Q:Stain on stainless steel sink...?
in your super market their is a pad that is green and is called scooth bright use it on the stain and it will remve it
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:Are steel toed hiking boots worth buying?

Q:What is mild steel and what items are made from it?
not really. Coins aren't usually made from steel (e.g. an US cent is mainly zinc which will melt with releasing toxic fumes while welding), spoons are usually stainless steel (which is not mild steel), bottle caps can be steel but also aluminum. Fasteners can be made from a wide variety of metals. Generally mild steel is steel with a relatively low content of carbon (2%) which makes it easier to weld. It's used a lot for structure in building (e.g. rebar). Mild steel is also cheaper than other kinds of steel. Tools are usually made from high carbon steel. Generally I'd recommend to go to the scrap yard and pick up some shapes and pieces you like if you don't mind having to clean the rust off. Most will be mild steel. Welding small and thin pieces is much more challenging than welding larger pieces of metal. You are more likely to melt a bottle cap than weld it. Also your steel needs to be clean (no paint, sandblast or brush rust off). I would highly recommend to talk your project over with your teacher before you get all frustrated.
Q:what steel anodizes well?
Steel doesn't anodize in the sense that aluminum and some other metals do. However, it can be heat-colored. The trick is to clean the surface first (it must be oxide free), then heat gently until the colors appear. These are called temper colors in steel. They are due to a thin adherent layer of oxide that forms and thickens as temperature is increased. They are quite temperature dependent. As the steel is heated, the first color to appear is pale yellow. This will progress through darker yellows, browns, purples, and blues as the temperature rises. Above blue, the oxide becomes the gray/black color you are apparently getting - this is the result of heating too fast and too hot. See the chart at the site below for colors in plain carbon steel. Note that the temperatures are pretty low - It all starts around 400 F and if you go above 600 F the show's all over.
Q:why would you clean metal with steel wood?
Steel wood? I don't think there is such a thing?
Q:How to weld aluminized steel?
Yes. Buy a bimetallic strip where one edge is aluminum and the other is steel. A bimetallic strip is a special metal strip where an aluminum strip is fused to a steel strip by high frequency welding. You can form the strip to the shape of the table legs' cross section then weld the steel edge to the leg and the aluminum edge to the table top. Ensure however that the aluminum table top is a weldable alloy and compatible with the bimetallic strip.( You can not weld Al. Alloy 6061T6 so look for Al.Alloy 5086H32 or 5456H321 or the lower Al. Alloy designations, but they have to be strain hardened and not thermally hardened).
Q:Aluminum vs Steel motorcycle gas tank?
Steel is most common. Aluminum is lighter but it's harder to form, so more expensive. Plus it dents more easily. And you can't use a magnetic tank bag. I've seen stainless steel tanks but they were usually specially made.
Q:where can I find the weight of steel?
Just know the type of steel ,its density. Density gives you weight per unit of volume. For example: The density of mild steel is approximately 7.85 g/cm^3 (0.284 lb/in^3) From above , you can say that 1 cm^3 of volume of mild steel have 7.85 gram weight.
Q:can you put nylon strings on a steel string acoustic guitar?
As others have said, it is not recommended because the steel-string neck is meant to handle the tension of steel strings, and nylon strings have much less tension. It won't do any immediate damage, especially if you loosen your truss rod a full turn or two to compensate. But if you keep the nylon strings on for too long your neck may twist or warp irreversibly. I don't recommend doing it, but if you want to try it anyway, get nylon strings with ball ends (Martin makes Darco strings with ball ends, and there are also Black Diamond strings with ball ends). Putting nylon strings on a steel-string guitar is not nearly as bad as putting steel strings on a nylon-string guitar -- whatever you do, don't do that!
