Q:carbon steel strength?
Ricki is correct. There is no way to tell how much carbon is present just from the term carbon steel. It comes in a wide range of grades within the general classifications of low, medium, and high carbon steel. What you'll get depends on the quality of the knife. As the carbon content increases, the steel becomes harder, stronger, and more responsive to heat treatment. It also becomes more brittle, so a **very** high carbon steel would not be the best thing for a machete. As Ricki said, plain carbon steels are not rust resistant. However, I have had a carbon steel machete for over 40 years and it's just fine. If you take care of it, it will last.
Q:advantages and disadvantages of steel structure?
Disadvantages Of Steel
Q:Are steel doors insulated?
Steel doors are insulated,but will feel cold in the winter.Feel all around the door weather stripping area and the seal at the bottom of the door to see if air is getting in.
Q:Are steel strings bad/hard for a beginner?
Steel strings are fine for a beginner. I learned to play on Steel strings and I have always preferred them to nylon strings.
Q:Divide elements of an alloy (Stainless Steel)?
Yes it is possible to recover individual elements from an alloy such as stainless steel, but not easy. Look up etching of stainless steel on google. This same etching solution will completely dissolve stainless steel. These solutions are strong acids such as H2SO4 and HNO3 so safety goggles and good ventilation are absolutely required. Once the metal has been dissolved, then you would need to use a qualitative analysis scheme to precipitate out the different metals one at a time as compounds, then do additional reactions to recover the metallic elements.
Q:Reloading and shooting steel.?
Definitely DO NOT reload steel cases. As far as shooting steel vs brass. Brass will always be better than steel in your gun. Steel is a harder and stronger metal and will wear the firearm quicker than brass.
Q:Is Steel crystalline in its makeup?
Steel is crystalline. In general the bigger the crystals the better.
Q:how to clean old steel coins?
if you collect coins, you need to learn that they must never be cleaned. cleaning, while it might make them look pretty, ruins their value as a collectable. ask your coin dealer.
Q:How to clean all-clad stainless steel pans?
I bought a badly scratched-up 11 inch All-Clad Frying pan off Ebay for $23.00. I needed a large all-clad frying pan. I took it out to the garage and first cleaned it with an 8 wire brush on my bench-top polishing / grinding machine. Then I installed a 8 polishing wheel on the bench grinder. I used some polishing creme I use on car parts that I bought from Caswell s Plating. Auto polishing for your car will work too. The outside polished up like a mirror - as good as my new All-Clad pieces. Remember people. This is stainless steel. It s a tough, tough metal. You can work it like a piece of metal just as All-Clad did at the factory where they made it. It would take years to wear through the first stainless layer with a polishing wheel and mild auto polishing creme just as it would take a lot to wear through your cars paint. After-all; All you are doing is preparing an optical surface.
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.
