Q:what happen if carbon steel is exposed to an oxygen?
Assuming the steel isn't actually melted, two things will happen. First, a layer of iron(ii) oxide, FeO will slowly develop on the surface, getting thicker over time. This layer is usually poorly bonded to the metal surface, it tends to flake off, exposing fresh metal. This is known as mill scale, it's also known as wustite which is the mineral term. Second, the surface of the steel will become decarburized, essentially becoming pure iron, not steel. The depth of the decarburized layer depends on the temperature, time, and the diffusivity of carbon in the steel at the given temp. This has some implications to engineering, in hot-rolling or forging of steel shapes for example. It's often the case that the stress and strain in a material is greatest at or near the surface. Therefore the weakened, decarburized layer at the surface may have a much greater detrimental effect on the steel's performance than might be expected. In a more specific example, die and tool steels depend on their carbon content for their strength and wear resistance, Therefore if such steels are heated in an oxidzing atmosphere, wear resistance is totally destroyed: The thin decarburized iron layer will be extremely soft and malleable.
Q:when was steel first made?
Even in very early iron, a small amount of steel was produced by carburization, where the iron picks up carbon by laying in hot coals before quenching. This produces a thin layer of steel on the surface of the iron. By about 300 BC Damascus steel was being produced by the crucible method on the Indian subcontinent, and the Romans used steel from Noricum. In the first century BC the Chinese were melting cast iron and wrought iron together to make steel.
Q:Handgun steel question...?
The chrome moly alloy used in blued steel guns is the strongest thing out there today. Stainless guns sacrifice a little in strength in exchange for their rust resistance. Every maker has their own special alloys for various parts as well as proprietary techniques for hardening and tempering depending on the use a part will be put to. Keep in mind that the harder you make steel the more brittle it becomes. Especially true in knife blades also. A custom knife blade could be made much harder than they are, but would shatter under hard use.
Q:how do we steel a bitches boyfriend?
Well i never had to steel a guy because if I have to go through all of that obviously hes not for me. Also, I never been that desperate. But if you can steel the boy your going to share him with your twin? thats not very... normal. Also if you can steel the guy, how long do you think hes going to stay with you before someone else takes him. Also you should read more so you can spell better because cute guys try to take advantage of dumb girls.
Q:Stainless steel can be used to do??
I also know that jawaysteel this company, they're really good
Q:Wolf steel cased .223 for mini 14???
Wolf's steel cased ammo isn't bad as practice/plinking ammo, especially for the price, as long as you give your weapons MULTIPLE, THOROUGH cleanings between uses, to be sure and remove ALL the gas fouling left by the Wolf components. HOWEVER.................. As Wolf steel cases are lacquer coated, DO NOT leave a round in a hot chamber, even during short pauses between stages of fire on the range, as the lacquer coating WILL melt, and cause the round to seize in the chamber, causing extraction and jamming problems, especially if the weapon is allowed to cool down with the round left in the chamber. Be extra diligent in removing this lacquer fouling when cleaning the weapon later. I have personally seen other shooters have the case rims ripped off spent cases in the chambers, causing a trip to the gunsmith to have the stuck case removed without damaging the weapon's chamber and actioin, at no minor expense.
Q:When was steel first used in buildings?
steel was first used in the 1800s in buildings.
Q:What is the level of dependability of 1055 carbon steel?
1055 Carbon Steel
Q:Reloading and shooting steel.?
It would actually cost you more to reload steel.
Q:will a stainless steel gun rust?
Q: will a stainless steel gun rust? A: Under certain conditions, it can rust. But stainless steel will last longer than blued steel will under such conditions. Also, some parts of a stainless steel revolver might not be stainless steel. The internal parts may be normal steel. Q: I just bought a used Taurus 85 stainless 38 spl revolver, it's about 25 years old but looks like new. This is my first stainless steel gun. I'm wondering if there's any special things I need to be aware of or cleaning methods? A: There are no special methods required. Stainless steel is fairly convenient easy to clean and maintain. Carbon-fouling can still build-up and metal discolorations may occur. These can be cleaned up with cleaning solvents and the use of a Scotch-brite cleaning pad or something similar. If it gets a scratch, the scratch can be polished away or left alone and the scratch can become a badge of honor or something. Q: I have a chrome bore AK, cleaning is always super easy, wondering of cleaning a SS revolver would be the same. A: Stainless steel is pretty tough on its own. Chrome-lining a stainless steel barrel wouldn't be considered cost effective in most circumstances. Cleaning the inside of a stainless steel barrel will be similar to cleaning a blued steel barrel that is not chrome-lined.
