Q:Carbon Steel strength grading?
Yes. Most high quality knives are made of carbon steel versus say stainless steel. High strength carbon steel holds an edge well and is strong.
I will also strongly agree with Joshua, and Birdgirl. Besides after the cost of such reinforcements, would cost as much, or more than the cost of buying a new one. Besides if the guitar is a decent quality, the alterations made would destroy any value it has, as well as not guaranteeing that the guitar will even be fully functional, or hold together over a period of time. It could easily cost two hundred dollars to have done, and at that price, you could buy a decent one, that is made for steel strings. Also fo4rget mounting steel strings on the one you have, unless you want to destroy it.
Q:What is meant by 440 Steel?
The number just indicates which class of steel alloy it belongs. Yours happens to be a 400 series and happens to have no Nickel in it (440 Steel) and a higher amount of carbon (Nickel is very common in steel) When I say alloy, I'm referring to the different chemical formulas and processing of steel which vary for different uses like industrial use, medical use or decorative use. Think of the different alloys like the types of soft drinks out there. Coke, Pepsi and Dr. Pepper. They all have very similar chemical formulas; yet differ with their secret ingredients which is apparent in the taste.
Q:What's the best dishwashing soap for stainless steel?
Stainless steel that has screws almost always rusts in the dishwasher. Also semi-complicated stainless steel utensils rust in the dishwasher...things like an egg whisker. This is true no matter what detergent you use. Dishwasher detergent almost always contains bleach. That causes stainless to rust if it has nooks and crannies. The solution? Hand wash them and let them air dry. The only stainless steel I run through the dishwasher is table flatware (knives, spoons, and forks.) You'll get a much longer life out of your utensils if you hand wash them and just let them air dry.
Q:what is the chemical composition of the steel material to be used for steel tube ferules?
I don't know your application, but here is some advice. Case hard provides a hard shell around soft steel, depending on the bake, the case is usually .002-.008 thick. (thousands of an inch) Heat treated steel or tool steel is hard all the way thru. Case hardening, provides toughness with flexibility, however, once it's compromised, the part is scrap. Hardend tool steel is extreemly hard throughout and the harder it is, the more brittle it becomes. The application of the part will help you to determine the material needed. For instance; Plastic injection molds are very hard so the hot plastic wont erode them over years of use. Punch Press dies aren't as hard but are tougher to withstand the shock. Machine bolts are case hardened so they can last, but soft enough to allow some stretching during tightening. Either way, the time in mfg will be about the same. Most tool steels today cut like cheese, but take time to be heat treated. Tool steel will cost a bit more than low carbon steel. Low carbon steel is as machinable, and cheaper, but, again, the baking period is as long or longer than tool steel. There are a lot of materials on the market today that maintain the durability of heatreated steel without having to go thru that process. 4140, ( or chrome/moly) comes to mind. There are also some 400 series stainless that work as well, and others. You need to determine strength, flexibility, ease of mfg, cost and repairability when considering which steel to use.
Q:difference between metal and steel?
well, steel is a type of metal. It's sort of like asking the difference between a bug and an ant, an ant is a bug, but not every bug is an ant. Likewise, steel is metal, but not all metal is steel. Gold is metal, Silver is metal, Iron is metal, Steel is metal.
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:Different properties and uses of three types of steel?
TYPES OF STEEL: CARBON STEEL ============= Steels containing 0.2% C to 1.5% C are known as carbon steel. They are of three types. Low Carbon Steel It contains 0.2% carbon. Uses: Sheets, wires, pipes. Mild Carbon Steel It contains 0.3% to 0.7% carbon. Uses: Rails, boilers, plates, axles, structures. High Carbon Steel It contains 0.7% to 1.5% carbon. Uses: Surgical instruments, razor blades, cutlery, spring. STAINLESS STEEL =============== It contains 14% to 18% chromium and 7% to 9% nickel. Uses: Car accessories, watch case, utensils, cutlery. ALLOY STEEL ============= There are three types of alloy steel. Mn-Steel It contains 10%-18% Mn. Uses: Rail tracks, armor plate, safe. Si-Steel It contains 1% to 5% Si. Uses: Permanent magnet. Ni-Steel It contains 2% to 4% Ni. Uses: Machine components, Gear, shaft, cable. :) Ref. www.google.co.in/search?q=wikiso...
Q:quinching steel... hardening?
boy what a though question ! let me explain. when you rapidly cool a steel from high temperatures(depending on steel type) with water or oil or other means , it is called quenching. it depends on the steel type to say if it is better to quench it with oil or water but basically in water you will have a harder steel rather than oil. for some steels if you do this you will ruin it's properties ! you can't totally tell what kind of steel do you have until you get it analyzed with Quantometer analyzer with a pocket knife it is more like an estimation and it can't be trust able generally if you can scratch the steel with your knife it means it is not a hard steel and it might not be expensive. I hope that helps but for more information i need to know more !
Q:1 inch thick steel target good for mosin?
it depends on the type of steel. If it's soft steel it may stop the round, but leave a craterthat can causeirregular ricochets. If it's hardened steel (AR500 for example), the bullet will just 'splash' and fragment into little bits. It's better to shoot thin steel so the round goes through than shoot thick soft steel thatforms a crater. No matter what type you're shooting, put it no closer than 100 yards for a full power jacketed round. Try to hang the plateso it is angledslightly towards the ground so anymajor ricochets are directed into the ground and not up or back towards you.
