- Q:im getting a sword tommoro and i need to figure out the pros and con of stainless steel and carbon steel sword?
- For display stainless is ok, no maintenance is required, for actual use carbon steel it the way to go, these blades will rust and need to be taken care of.
- Q:What's better: Steel or Alloy bike wheels?
- I am a major advocate for steel in bicycle construction, except when it comes to rims. If you are using cantilever or caliper brakes, steel rims are a major no-no, as any moisture greatly reduces your stopping power, practically rendering your brakes useless. Sure, bright chrome rims definitely look nice, but their useful application is extremely limited, and mainly consigned to accurate restorations of antique bikes. If you really want to use chrome steel rims on a bike, make sure you have either disc brakes, drum brakes, or a coaster brake. Aluminum rims have been in use for about 100 years now, and for good reason.
- 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:what is 440c stainless steel means?
- It is the alloy number given by the American Iron and Steel Institute, or AISI. This is the trade organization of the U.S. steel industry, one of the oldest such organizations. 440C is also known under the UNS system as S44004 440C is a high carbon, plain chromium stainless steel. Or more specifically: 18% Cr, ~1.1% C, ~1.0% Mo, Si, and Mn 440c is mostly used in cutlery, bearings, and valve parts; because it has the best strength and hardness after basic heat treatment of any stainless steel. Relatively poor properties in other areas make it less suitable for other types of items. for example 440c becomes very brittle in sub zero temperatures. 410 is similar to 440, but it is a cheaper milder steel with less chromium and carbon, so it is less brittle, more easily worked and machined, but lacks final strength and hardness. it is often used in cheap stainless fasteners and bushings.
- Q:Steel case ammo in an AK?
- Look at it this way, steel ammo is what about 20 cents per round if you buy it at a gun show by the box of 500. Brass ammo costs like 45 cents per round at my local Academy Sports Outdoors. Now, the life of an AK with military steel case ammo is 25,000 rounds.... lets assume you can get an extra 10,000 by using brass ammo. If you have saved all that money by buying steel cased ammunition, you could buy 3 replacement AK's with the money you saved by the time you wear one out. The AK was made to use steel cased ammunition. All Russian designed weaponry is designed for steel cased stuff, I have heard they actually function better with steel. Something to do with the hardness of the metal.
- Q:Why is steel a stiff material?
- Steel is NOT stiff. In fact it is worldly accepted metals (steel is a metal) are not rigid in mechanical terms, and rigid means stiff. Steel easy to shape, but is strong and therefore hard to break. Thermosetting polymers (hard plastic) which is stiff, is in fact easy to break (weak) and also hard to reshape without changing its state (solid to liquid). Whoever told you steel is stiff is wrong and possible meant steel is strong, or you misheard/misunderstood.
- Q:Pipe screens: brass or stainless steel?
- Stainless Steel Pipe Screens
- Q:STAINLESS Steel....?
- Stainless Steel is named that because when compared to untreated steel it is virtually stainless. It is virtually stainless, and harbors very little germs and bacteria. That is why it has been the standard in the food industry for years.
- Q:Is boron steel harder?
- There is really no simple answer to this question. Boron is usually used for a handful of reasons, but most center on high volume low cost production of durable hardened steel. Boron is a very cheap way to get very durable parts with very minimal alloying of expensive materials. It was born of necessity during WW2 and is currently in WIDE use in bulldozer undercarriage. Probably in place of what would otherwise be 4140. Boron steel is quite a bit more difficult to properly heat treat. Better suited to mass production facilities with tight controls, but when done properly provides material just as durable as higher alloys. Not a backyard endeavor such as ht/tempering carbon steel or tool steels without appropriate homework and treatment controls.
- Q:Cold steel katana?
- Save your money and by a wooden boken. Train with a well balanced wooden one. It is how the great Japanese master started their training. Steel swords are good for display. and perhaps if you become relay good and want to feel the heft and practice cutting straw men and bamboo stalks than invest some money in the real deal for a few hundred $$ at the least.
