Q:Steel Pokemon?
Fire, Ground, and Fighting. 2 of the most common moves in the game now (Close Combat and Earthquake) will completely bone steel types.
Q:Better Movie: Man of Steel or Captain America; The First Avenger?
Pretty hard, I feel like Captain America The First Avenger had less flaws, but I more enjoyed Man Of Steel. I don't know why people didn't like how Cap first started out with advertising/singing and all that. I actually applauded Marvel for having the guts to stay true to the character's origin. Henry Cavill has the best look for Superman in my opinion, but I do agree with the critics that say he doesn't reflect the character's personality accurately. He's too dark, reminds me of Batman, but if he talked less. I disagree with the Superman killing conflict. True, the character is not a killer, but that's exactly why they wrote that in. Internal character conflict. Put him at war with himself. Plus, it gave the grand opportunity to give Doomsday his new origin, which I kinda liked. In the end, I'll say Man Of Steel, they really dove deep into that movie, it was well written and had a great plot. I loved seeing and learning more of Krypton. Crazy how I'm not even a huge Superman fan����
Q:Can you put steel strings on a nylon-string guitar?
Don't EVER put steel strings on a nylon stringed guitar. Steel strings have many times more tension than nylon strings. The bodies on nylon stringed guitars are braced lighter than their steel stringed cousins. If you put steel strings on a guitar designed for nylon, they will belly the top up as well as warp the neck. Since they're attached differently, you'd (luckily) have a hard time even getting steel strings to fit. Enjoy your nylon string guitar for what it is, and if you want to play steel strings, buy a guitar designed for them.
Q:Sandpaper versus Steel wool?
150 grit is standard for final sanding for poly. You could use 220 if you finish with something thinner like lacquer of if that's all you have. Even finer would work but not do much sanding.
Q:How does water cooling affect the hardness of steel?
When steel is slowly cooled, lots of carbon diffusion takes place because it is not very soluble in steel at room temperature. The carbon is in solution at high temperatures, and is rejected out of the lattice as it cools. And when this happens, the microstructure will consist of ferrite and pearlite, and the lattice structure will be base centered cubic (bcc). If it is cooled fast enough, then the carbon gets trapped in the interstitial sites of the lattice and distorts it to a body centered tetragonal (same as bcc, but elongated in one direction) This elongation strains the lattice and makes it harder. Also, when cooled fast enough the atoms do not have time to diffuse like they normally would and they shear into place. This forms the hard phase of martensite that is desired of heat treated steel. But then it must be tempered back some because it is too brittle.
Q:How can i make difference between iron and steel?
Iron is a chemical element with the symbol Fe, that has no engineering application as it is very soft. You are not likely to come across a piece of metal of pure Iron. Steel is an alloy of Iron that is widely used with different types for various application. The type depends on the alloying elements. An old and rough way of identifying them is to use a chart, that shows the spark pattern when they are subjected to grinding.
Q:Is mild steel environmentally friendly?
Steel just rusts, it doesn't produce any emissions just sitting there. They even make architectural steel called Corten to rust to a nice patina. If you consider how the steel was made in the first place, a great big NO! Steel making requires massive amounts of electricity plus it gives off some nasty fumes in the liquid state. Leather itself doesn't emit much of anything, but the dyes might. Again though, if you look at how it's made, tanning leather is right up there with steel mills and paper mills for pollution, some of the worst.
Q:how can you temper steel?
You can't temper all steels. Generally the material must be a high-carbon or tool steel. Different alloys temper differently, and tempering is usually done to get a specific set of characteristics, so you must know what you are working with and use the right methods and temperature. If you do it wrong, the material may be hard but too brittle for the purpose or have other issues. It can be simple, such as heating to a dull red, carbonizing the surface (use an acetylene rich flame until it blackens the surface) and oil quenching. Do that to a piece of tool steel (like a screwdriver) and it will case (surface) harden it to the point you can't scratch it with a file. Tempering changes the way the molecular structure in the metal is linked and oriented.
Q:Any idea why some gun ranges don't allow steel bullets?
Indoor ranges and ranges that provide steel targets don't like them because of the additional wear and tear on their equipment. Some outdoor ranges don't allow them because they can strike sparks when they hit rocks and cause a fire. Others don't care. Best to call ahead or check the range's web site, if any, to see what they allow and don't allow.
