Q:Stainless steel or Carbon steel knives?
I hate stainless steel! I hate shiny blades also! When I was a kid knifes were awesome! You could actually sharpen them! :) If we bought a new knife we would take an orange and slice it and leave the juice on the blade to purposefully darken it. If you had a shiny blade that looked like stainless you were not cool. :) I think most anyone who had an old knife from back in the 70's or before would agree that these new stainless knives are crap. I have not seen anything perform close to the old blades in stainless. Today I bought a case CV Sod Buster hoping it will perform like the old knives. What reading I have done the Chrome Vanadium is supposed to be like the old steel. I sure hope it is. Now to find some fruit to get rid of this annoying shiny blade! :)
Q:Can a fine grit whetstone replace a honing steel?
A steel is to clean off an edge and remove any bends on the bevel, it is not directly for sharpening as it removes no material from the knife (or should not). A whetstone, however fine, does remove material. A steel to maintain an edge, a stone to restore an edge. They are different items for different purposes.
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:Where can you get a thick sheet of steel?
Try the business-to-business yellow pages in your area. A local hardware store can also tell you who to contact. Or search steel plate or sheet metal on the internet to find a local supplier. No, sheet steel is not bullet proof, unless you get heavy plate. Depending on how thick it is, the plate will deform if hit by a high velocity bullet, but usually not enough to matter. Bullets have velocities from about 500 ft/sec up to roughly 3000 ft/sec, depending on the type of weapon used. I wouldn't try to use anything thinner than 3/4 inch. You'll have to experiment and see what it will actually stop. I can't guarantee it'll stop a high-velocity rifle slug. Try it and see.
Q:Disadvantages of stainless steel?
Stainless Steel has more advantages than disadvantages. But u asked for disadvantages so they r as follows i've given common disadvantages more can be found on Google. Disadvantages of Stainless Steel: Stainless steel tends to scratch and dent. Food, grease and fingerprints show very clearly on stainless steel, making frequent wiping and cleaning a necessity. High initial cost Difficult to fabricate, or in other words, it is not as malleable as other metals, say iron, and hence if not fabricated properly, results in costly re-work. Difficult to weld High cost of polishing etc. i.e. adding finishing touches for the market. there are advantages more than disadvantages. But u asked for disadvantages that's why i have given only disadvantages of stainless steel Hope what u want u got.

Q:Does mild steel rust?
Mild steel is an alloy. It is the most common form of steel. Mild steel (a so-called carbon steel) is a general term for a range of low carbon (a maximum of about 0.3%) steels that have good strength and can be bent, worked or can be welded into an endless variety of shapes for uses from vehicles (like cars and ships) to building materials. The carbon does not stop the material rusting or corroding. In addition to iron, carbon, and chromium, modern stainless steel may also contain other elements, such as nickel, niobium, molybdenum, and titanium. Nickel, molybdenum, niobium, and chromium enhance the corrosion resistance of stainless steel. It is the addition of a minimum of 12% chromium to the steel that makes it resist rust, or stain 'less' than other types of steel. The chromium in the steel combines with oxygen in the atmosphere to form a thin, invisible layer of chrome-containing oxide, called the passive film. The sizes of chromium atoms and their oxides are similar, so they pack neatly together on the surface of the metal, forming a stable layer only a few atoms thick. If the metal is cut or scratched and the passive film is disrupted, more oxide will quickly form and recover the exposed surface, protecting it from oxidative corrosion.
Q:Steel and Iron Ore?
Then people like Bull tell you the country is going down yet Lakshmi and Mark Mobius(read last week's FM) show confidence in SA. Sieman, IBM and CNBC are investing millions in the country. Now who do believe?
Q:Are Black Steel and Black Iron the same?
Black steel is steel with a surface layer of dark coloured iron oxides used for low pressure hot water heating pipes. Black iron is iron without any finish on it, which is really gray-black in color. they may be the same as many people often confuse iron and steel. Since the steel is simply steel with a covering, it could describe any steel including your silver steel.
Q:slingshot ammo: glass or steel?
Steel has more mass.
