Q:What is the Rockwell (HRC) Indentation Hardness of Steel?
Hrc Steel
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:i need help about stainless steel?
Weathering steel will rust, but the rust will be adherant and not flake off and be replaced by new rust. Therefore once it rusts it will pretty much stop rusting any more. One (severe) down side is that anything around it will be streaked with rust stains and it will look awful. Some bozo with the Texas Department of Transportation designed a number of freeway interchange overpasses here in Houston using Cor-Ten steel and all of the concrete supports are streaked with red rust stains and it looks like hell. Cameron built an office building here in Houston with a Cor-Ten facade and it is streaked with rust too. They should have gone ahead and spent the money and painted them, but they didn't.
Q:Do any of you teens out there know what a Steel Guitar is?
Well, my digital piano has a Steel Guitar setting that makes it kind of sound like one, but other than that I know nothing about them.
Q:how can one go about melting and casting steel?
Sand casting useing silica sand was the classical method. Wood models called patterns made the cavity into which the metal was poured. Furnaces capable of melting iron and steel are not found everywhere. They are industrial machinery, not to be improvised. Some-one had better be very careful if he does get access to molten steel. There are some aspects of the process that are not intuitively obvious that can 'bite you' badly. Get at least some briefing from an experienced foundryman.
Q:Superman man of steel?
Adamanium might be able to penatrate Superman's skin, but you would need a lot more force than Wolverine's arm could manage, perhaps an ultimate fastball special, fans know what I mean. It has never been determined what can penetrate Superman. Guess it depends on who's writing it.
Q:What is the level of dependability of 1055 carbon steel?

Q:What's the best material for color coated steel coil?
Galvanized steel sheet with hot-dip galvanized or zinc plated surface.
Q:How is steel manufactured?
The steel consists of ( Iron ) and another matter... but the popular one is iron+carbon / iron+silver - When iron is smelted from its ore by commercial processes, it contains more carbon than is desirable. To become steel, it must be melted and reprocessed to reduce the carbon to the correct amount, at which point other elements can be added. This liquid is then continuously cast into long slabs or cast into ingots. Approximately 96% of steel is continuously cast, while only 4% is produced as cast steel ingots. The ingots are then heated in a soaking pit and hot rolled into slabs, blooms, or billets. Slabs are hot or cold rolled into sheet metal or plates. Billets are hot or cold rolled into bars, rods, and wire. Blooms are hot or cold rolled into structural steel, such as I-beams and rails. In modern foundries these processes often occur in one assembly line, with ore coming in and finished steel coming out. Sometimes after a steel's final rolling it is heat treated for strength, however this is relatively rare.
