Q:How much lighter is aluminum than steel?
A steel frame would weigh at most 2 pounds more than an aluminum frame. That would be comparing a less expensive steel frame to a really good aluminum frame. However if you are talking about comparable prices the weight difference would be much less, about 1 pound
Q:Can I load my own steel core ammo?
Please You're likely to find steel core ammunition from any of those manufacturers, and many more. Have fun... but steel core ammo is no more effective than lead ammunition, unless you're planning a crime spree and want to attempt to punch through a ballistic vest, and even that's not guaranteed.
Q:Why was molton steel found at ground zero?
Aircraft frames are made out of aluminum and magnesium which burn very hot once they reach flame point. The other 1000 degrees can come from fire being in a a semi confined space, and heat building over time, plus you can reduce the heat if you add pressure which the building was under to start with. I did like a 2 year stint testing construction materials, I know a little bit about how they behave.
Q:What is the structural formula for steel?
There is none. There is no steel molecule, so one can't draw its molecular structure. Most steel has a body-centered cubic (ferrite) crystal structure (some stainless steels are face-centered cubic - austenite). Depending on the alloying elements, it's typically a random solid solution. Most of the lattice sites will be occupied by iron atoms, but other atoms from the alloying components will replace random sites. Smaller atoms like carbon are in the interstitial points, meaning they fit in between the larger atoms. Depending on the alloy and the processing conditions, you can also get a mix of phases, including more complex structures like cementite (iron carbide), molybdenum carbide, manganese sulfide, or martensite (a non-equilibrium tetragonal phase).
Q:Cold steel katana?
Cold Steel makes the best and strongest swords around, ever cut through a steel car hood? Their swords can, I would suggest that if you but one, to also get yourself some life insurance... these things are incredible.
Q:What is the accuracy of steel tape inspection
This is the smallest scale brothers precision measuring tools, minimum scale steel tape is mm, mm is estimated to read out the data, such as steel tape measure length is 12.5 mm, which is 12 in the steel tape on the scale with the number of 0.5.It was read out. So the accuracy is millimeters.
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.
Q:what steel anodizes well?
Steel doesn't anodize in the sense that aluminum and some other metals do. However, it can be heat-colored. The trick is to clean the surface first (it must be oxide free), then heat gently until the colors appear. These are called temper colors in steel. They are due to a thin adherent layer of oxide that forms and thickens as temperature is increased. They are quite temperature dependent. As the steel is heated, the first color to appear is pale yellow. This will progress through darker yellows, browns, purples, and blues as the temperature rises. Above blue, the oxide becomes the gray/black color you are apparently getting - this is the result of heating too fast and too hot. See the chart at the site below for colors in plain carbon steel. Note that the temperatures are pretty low - It all starts around 400 F and if you go above 600 F the show's all over.
Q:quinching steel... hardening?
boy what a though question ! let me explain. when you rapidly cool a steel from high temperatures(depending on steel type) with water or oil or other means , it is called quenching. it depends on the steel type to say if it is better to quench it with oil or water but basically in water you will have a harder steel rather than oil. for some steels if you do this you will ruin it's properties ! you can't totally tell what kind of steel do you have until you get it analyzed with Quantometer analyzer with a pocket knife it is more like an estimation and it can't be trust able generally if you can scratch the steel with your knife it means it is not a hard steel and it might not be expensive. I hope that helps but for more information i need to know more !
Q:When was steel first used in buildings?
steel was first used in the 1800s in buildings.
