Q:Physics! Steel pots and pans?
Stainless steel is less conductive than copper. However, steel will retain heat longer and thus be distributed more evenly. (hence the thick bottoms, but also for balance). Copper on tea kettles is ideal to bring water up to a boil rapidly but since your not really cooking food, temperature distribution or control doesn't really matter. Now if your cooking sensitive food, then it does matter. For example, the use of a double boiler is preferred for chocolates. Temperature and distribution is critical. As far as relatively inexpensive copper clad pots and pans such as Revereware? Well, I don't see a difference but perhaps they did some testing.
Q:where can I find the weight of steel?
Category Material Density Metal Steel, tool 7.715 Metal Wrought Iron 7.75 Metal Carbon Tool Steel 7.82 Metal Steel, cold-drawn 7.83 Metal Carbon Steel 7.84 Metal Steel, C1020, HR 7.85 Metal Pure Iron 7.86 Metal Soft Steel (0.06% C) 7.87 Metal Stainless Steel, 304 8.03 Metal Stainless 18Cr-8Ni 8.03 I looked up specific gravity mild steel. This might get you pointed in the right direction.
Q:Remington 870 wingmaster steel shot duck hunting?
Because of environmental concerns steel, bismuth and tungsten is replacing lead shot, for bird hunting. The problem with steel shot is the hardness, which can cause damage to the bore and choke in older shotguns. Unlike lead there is no give to steel and it can damage the bore especially if the choke is on full. Tungsten is also very hard, but it is often alloyed with other metals making it softer causing less damage in older models shotguns. Bismuth falls in between tungsten and steel, being the softer of the two by far.
Q:what are the differences between chrome and stainless steel?
Chrome is a very hard metal that is plated over regular steel. It often chips and cracks off, allowing rust to form underneath. Stainless steel is an alloy of steel and nickel (I think) - sometimes the pipe is solid stainless, more often it's a coating. It doesn't rust, but also doesn't look as shiny in the beginning (stainless always looks better after a little time 0 chrome plate never lasts.) It's also softer, meaning that it doesn't tend to flake off like chrome does. Chrome plating if mainly for looks - stainless steel is for the longevity of your new parts. Chrome also tends to hold the heat in - not always good, as it will discolour with intense heat (very common on exhaust pipes), and the greater expansion and contraction during its usual heating and cooling cycles tends to make it flake off more easily. Bottom line - are you more interested in performance and keeping the car running well, or are you interested in temporary, short-term looks? After all, there's a reason that pro race engines don't use chrome plating.
Q:How does Steel help us in society?
steel comes from iron. Iron is a natural resource and is abundent in nature. so being able to turn it into steel means it can be used for alllll sorts of things! from buildings, cars, piping and tubes, to washing machines, appliances and many other things. its used in our everyday life and is a great, strong material.
Q:How to restore rusted stainless steel?
Nope, stainless steel is actually coated steel that can be removed by acid or scrubbing too much. it would need to be re dipped to go back to normal. would cost a fortune however.
Q:How can i make difference between iron and steel?
There are literally hundreds and hundreds of different commercial steel alloys and a good number of iron alloys so... it depends. Technically, steel is any alloy that is mostly Fe with some amount of carbon. Even if you have access to the necessary lab equipment, CTE (coef of thermal expansion) and specific heat are not very straight forward tests. There are, of course, chemical analysis instruments for measuring C content in steels so, if you really need to know, you can spend money at commercial lab that does these tests. One quick test to judge C content... touch the metal to a grinding wheel, higher C content produces more sparks. To calibrate the way this looks, compare the sparks from a drill bit (usually 1090 steel so 0.9 wt% C) to a steel nail (low C steel). Unfortunately, the difference in sparking between steels with pretty low C content and a piece of iron will not be very dramatic. Of course, iron might mean Cast Iron and, again, there are a good number of commercial cast iron alloys and there are 4 basic types of cast iron alloys and they contain high amounts of C.
Q:Wolf ammo/steel case ammo question?
if you were going to shoot thousands upon thousands of steel cases in your rifle, it would cause more wear than brass cases do. but for the casual shooter, it won't be a significant factor. Corrosive ammo is another story (but not all steel cased ammo is corrosive, and any made after 1975 is not corrosive). shooting corrosive ammo in a bolt gun is simple to care for. When finished shooting, simply clean out the barrel, chamber and bolt face etc with hot soapy water, or military bore cleaner. This nuetralizes the corrosive chemicals. then dry it well, and then do your normal clean and lube with break free CLP or whatever other lube you prefer. But for a semi auto, gas operated firearm, the cleaning process takes hours, with having to tear it down and clean every part including gas tube etc. As for the ectractor, same answer as above, since an extractor slides in front of the rim as the cartridge is fed, it really does not add much more wear if it is steel. The firing pin does not contact the steel case, only the primer, so no additional wear there. The biggest problem with wolf ammo is encountered when you fire a lot of rounds quickly, building up a lot of heat, which can cause the lacquer sealent on the case to turn gummy and this in turn will cause problems for the firearm. Answer? first, use wolf ammo for casual shooting and clean the firearm extensively afterwords. Save your better ammo for real life situations. I understand that some of the newer wolf ammo does not use the same lacquer sealant. I believe it is called silver bear, but don't quote me becasue I can't swear that that is it. shoot safe
Q:Is steel industry good for investing currently ?
I feel metal stocks can give some return now if you invest.
Q:How to weld stainless steel?
There are many ways in welding stainless steel, such as coating manual welding,argon arc welding, pulsed argon arc welding, MIG, pulsed MIG, double pulsed MIG. Different welding ways own their merits and faults and adaptive working conditions. It is recommended to choose pulsed MIG, its molding very good and efficiency high, so it is mainstream application for stainless steel welding. Now many digital welding machines can supply these welding methods at the same time. And their welding effects is far better than traditional machines. Among them, FRONIUS’s TPS series and Nebula series are representitive products.
