Q:What is the highest quality carbon steel or cold steel a katana can be?
Types of steel are one issue. But the quality of steel no matter what type is even more important. The only way to be sure that you are getting a good blade is to buy from someone that already has a reputation for producing great blades. Stop the questions about who thinks what type of steel is best and investigate the steel blades offered by companies like Bugei Trading company. they have good blades. Opinions vary, but Bugei has proven that they make good swords. That is all that is needed to be known. Any questions you have are best directed to them, not here.
Q:Physics! Steel pots and pans?
Yep I agree with Scamper. Copper pot would be toxic so lined with tin or stainless steel.
Q:Question about building buildings with a steel frame.?
Most of the parts are cut, welded, and fabricated indoors in a welding shop at another location. Then they're trucked to the site and simply need to be bolted together. This is made possible through the use of computer aided design and modeling programs, so that parts can be made to fit almost presciently in the field. They buy the steel from steel companies. I couldn't tell you exactly where it comes from, you'd have to ask the contractors themselves.
Q:STAINLESS Steel....?
Stainless Steel is named that because when compared to untreated steel it is virtually stainless. It is virtually stainless, and harbors very little germs and bacteria. That is why it has been the standard in the food industry for years.
Q:Why does stainless steel get rusty?
You can rub the rust off with anything, from steel wool to Ajax. Although if you've previously used steel wool to clean it, that could be why it rusts. We had that problem manufacturing stainless steel railing and had to put it together on an aluminum table and polish welds with grinding wheels that never touched steel. What rusts are steel particles picked up on the stainless surface. Another possibility is that some stainless is more magnetic and usually also heat-treatable. It has just enough chrome in it to classify as stainless but can get minor surface rust. Not nearly as much as plain steel, though. Use a scouring powder like Zud or Barkeepers Friend and a cloth or sponge to polish if it's a sheetmetal surface rather than a bar grille, because these have oxalic acid and no bleach. They don't leave corrosive traces of chlorine behind. In fact, oxalic acid reduces rust to iron powder. Which is really neat if you need to clean a small rusty item--stir one of these powders into water, drop in the rusty piece and check it from time to time. Rinse off any abrasive powder, dry it well and oil it. When the rust is gone, it leaves a fine matte finish behind.
Q:Steel Strings or Nylons?
Steel because I bought a steel string guitar and that's what goes on it. Had I bought a classical guitar I would put nylon strings on it, but I don't particularly want to play classical guitar music, so I bought a steel string guitar. That's my story and I'm stickin' to it!
Q:Where to buy silicon steel?
Here okorder.com
Q:can I freeze steel?
If you put steel in the freezer, allow it to cool to 32 degrees and then put it in water a transfer of heat will occur and the water will cool off. How much and how quickly, I don't know. I believe the Mythbusters did experiments on something like this. If it were economical, we woud see steel ice cubes being sold instead of ice makers.
Q:What is 12 gage Cold Rolled Steel?
It's gauge.
Q:Graphite or Steel Shafts for irons for a begginer?
I agree with Matt C. I owned both steel shafted and graphite shafted irons (Callaway BB 06 Graphite and Taylor Made R7 Draw Steel). My club head speed is 75 to 80 mph. I switch to steel to graphite because i gain yards at least 15 to 20 yards more. My 9 iron (graphite) is a 150 club and my 7 iron in steel shafted. So my advice is to try both and see which one is best suited for you.
