Q:What is the difference between steel and iron?
Iron and Steel Manufacture, technology related to the production of iron and its alloys, particularly those containing a small percentage of carbon. The differences between the various types of iron and steel are sometimes confusing because of the nomenclature used. Steel in general is an alloy of iron and carbon, often with an admixture of other elements. Some alloys that are commercially called irons contain more carbon than commercial steels. Open-hearth iron and wrought iron contain only a few hundredths of 1 percent of carbon. Steels of various types contain from 0.04 percent to 2.25 percent of carbon. Cast iron, malleable cast iron, and pig iron contain amounts of carbon varying from 2 to 4 percent. A special form of malleable iron, containing virtually no carbon, is known as white-heart malleable iron. A special group of iron alloys, known as ferroalloys, is used in the manufacture of iron and steel alloys; they contain from 20 to 80 percent of an alloying element, such as manganese, silicon, or chromium.
Q:Consider an experiment in which an aluminum soft drink can and a steel soup can are left outside for a few da?
I'd expect appearance of reddish dots or stains of rust on steel, while aluminium should stay virtually unchanged. Explanation: Both materials oxidize in natural environment because of atmospheric moist, but in very different ways. As for steel, oxidation begins as reddish dots of rust which grow and become stains. Oxidation then progresses in depth causing decay of material, compromising its strength and structural integrity.
Q:Are the shafts on my clubs graphite or steel....?
Most steel shafts are stepped, meaning there will be a series of ridges that run down the lengeth of the shaft every few inches. Also, take a piece of metal and tap the shaft with it. If it makes a ping type of sound, its metal. If it makes a clunk sound, its graphite. Or, look out the window and ask the first person you see walking by. Unless they are younger that 10 years old, they should be able to tell you pretty easily.
Q:How to temper steel? ?
Heat treating easy, HA! It is the most critical part of bladesmithing. Done wrong and all those hours of work go up in smoke (or a snap of the steel). You'll need a bucket of oil, preferably one that is deep enough to go in point first. If not you'll have to go in edge first, not recommended on a double edged blade, ok for single edge. You'll need to build a charcoal fire long enough for the blade. You will need to blow air under the fire to get it hot enough, the challenge is getting the heat even. You get the fire going and established, put the blade in turning it back and forth (if you keep turning it in the same direction when it heats up you could work a twist in it). When it starts turning red pull it out and touch it with a magnet, if the magnet sticks put it back. Keep heating and repeating until the magnet no longer sticks. Heat a little more, then quench rapidly point first. Don't let the blade lean to one side as warpage will occur. When it cools enough to touch, check with a file. If the doesn't file cut then you've properly hardened the steel and it's ready for temper. Now comes the really hard part. Grind the scale off carefully,preferably with a side grinder with a flap wheel. I've had hard wheel break freshly hardened blades. After cleaning you'll need to put it in an oven (preferred) or use a torch and carefully heat the blade. Watch the temper colors (oven temp 500-550F) or with the torch as the steel turns colors blue to purple for a double edged weapon. Any warpage that occurs needs to be worked out at temping temp.
Q:Where do you find steel type Pokemon in pokemon diamond?
lucario is both fighting and steel if you got piplup, empoleon is water and steel, if you happen to have a shieldon (only in pearl) he is ground and steel. Bronzor and bronzong are both psychic and steel you can find them in wayward cave is the easiest place that is under cycling road Steelix is in victory road but i guess you aren't there yet hehehe.... aside from dialga, who is dragon and steel i think those are it, unless you have any others like heatran or magenezone sorry i can't help much Oh but I can trade a steeliz if you want? my name is JAY my fc is 1375.4387.9544 =D
Q:what metals are more dense than steel?
Look at a periodic table of the elements. The atomic weights are a guide to density. Tungsten is denser than tungsten carbide because it doesn't contain carbon. Also denser than steel are gold, lead, platinum, and a number of other metals. Steel is iron combined with lighter elements, so iron is denser than steel.
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: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:Why is steel a stiff material?
To say that steel can be bent and shaped fairly easily isn't quite true. It takes multiple tons of force to do so, requiring some very heavy machinery. I think you're confusing a couple of concepts. For example the idea of elastic modulus, versus rigidity Rigidity is the ability of a structure to resist a load. That depends not only on the elastic modulus, but on the size and design of the structure or object. You can build fairly rigid structures out of wood. For example roller coasters. Even though wood has a much lower elastic modulus than steel, meaning that it takes much less force to bend and deform a given sample of wood.
Q:Steel Case V.S. Brass Case ammo?
I think you answered the question correctly yourself. Yes. BRASS CASE IS BETTER. MUCH MUCH BETTER. Steel case is for the birds. Brass case feeds better in semi-autos as far as I can remember. High end guns all the way to cheapo's, the brass stuff is better. Ever notice how steel case cartridges almost always seem to have visible bulges in the cases right at the butt ends of the bullets? ? ? Not quite so with brass ammo. Cheap shots or expensive shots I prefer ammo in brass.
