Q:Here is my dilemma, should I shoot steel case ammo in my ar15?
steel case does not cause additional wear to the gun's chamber when compared to brass case. many tests has been done and precise measurements taken, this myth has been proven false. lacquer coating can cause issues because it can melt and cool, and cause jams. this is easily remedied with a chamber brush and some solvent.. However, steel jacket causes problems. Steel is harder than copper, it does not deform as easily so it causes more wear to the barrel as compared to copper or brass. The rate is around 10-25%, inreasing if you hoot rapidly instead of slowly. more shooting = hotter barrel = faster wear. It's the same with copper/brass jackets, but steel jacketed always wears more than softer metals. TulAmmo (or tula) is particular is so cheaply made they don't have enough copper/brass wash on the bullet to survive firing, after a few inches of travel it's steel on steel contact in the bore and it can ruin a gun barrel very quickly. But... there is one exception. if your gun comes with a chrome-lined bore that is standard for most AR's , shoot all the cheap junk you can buy. chrome-lined steel is 2X as hard as plain steel. crappy tula .223 will not cause more harm to a chrome-lined bore more than brass or copper jacketed bullets.
Q:i want to see the atomic structure of carbon steel?
This is actually a quite complex question... The atomic arrangement in steels can be controlled over a pretty wide range of different structures. This is really the fundamental reason why steel is such a commonly used material. The different atomic structures produce different physical properties so metallurgists have developed many different processes to control the atomic structure to get the properties they want. One simple answer is that Fe is BCC, body centered cubic at room temperature at equilibrium conditions. When you heat Fe up, it transforms to FCC, face centered cubic. If you continue heating Fe, it goes back to BCC, then it melts. The addition of C makes these structures (and the transformation temperatures) different. Deviating from equilibrium conditions by, for example, cooling very quickly (quenching) creates different atomic structures (one of the most important is known as martensite). Depending on how much C is in the steel, you can also have two different atomic structures (two different phases) present in equilibirum, for example, pearlite which is a mix of alpha Fe (BCC) and iron carbide Fe3C (orthorombic crystal structure). So... you need to think a little more about exactly what you want a picture of. I hope this helps
Q:Bike Frame-Aluminum vs Steel?
Someone stated even the $99 walmart bikes are aluminum now. WRONG! Most Walmart bikes have steel frames unless you drop about $200.00. Personally, I prefer aluminum over steel. It's lighter, most times - just as strong and won't rust if you get a ding or scrape in the paint. See links below on Trek M/B. Trek 820 - steel frame - $329.99. Trek 3500 - aluminum frame - $359.99.
Q:The strip tower height
Causes: the strip has a larger snake shape; the take-up device holds the tension; the setting is unreasonable; the strip goes into the coiler; the centering is not good; the coil tension is not set properly.
Q:low density steel?
If a material has a lower density than steel, then it isn't steel.
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:Stainless Steel Pots and Pans?
I only cook acidic foods in stainless steel or tomato sauces, Marinara sauces. Or sauces with wine in it. Because stainless steel is good with those kind of foods. Maybe you should use a little more fat, butter or Olive oil. And don't get the pan too hot, ( I don't care what other ppl say). Sometimes I heat up the pan and put a pat of butter in the pan to judge how hot it is. Once the butter starts sizzling or sputtering, the pan has reached the right temperature. Don't let the butter burn, the pan is too hot if the butter scorches. You can put a tablespoon (or less) olive oil in the skillet first and then a pat of butter; let them blend together. The oil will help keep the butter from burning.
Q:which sounds better, nylon or steel string?
it all depends nylon is faster, and brighter than steel, but is available only on acoustic as coil pickups won't detect them(only peizo will). That is one reason. Another is price, you tend to replace the nylon more often as it is weaker, and less resistant to corrision. EVEN THOUGH strings have a larger price range, and be cheaper than steel, or considerably more expensive. overall the nylon is brighter, but quite-er. Steel is louder, but deeper. nylon doesn't get feedback as easily, and is amazingly fast and easy to play. some think nylon sounds old fashoined(it looks it too, with an open headstock, ond classical look(sometimes mistaken as another name for it). MY SUGGESTION- visit your local music shop and try out steel, and nylons to in person get a feel for the sound.(remember that you get what you pay for, go as high in price as you can reasonably afford) ALWAYS TRY BEFORE YOU BUY, PLAY BOTH TYPES IN THE SAME RANGE OF PRICE(at least $400), THEN DECIDE WHAT SOUNDS BETTER TO YOU(and of course feels better and easier to play).
Q:i have guestion a bout steel?
Steel is an alloy. An alloy is a mixture of metals melted together, a solid solution. There are many recipes for steel depending on what the use is. Steel is an alloy of iron and another metal .Low carbon steel has less than 0.3% carbon, carbon steel is 0.3 to 0.6% carbon Low carbon steels generally contain less than 0.25% carbon and cannot be strengthened by heat-treating (strengthening can only be accomplished through cold working). The low carbon material is relatively soft and weak, but has outstanding ductility and toughness. In addition, it is machineable, weld-able, and is relatively inexpensive to produce. Carbon steel, also called plain carbon steel, is steel where the main alloying constituent is carbon. The American Iron and Steel Institute (AISI) defines carbon steel as: Steel is considered to be carbon steel when no minimum content is specified or required for chromium, cobalt, columbium, molybdenum, nickel, titanium, tungsten, vanadium or zirconium, or any other element to be added to obtain a desired alloying effect; when the specified minimum for copper does not exceed 0.40 percent; or when the maximum content specified for any of the following elements does not exceed the percentages noted: manganese 1.65, silicon 0.60, copper 0.60.
Q:buying Stainless Steel refrigerator?
I'm looking too and certainly the designer trend is to buy stainless steel. They look classy, shiny and bring a darker wood kitchen more life. However, there are companies that have put out fingerprint/smudge free stainless models. I have found their surfaces don't retain fingerprints - do test them in the store.If you have small children, stainless isn't the best choice. I love the look and practicality of the French Door fridges - great for smaller spaces. I was all set to buy an LG fridge and now I'm hearing that they're going on fire? Be sure to check Consumer Reports before you buy. Many of the cheaper models are now made in Mexico. I do notice the quality difference when I'm opening and closing fridge doors in the showrooms.
