Q:can you put nylon strings on a steel string acoustic guitar?

Q:Does stainless steel watches rust?
Stainless can oxidize over time but it doesn't look much like regular rust. Depending on the exact composition of the stainless alloy in question and what other materials are in contact with it, that's more or less of an issue. In constant contact with skin oils and gentle polishing from contact with skin and clothing, watches rarely rust regardless of what they're made of, I think you have nothing to worry about. Note: for future reference, bleach is absolute hell on stainless. It's bad enough on steel, worse on stainless. Especially because you have this idea that stainless is more or less impervious, when in reality it just isn't.
Q:steel or vinyl siding?
I'd like to know why you need to re-side it. I would get vinyl because it will not need painting as soon as steel.
Q:Sandpaper versus Steel wool?
Sand between coats with 220 to 280. 0000 and lemon oil is good for buffing final coat. That is if you don't want a high gloss finish.
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:What are surgical steel earrings ?
Surgical steel is a grade of steel often used in medical appliances like tweezers, forceps, etc. It's generally non-reactive and considered very safe. It doesn't contain any special properties against infection--you still have to observe basic hygiene and clean your piercings properly--but most people can wear surgical steel earrings without a problem. However, if you have a contact allergy to base metals like nickel, surgical steel may cause redness or irritation because of the metals used in it. If cheap rings or necklaces make your skin break out in a rash you should NOT wear surgical steel.
Q:What types of ammo can penetrate 1/2 inch steel plate ?
At what range and angle of impact? And is this mild steel plate or armor plate and if it is armor plate is it cemented, face-hardened or RHA? What Brinell hardness is it?

Q:Why are properties of steel not identical?
Grade 440C is one of the highest strength stainless steels. It is also very wear resistant. Good for use as ball bearings and other high wear applications. 400C has the highest carbon content of the 440 steels. 440A and 440B are identical but have lower carbon contents and have lower strengths and higher corrosion.
