Q:is batman in man of steel?
No Batman will be in the next superman film think it's scheduled for next year
Q:Movies- Conan: What is the riddle of steel?
Doom answers this question by explaining to Conan that the true strength of steel is in the hand that wields it – in other words, it is the resolve and commitment we bring to a task, not the quality or quantity of tools we use in performing it, that is the most important factor in determining success
Q:What is the Shear Modulus of Steel and Silver?
Shear Modulus Of Steel
Q:Carbon Steel or Stainless Steel? ?
Carbon steel will corrode much more easily than stainless steel, and stainless can be made stronger than carbon steel. Stainless steel is also usually heavier than carbon steel, which helps to control recoil when the gun is fired (recoil is not eliminated, only reduced). Stainless steel can also be polished to a mirror finish, so it doesn't have to be chrome-plated for that shine. Probably the biggest plus to using stainless over carbon steel, though, is the fact that it is far less prone to crystalization than carbon steel. When steel crystalizes, it becomes brittle, and can break at the worst possible times. Bad thing about stainless: It generally costs more. Aluminum is much lighter than any steel, size-for-size, and can be just as strong, if not stronger, than steel; I've worked with aluminum alloys that require special-made tooling. The difference, besides the weight issue, is that aluminum (even most alloys) will become softer when it is heated to a specific point -- which is why it is not used for the barrels of firearms using explosive powders as the propellent source. Because of the cost of the alloys which can withstand the heat generated in the barrel of a firearm, it is just less expensive to use a steel barrel. And for a fella that is so pro-gun, the previous answerer sure seems ignorant of 'em.
Q:Is stainless steel good for a butterfly knife?
This isn't really a question for this section, but I'm still happy to help out since I'm a big cutlery nerd as well. One thing to look out for when buying a knife is a lack of specifics on what steel is being used. High Carbon Stainless Steel doesn't tell you what the steel is, just what it MIGHT be. Chances are it's something along the lines of 420HC or 440A, both of which are softer steels. They aren't the worst steels around, but they are very quick to dull. You'd be better off looking at the Balisongs of Benchmade. They'll cost more, but you'll know that you're getting something made with quality materials and that won't break on you. And if it does break for some odd reason, Benchmade's warranty and customer service are both fantastic. Although if a more questionable knife is okay with you as long as the price isn't too high, then at least 420HC and 440A aren't too brittle and will take a decent edge even though they'll dull quickly. As for whether stainless steel is good for a knife or not, that depends on the type of stainless steel and what you're going to use the knife for. Many stainless steels are more brittle than a carbon steel, so high carbon stainless steels are a bit more likely to rust but a little tougher as well. In a butterfly knife, a steel like that is a good way to go, although the steels used by Benchmade, as I mentioned, are of a much better quality.
Q:steel industry?
Since2003, India has been the largest sponge iron producer in the world. In 2005, out of total global production of 56.05 mt of sponge iron, India produced around 11.1 mt (19.8%). In line with production target of 110 mt of steel (National Steel Policy) by FY20, many steel producers have announced their capacity expansion plans by signing MOUs with various state governments like Chattisgarh, Orissa and Jharkhand. The steel producers are expected to add around 8 mt of capacity by FY 08. CARE estimates that during 2006-09, demand for steel in the domestic market would grow at a CAGR of 8.4%. HR steel because of its widespread applicability is expected to grow at a CAGR of 17.5%. During this period, major demand drivers would be Consumer durables, Automobiles and Construction. Domestically, steel prices of flat products follow the international trend. Globally, steel prices are expected to firm up with continued growth in steel consumption. Further, the winds of consolidation have gathered pace with Arcelor-Mittal merger and latest acquisition of Corus by Tata Steel. The Indian steel industry has announced huge capacity expansions. With commissioning of these capacities demand-capacity ratio is expected to decline in FY 09 due to excess capacity. Will this lead to a drop in prices with commissioning of these capacities? With China and India becoming the focus of major global steel companies, will the consolidation of steel industry in these countries continue? For comprehensive analysis and CARE’s future outlook on the sector, please refer to the exhaustive report on the Indian Steel Industry by CARE Research.
Q:Bendable steel for crossbow bow.?
You are trying to use plain carbon steel which only can be bent a little bit if it is to return to its original shape. You have to use spring steel or high carbon steel that is intended to be bent a lot and still recover to its original shape. Most people making crossbows with metal bows get a piece of steel from a leaf spring of a vehicle and grind it to shape. A steel bow cross bow almost always needs a very strong trigger mechanism and a miniature wench to pull the steel bow string into position. You might be better off making the bow of wood.
Q:Does mild steel have a high carbon content?
Steel is defined as an alloy of iron and carbon (often supplemented by further materials) with a carbon content between 0.01 % and 2.06 %. 4% is in the realm of cast iron, which isn't quite as rigid as steel. Mild steel contains 0.16 - 0.29% carbon. You're off by more then a decimal.
Q:Why is the American steel industry failing?
Q:How can I tell the difference between different knife steels?
So what does all that mean in the real world of knives. 420 has very low carbon by blade standards, as such it is just junk steel. There are three grades of 440, A, B and C. The amount of carbon in A is about half of what C has. (carbon is what makes steel get hard). Iron is very much like a sponge in that it can absorb and hold different alloys. These alloys give the iron different attributes, and they can magnify each other. Like a sponge iron can only hold so much, for Chromium it is around 13%. At that point the steel becomes stainless. The drawback is a loss of strength. As a bladesmith my knives are generally 59 to 60 rch, 420 and 440 at its hardest is 59 but at that it is brittle so most makers draw it down to around 57. In my test a knife made of 420 couldn't make 5 slicing cuts through rope (most couldn't make one). 440 averaged between 5 and 10. Compared to the lowest grade of carbon steel I use (5160) which average between 25 to 30 on the same rope. I have tested many stainless blades and the rule always the same, the more chromium past 13% the weaker the blade and the less edge holding ability.
