Q:Does stainless steel watches rust?
Stainless steel doesn't usually rust..... However, a lot of so-called stainless steel watch cases are actually base-metal, and does.
Q:stainless steel refrigerator that doesn't leave fingerprints?
Stainless Look vs Stainless in refrigerators usually refers to true Stainless Steel versus Satina. There's pluses and minuses both ways actually. With true Stainless, you have the exact match to the rest of the kitchen (because Satina is only used on refrigeration), but it is more prone to fingerprints, and is not magnetic. The Satina finish has a good look when not directly near a Stainless appliance, and does not show fingerprints and will accept magnets, but is not an exact match to stainless. My usual recommendation is that if you have a kitchen full of Stainless products, stick with the true Stainless Steel. If the refrigerator is more isolated, or is the only thing you want to have a Stainless look, you may want to consider Satina. If you put a lot of magnets on the refrigerator, I'd also recommend to go Satina. And since you don't want fingerprints, the Satina steel might come to your liking.
Q:Does cold steel of kershaw make better knives?
Cold Steel uses an incredible quality of metal. If you want very durable go with that. The benefit to Kershaw is they make better folders. Fixed blade--go with Cold Steel. Folder, go with Kershaw. I get all my knives from the guys below, they have free shipping and really good prices.
Q:.308 steel cased ammo in my remington 7400?
Won't hurt anything, but do be aware, if you're plinking with it, that FMJ (and maybe even steel core), cheap ammo offers more chance of penetration and ricochet so be sure you've got a good back-stop so you know where those rounds wind up.
Q:Moravia’s coal and steel industries face challenges because they _____.?
As someone who have lived in northern Moravia at industrial steel and coal city of Ostrava, the closest point is b), but it is questionable. I am not sure how to compare efficiency of largest steel mill in Czech Republic in comparison to China which is the biggest exporter, but Czech steel factories were modernized and run more efficient that 25-35 years ago, and been privatized and owned by Mittal. The workforce had been shrinking, so not exactly sure what that c is pointing to (aging of workforce, size of it, or quality). Northern Moravia is a part of larger coal basin that extend to Poland with large coal deposits. This was foundation for the steel industry in the 1800's together with large ore deposits that was mined in proximity of the Beskidy mountains less than 25 miles from Ostrava. The iron ore mines had been depleted for several decades, and since the late 70's when communists run the country, they were already importing Soviet iron ore. Coal mining within city of Ostrava cased to exist in the 1990's due environmental issues, and also cost. The mines were getting deeper and more costly to operate and there is no more mining within Ostrava. Couple mines are still in operation in Karvina county which is next to Ostrava. Currently the coal deposits south of the city were not opened due environmental issue which would mean destruction of third largest mountain range in the country. Therefore, my conclusion is is b, as the ore and coal resources been shrinking. The biggest challenge not mentioned here is of course competition from Russia, Ukraine, and China, which can produce steel much cheaper.
Q:Different properties and uses of three types of steel?
Steel is basically Iron with Carbon! The higher the % of Carbon, the stronger the steel, but the less tensile (Bendy) strength it will have!
Q:Will steel scratch titanium?
Will Titanium Scratch
Q:Can fire resistant building materials burn hot enough to melt steel columns?
Steel loses strength as it is heated and will fail long before it melts. A mild steel that starts out at 100 degs F with an allowable stress level of 20,000 psi will be down to only about 2000 psi at 1000 degrees. As to fireproofing for steel. It doesn't have an unlimited life. In fact most has only a 2 to 4 hour rating and that is determined in ideal conditions in a laboratory. The idea is to give firefighters time to get everyone out of the buidling.
Q:what are the characteristics of iron / steel?
Steel is harder and more brittle than iron since it has impurities which disrupt the regular layers of atoms. This means that the iron will stretch further and more easily. This also means it will stretch more easily.
Q:Are there steel bullets?
I personally know of no steel bullets. In order to be soft enough to engage the rifling in the barrel, it would have to have a jacket at least the thickness of the groove depth. Separate loading(those which a projectile is loaded followed with various sized powder charges) howitzer projectiles are cast steel with copper driving bands set in grooves to engage the rifling.
