Q:what are the differences between chrome and stainless steel?
Chrome looks better, but it will eventually rust if it's exposed to enough moisture. Stainless steel will not rust. I would spend the extra money and get the stainless headers.
Q:is carbon steel a good matirial for a usable sword?
carbon steel will hold a good edge, but will corrode easily. The nicest blades I have seen are made from damascus steel (repeatedly folded over and over). It makes a blade which is good and flexible sideways, but more rigid in the cutting direction, and it holds an edge extremely well. It also looks awesome due to the grain effect from the folds, but is very expensive.
Q:Does steel contain nickel?
Yes. Different alloys contain differing amounts.
Q:Can jet fuel melt steel?
Jet fuel is kerosene in 6 grades and highly filtered. can it melt or weaken steel? No, it preserves it.
Q:Magnet will not stick to stainless steel?
That's interesting that it caused deflection in the compass. A lot of stainless steels may be SLIGHTLY magnetic, because they have small amounts of ferrite or alpha-iron in them. Ferrite is one of the crystal phases of steel. It has a body-centered cubic (BCC) structure and it's responsible for the magnetism of ordinary steels. Adding certain elements like nickel, manganese, or molybdenum, changes the crystal structure of the steel to a face-centered cubic (FCC) structure, which is NOT magnetic. This crystal phase is known as Austenite or gamma-iron. However most iron alloys contain some impurities that may cause the steel to be not completely transformed into the FCC austenite phase, small areas remain as ferrite.
Q:Stainless steel vs carbon steel for swords?
Modern Sword Steels: Stainless - Used in decorative swords and knives. Stainless steel blades longer than twelve inches are too brittle for full contact use. 1045 Carbon - Strong, but soft compared to higher carbon steels. Reasonably cheap and acceptable for full contact use. 1060 Carbon - Harder than 1045, but not brittle. Holds a keen edge and is very durable. Somewhat expensive, but great for full contact use. 1095 Carbon - Sacrifices the durability of lower carbon steels for better edge retention and increased hardness. Somewhat expensive, but tough enough for full contact use. 5160 Spring - Extremely tough and durable. Great for full contact use when properly heat treated. 9260 Spring - Amazingly resilient and durable, but not unbreakable. Excellent for full contact use. T10 Tool - Exceptionally hard and tougher than other steels with similar carbon content. Keeps a good edge without sacrificing durability. Can be expensive, but is still great for full contact use. L6 Bainite - Can be very expensive, but is the toughest steel on the market when properly heat treat. Excellent for full contact use, but requires additional maintenance to prevent rust and corrosion. About Damascus Steel: Historical Damascus blades were made from wootz, an Indian steel with unique properties. The technique for making this type of steel has been lost, but there have been many attempts to recreate it. The patterns found on Damascus steel blades are a direct result of the sword-making process and are not entirely dependent on the type of steel used. Damascus swords were the finest blades of their time.
Q:Why can hot rolled coils be placed outside?
Because the stress of participation should be eliminated
Q:Do steel cartridge cases take less pressure than brass cases?
The ammo loaded in steel casing has a tendency to be loaded at lower pressures, for some reason. Most if not all of the steel case is of foreign manufacture. No reason steel can't be loaded to same pressures to that of brass, would probably seal better. Most of the calibers you describe in steel cases go in weapons with loose tolerances, like the AK. Lot of times, the steel won't seal in the chamber, creating blow by, putting crud in the chamber. This condition makes it hard to feed, chamber, and extract in a tight dimension chamber that is present in NATO weapons. AK's, due to more generous tolerances, won't be sensitive to this.. Weapons from NATO are of more tightly toleranced chambers like the AR, HK, Barret, etc. where brass is more reliable in sealing, and minimizes the blow by and keeps things clean, or at least more clean than a steel case that may not seal.
Q:Can you WELD STEEL to ALUMINUM? How much heavier/stronger is STEEL?
Yes you can, but you really dont want to. Aluminum conducts heat better than steel so the weld would not cool evenly and would be brittle. You would be better off using a bracket or bolt straight on.
Q:how simple is it to recycle steel?
You okorder.com/... mini-mills operate between 150,000-2million tons of steel per year. If that is the size you were thinking about... you are in business. But since you are asking on Yahoo Answers where no serious industrialist would EVER ask a question like this, I can only assume that your ideas of small are completely incompatible with reality.
