- Q:What are the carbon emissions of steel?
- Carbon okorder.com/... - Similar pages - Life-cycle energy and emissions of marine energy devices | Carbon ...Carbon dioxide emissions per unit mass of steel: 1.75 tCO2/tonne steel ; Total mass of steel in device: 665 tonnes ; Carbon dioxide emissions due to .
- Q:Can your sweat tarnish real silver & steel jewelry?
- steel shouldn't really tarnish, it rusts and moisture increases that. Silver tarnishes when exposed to air and sulfur. Moisture increases the process a bit, but it happens anyway. Sweat is not gross, it's a necessary function of your body, otherwise you would die. A lot of sports people wear jewelry and they sweat a lot. If you wear the jewelry all the time, that will prevent the tarnish a bit. If you take it off, clean it (water and dish washing liquid), dry it and put it in a zip lock back to keep it away from air and moisture. In the end, cleaning the jewelry is quick and easy so don't worry about it.
- Q:Does shooting steel case ammo in a AR-15 ruin/damage the gun?
- No. People who say that don't use steel cased ammo. It it said its harder on the extractor. I don't see how. Its dirtier because it doesn't expand like brass does but the steel casing is still softer than the steel of the gun. That is a mild steel which isn't as hard as what most people are thinking of.
- Q:why do you heat steel when hardening?
- Halps is off base a little. The reason heat is involved in hardening of steels depends, a little bit, on how you are doing the hardening. If you are hardening by work hardening, you do not have to heat it at all. If you are barbarizing (case hardening), the temperature is raised to increase the diffusion rate of carbon into the steel, higher C content - higher hardness. If you are Thur hardening, you have to heat the steel to the austenitizing temperature (so the structure transforms to FCC crystals with higher solubility for C) and then quench it (cool it rapidly enough to freeze the C atoms in the martensite crystal structure). If you slow cool, the steel could end up softer than it started. All of these processes involve atomic level things. If you want to understand them on the atomic level, you need to study physical metallurgy of steels. It is a subject onto itself and is really quite fascinating if you are interested.
- Q:STAINLESS Steel....?
- Stainless Steel is named that because when compared to untreated steel it is virtually stainless. It is virtually stainless, and harbors very little germs and bacteria. That is why it has been the standard in the food industry for years.
- Q:why does steel have a density range when other metals do not?
- Steel is not a pure element it is an alloy. Steel is primarily iron but it has many elements blended in that change it's density including carbon,silicon, nickel, chrome, etc. Aluminum and copper , magnesium and so forth can be the pure element or they can be alloys too. If they are alloys, then their densities vary also
- Q:are Train Tracks made of the Strongest Steel?
- consumer-friendly steel is used however the rails are tempered to cause them to stand up to the pounding they get from the practice wheels,the intense velocity trains utilized in Europe are made up of a greater variety of steel in accordance to organization who makes them in Germany ,i think of it replaced into Krupp's of Germany who cause them to
- Q:Stainless steel vs carbon steel for swords?
- The decorative swords you buy are actually blunt. my brother bought a set and they were blunt. Also some of the swords you buy in the shops like the previous person said are for decorative use only. A real Samurai sword cost a lot more than 30 dollars. The program I saw on TV was about these swords and they said that they cost about 1000 dollars or more for the real thing. 30 dollars is very cheap for a sword also the machete is a wider blade compared to the samurai which is why it's probably stronger.
- Q:Steel Arena ...........?
- Though okorder.com/.. You can also have a look!!
- Q:Copper pots....tin or stainless steel lined?
- Stainless is a fairly poor conductor but that is not why it has hot spots. That's because they tend to be thin. Cast Iron is also a poor conductor and has about the most even heat distribution. Many Copper bottom pots are just Copper plated for looks. In fact only the most expensive will have the heavy Copper bottom needed for even heat. Tin is a metal, an element. Stainless Steel is a mixture ( alloy ) of Iron and Chromium or Nickel or both. I do not know of any cookware that is Tin plated on the inside. I like Aluminium clad Stainless Steel. Good heavy bottom for even heat and Al. is a good conductor. A little more expensive are three layer bottoms. They have the Al. between Stainless so you get the looks and easy cleaning os SS with the heat distribution of Al.
