If i get a samurai sword made of carbon steel, what is the hardest thing i can hit before it breaks? Or will it not break?
The term carbon steel by itself doesn't mean much. All steel has carbon in it. The definition of steel is iron that has been heated and had carbon dissolved into it and trapped on cooling into its atomic matrix. The amount of carbon in a particular piece of steel does have an effect on its properties. The more carbon it has, the harder it is, but also the more brittle it is. So you can have a high carbon steel blade which is very hard, and holds a great edge, but is likely to break. Or you can have a low carbon steel blade that is very tough and hard to break, but dulls easily. Your real, traditional samurai swords were made to have a core of low carbon steel, jacketed with an outer layer of high carbon steel. Thus they were very strong and hard to break, yet had an extremely hard, sharp edge. If that's what you have you can probably whack away to your hearts content. But you probably have some kind of homogenous steel reproduction type blade. What you can do depends on what steel was used.
Real katanas need regular maintenance, they rust easily and dull quickly. If you get a replica chances are it will break the first time you hit anything with it. If you can find one, the WW2 officers swords were of good quality and the modern metals mean it doesn't rust or dull as easily. If you do insist on getting a carbon steal blade be ready to oil it often. It will rust at the mention of moisture.
If you can get it, and it is not in a museum or owned by a wealthy collector it is probably junk. a realsamuari ( warrior) sword probably took a year or more to make, 6 months or so to sharpen and was tempered by dipping in the blood of a peasant. It might have been marked by the number of human bodies it could cut through in one stroke ,1 was a minimum by all accounts they were the finest steel weapons ever made the curved thing in a knife shop is a cheap knock off
Carbon steel is an alloy that is made up of the mixture of carbon and iron. In addition, several other elements with low maximum percentages are also included, such as manganese, with 1.65% maximum, silicon,with 0.60% maximum, and copper, with 0.60% maximum. Carbon Steel Pipe Fittings are utilized in a wide variety of applications across multiple industries. They are typically used in large shipyards, fabrication companies, chemical plants, oil refineries, machinery manufacturers, textile, and fluid transportation companies among others. They are highly cost-efficient and are much preferred over other fittings.
