Q:how does steel become stainless?
a little clarification. steel doesn't become stainless. There are many different types of steel, which is an alloy of iron and other element. The other elements determine things like hardness, corrosion resistance, etc. One element is chromium, which when added in the correct proportions, forms stainless steel. PS, there are many many different stainless steels, with different proportions.
Q:Cleaning granite and stainless steel?
The best home remedy for that is shaving cream. Use men's shaving cream, not the gel, and not the ones with aloe, but regular shaving cream. It'll get the crud off and it'll shine it up for you. Just make sure you wipe it down really well, so there aren't any streaks.
Q:has anyone heard about the 2010 specialized allez steel?
Steel? I doubt it's made out of steel, more labor and a heavier frame. Most likely aluminum. Shimano 2300 you say? The Shimano 2300 is the lowest of the low of Shimano road components. Most likely not too reliable and heavy. www.cyclestore.co.uk/productDetai... I think this is what you might be looking for.
Q:Will a stainless steel ring rust, or tarnish?
Stainless steel is a generic term for a huge variety of different alloys. In manufacturing, each steel has different numbers, etc that they go by. Some steel sold as being stainless actually is not. It rusts, like the cheap kitchen knives you see that are left in the sink too long. However, the stainless in jewelry is pretty legit. Overpriced, but legit. It will not tarnish, but it won't stay shiny forever. It might get a little less glossy over time. When it does get re-polished, it takes a long time to do it. But it will not turn black or rust. Good luck.
Q:Steel Cage Matches: Should they end by pinfall, escape or either?
That exists.. Ts called hell in a cell. And normal cage matches are fine the way they are
Q:is magnetic steel hygenic to produce stainless steel utensils?
Magnetic steel rusts. That's why kitchenware is often made out of stainless. You can't turn magnetic steel into stainless, sorry. Metalurgy is a complicated subject, and is all about different alloys. It's far too involved to explain in a few paragraphs here, but no, they're not interchangeable in this case unless you want to produce kitchenware that rusts.
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:223 steel cased ammo?
Steel cased ammo doesn't obturate (expand against the chamber walls) when fired as well as brass cased ammo does. This allows carbon to build on the chamber walls. Leading to failure to extract. But if you can get steel cased ammo for cheap, shoot it up! Just have a cleaning rod with when you shoot. If tapping the butt on the ground doesn't dislodge the spent case, push it out with the rod. Be sure to use a chamber brush when you clean your rifle after shooting steel cased ammo. I would never use steel cased ammo for defensive purposes in an AR however. The occasional failures to extract make it a bad idea. It's plinking ammo only.
Q:from where do steel plants in gary, pittsburgh, detroit and Birmingham get their raw materials?
A lot of iron ore is available in the upper great lakes region. Iron ore needs to be transported on large freighters, and the Great lakes served a purpose for that transit system as well. I cant say much about Birmingham, but as for Detroit and Pittsburgh, the steel forming industry has been greatly affected by the low cost Asian imports now available. I think what happened was this: The US used to subsidize the US steel industry, this kept prices artificially high ( compared to the world market ), but also kept the plants open. Sometime during the present Bush administration, the US stopped subsidizing the steel industry, and the Asian steel manufacturers started dumping steel here in the US at very low prices, this caused the US company's to stop or greatly lower their production, and many US steel plants went out of business. Now with the US steel companies out of the way, the Asian steel companies have steadily raised their prices on the US steel buyer. Hows that for fair trade, the steel industry isn't the only thing this has happened to either. I know this was a bit of a rant, but I wanted to point out how a once proud steel industry was put to death by politics.
Q:Which Material is Better? Glulam or Steel?
Steel is better. You can use a smaller size compared to wood, it will handle more weight and will not deflect like a lam beam can and will. I've worked in a lot of older houses and the ones with steel beams always had far less differential settling than those with wood beams.
