Q:Which is stronger for cars, carbon fiber or steel?
At a reasonably high speed, both cars would be undrivable. That's by design, not due to the strength/weakness of the materials. The energy in an impact needs to go somewhere. Cars are designed so the body and the frame will bend and break, reducing the impact on the occupants. If the car is too rigid the chances of the occupants being injured increases. Carbon fiber composites do have a better strength to weight ratio than steel but they're also a lot less dense, so the same volume of material will have a similar strength. The primary benefit to carbon fiber is that for a part of the same strength the carbon fiber part will weigh less than the steel part.
Q:Best hunting knife steel?
Regardless of who makes the knife, you might look at stainless steel instead of the better tool steels like O2,M2 or D2...stainless takes more abuse and neglect than the others do.
Q:Why not use stainless steel to make coins?
Stainless steel has been used by some countries to make coins, but it's not an ideal metal. When a coin is struck, a die comes down and strikes the blank with many tons of force (the blank is also sitting on top of another die--one has the image on the obverse (front) of the coin, while the other die has the image of the reverse of the coin). When the die strikes the blank, the force causes the metal in the blank to flow into the recesses of the die. The problem with stainless steel is that it doesn't want to flow into the die. To get an image, either the relief (how high the raised portion of the design will be) has to be very low, and the coin has to have a simple design, or they have to greatly increase the pressure of the strike. This slows the coining press down, and greatly shortens the life of the dies.
Q:Steel or Nylon strings for my guitar?
i have steel and i like the way it sounds but i like nylon better
Q:should i get steel shafted irons?
It depends on your swing speed. If you have a faster swing speed and notice you are consistently hitting high with your irons and having some trouble with accuracy, you will benefit from playing steel shafted irons. If your swing speed is on the slower end of the spectrum, stick with the graphite irons for a couple more years until you swing has developed and you are hitting farther.
Q:Mild Steel furniture finishing?
No, I don't think the oil will do what you want. I have heated and quenched metal in oil several times (to harden it) and it did not give a finish to steel. I have heard of heating steel to a high temperature (red) and putting powdered sulfur on it, it will make a black finish. BUT, sulfur stinks and you would not do this indoors. And I don't know what the results would be like for indoor use. At the hardware store, you can find something like POR (paint on rust), a brand name of rust neutralizer. There are others. You spray it on (or paint) and it will turn rust into a glossy black material. Other than that, I think paint is your best option. Check out the new finishes they have now, if you haven't checked, they have come a long way. If you let them dry completely (in the sun) the spray can finishes are very durable. Good luck! Ooops, I forgot about gun finishes. Yes, some are blue, you might be thinking of that, but that is only if you put several coats on. One coat might do it. Plus, there are other colors, such as black (see the parkerizing link on the list). Here is a good company, they can be lots of help, too.
Q:Steel question?
Strength of metals is normally measured by the tensile strength as the main measure although this is not the only property as hardness is another big factor. Basically, iron is soft and steel is hard. Plain iron is stretchy and does not corrode quickly, whereas steel is much stiffer and corrodes more quickly. The tensile strength of cold worked iron is about half that of an average steel, likewise the hardness is about half that of steel too. Pure iron, which is rarely used, is even weaker and softer again and a bit more like softer materials like copper and aluminium. Where confusion comes in is that there is another iron - Cast Iron - which is totally different to both iron and steel. Cast iron is very hard and tough but incredibly brittle so its properties are very different.
Q:where is steel obtained?
Steel is an alloy consisting mostly of iron, with a carbon content between 0.2% and 2.14% by weight (C:110–10Fe), depending on grade. Carbon is the most cost-effective alloying material for iron, but various other alloying elements are used such as manganese, chromium, vanadium, and tungsten. Carbon and other elements act as a hardening agent, preventing dislocations in the iron atom crystal lattice from sliding past one another. Varying the amount of alloying elements and form of their presence in the steel (solute elements, precipitated phase) controls qualities such as the hardness, ductility, and tensile strength of the resulting steel. Steel with increased carbon content can be made harder and stronger than iron, but is also more brittle.
Q:Question about steel studs.?
Ask a Carpenter friend where you can buy metal studs. There should be a large drywall supplier somewhere close to your area - they usually also stock metal studs and ceiling grid that sort of all goes together for contractors. You will have a choice of 20 or 25 gauge studs track. 25 gauge is pretty flimsy so I suggest using 20 gauge. Get a small box of tek screws to attach studs to track. Also get some self drilling drywall screws 1+5/8 for 5/8 thick gyp bd. or 1+1/4 for 1/2 gyp bd. I would also buy MR drywall (moisture resistant) for any work in a basement. Another tip : Buy some 1x4 composite trim boards to use for your bottom plate. Clean the slab good where you plates will go, then use some Liquid Nails hd and glue your plates down to the slab. That way you won't be drilling holes in the slab that could allow water to seep up through them. The composite trim will not wick moisture and it will keep your metal studs up off the floor should you ever have a water problem in the bathroom. Keep your drywall up off the floor about 1/2 by laying a scrap pc. of drywall against the plate before you hang the board. Allow enough room to line the perimeter of your door frame with 2x 4 vs. metal stud. It makes it easier installing the door and trim.
