forge - and it soaks up carbon atoms from the charcoal - so that as the steeling process goes on, the original iron becomes harder and harder.
Q:Stainless Steel lock?
It's hard to give you a quantitative answer. There are different grades of testing standards for padlocks. It comes under the ASTM F883. You need to be more specific. The link only gives a picture and no details about the lock. But in general, stainless steel locks are pretty darn strong. Also, you are under the wrong impression about steel vs iron. Iron is a component of steel. Pure iron is very ductile and is softer than steel. Cast iron, is very hard, but is also very brittle and has limited uses. In general, mild steel is realitively soft and ductile. But, there are many different alloys of steel and some have hardnesses and strengths higher than cast iron. Stainless steel is typically more ductile that mild steel because of the smaller amount of iron in the recipe. There are exceptions to that as well. The 400 series of stainless steels have higher amounts of iron and can be heat treated to hardnesses equaling the better steel alloys.
Q:Is carbon steel strong?
The term carbon steel by itself doesn't mean much. All steel has carbon in it. The definition of steel is iron that has been heated and had carbon dissolved into it and trapped on cooling into its atomic matrix. The amount of carbon in a particular piece of steel does have an effect on its properties. The more carbon it has, the harder it is, but also the more brittle it is. So you can have a high carbon steel blade which is very hard, and holds a great edge, but is likely to break. Or you can have a low carbon steel blade that is very tough and hard to break, but dulls easily. Your real, traditional samurai swords were made to have a core of low carbon steel, jacketed with an outer layer of high carbon steel. Thus they were very strong and hard to break, yet had an extremely hard, sharp edge. If that's what you have you can probably whack away to your hearts content. But you probably have some kind of homogenous steel reproduction type blade. What you can do depends on what steel was used.
