Q:Is 30CrNiMo8 a kind of high alloy STEEL?
Pretty sure it's low alloy steel, it's harder to smelt as it can contain up to 50% of other elements.
Q:how to make a unique piece of steel?
If you're looking to make steel stronger, I can suggest 2 things: 1. If you're actually smithing the steel yourself, and forging it from hot liquid metal, then if you can get ahold of some Carbon (i have no idea where you can get some), you can add it to the molten steel to make it stronger. Sword Smiths did it all the time back in the Dark Ages. (you'll have to look up the exact Science and Process of how to do it) 2. There's a treatment for steel called Tempering. If you Temper the steel, it makes it stronger. You do this by 1st Forging what you're making. In this case, I'll use a sword. Take the Sword and re-heat it (i dont know the exact temperature) until it glows-hot. You can use a blast furnace, a campfire, or any other extreme-source of heat. Some companies use molten Salt - yes, the Condement, and dip the sword in it until it's glowing-hot. Now you have to super-cool it. This is simple, all you need is Ice water. Submerge the Sword in it, until it's cool to the touch. Now toss the Sword back into your source of extreme Heat. Get it glowing hot, and then take the sowrd out. Set it aside, and let it cool naturally. Once it's cooled, it's TEMPERED, and alot stronger. NOTE: If you stop at the ICE-WATER stage, you'll only succeed in making your Sword BRITTLE. You MUST Continue the Process once Started. - Hope this helps.
Q:Copper pots....tin or stainless steel lined?
Stainless is a fairly poor conductor but that is not why it has hot spots. That's because they tend to be thin. Cast Iron is also a poor conductor and has about the most even heat distribution. Many Copper bottom pots are just Copper plated for looks. In fact only the most expensive will have the heavy Copper bottom needed for even heat. Tin is a metal, an element. Stainless Steel is a mixture ( alloy ) of Iron and Chromium or Nickel or both. I do not know of any cookware that is Tin plated on the inside. I like Aluminium clad Stainless Steel. Good heavy bottom for even heat and Al. is a good conductor. A little more expensive are three layer bottoms. They have the Al. between Stainless so you get the looks and easy cleaning os SS with the heat distribution of Al.
Q:Wrestling Steel Cage?
the only thing you can find is a bird cage because their is no way you can buy a steel cage unless you build it yourself
Q:The strip tower height
Elimination measures: strictly control the shape of plate and reduce the serpentine; according to the different specifications of the strip, set up the take-up system; set the coiling tension of the strip.
Q:stainless steel properties??
Stainless steel is a generic term for a whole range (there are more than 60 types) of Fe-Cr alloys. They all contain some amount of C and some alloys include a good number of other alloying elements. In almost all cases, the materials have corrosion resistance due the Cr atoms that are in solid solution with the Fe matrix. Under corrosive conditions, the Cr forms a thin tight coherent layer of Cr-oxide. This Cr oxide coating prevents further corrosion so long as it is not chemically or physically removed. If the SS has been subject to mechanical abrasion, the corrosion resistance can sometimes be restored by a light exposure to nitric acid which passivates the surface, restoring the Cr-oxide layer. The carbon content is an important factor in corrosion preformance but so is the heat treatment. Under the wrong conditions and in different environments, all SSs can rust. One of the most common corrosion problems is sensitization which occurs in the heat affect zone (HAZ) around welds. If the C content is high enough and the heat is high enough, the Cr atoms in solid solution form Cr-carbides and are no longer available to form a protective Cr-oxide. The corrosion resistance can be restored by appropriate heat treatment.
Q:Why is steel a stiff material?
To say that steel can be bent and shaped fairly easily isn't quite true. It takes multiple tons of force to do so, requiring some very heavy machinery. I think you're confusing a couple of concepts. For example the idea of elastic modulus, versus rigidity Rigidity is the ability of a structure to resist a load. That depends not only on the elastic modulus, but on the size and design of the structure or object. You can build fairly rigid structures out of wood. For example roller coasters. Even though wood has a much lower elastic modulus than steel, meaning that it takes much less force to bend and deform a given sample of wood.
Q:Danielle steel..................................................................?
No they are a good read.
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:whats the average price of wide flange steel W10x30?
The price of steel is increasing daily, so an exact answer is rough. A W10x30 is a fairly common shape and shouldn't be too hard to find. For a very rough ballpark number, say $700/ton (installed price), the piece you require should be in the range of about $250.00 or less as I assume you'll be doing the installing. Please don't take this as the gospel, however. Price varies on location, stock, and availability. Open the phone book and contact your local steel supplier. Because the piece you require is fairly short, you might get lucky and find someone who has a waste piece that length that they will give you a good deal on. --------------------------------------... I just checked the AISC web site to verify the number I quoted above and they posted an article stating that the average mill price had just increased to over $1000/ton in May. The best advice I can provide at this point is to buy the W10 now and don't wait any longer.
