Q:I've been looking into battle-ready katanas a lot lately. And I've come across some debates between the best forges and steels to be used for them. The functional katanas I use now are Musashi brand katanas, using 1045 carbon steel. They each cost roughly $200-$250. The straight carbon steels are mentioned in the debates, but they aren't very sophisticated in their design. Now the higher end of this middle class of katana ($250-$1000) uses higher carbon. spring, damascus, and other various steels and combinations. I've heard a lot about the strength of damascus steel and it's cutting power. But I look for more than that. I've also been looking at (and for) durability, flexibility, and how well it stands up to contact. So I guess what I'm asking is for the opinion of people who have used these steels, and an answer on what the community thinks is the best steel for a mid range ($250-$1000) battle-ready katana. Looking forward to some good answers.

Q:Moravia’s coal and steel industries face challenges because they _____. a.do not run efficientlyb.have run out of resourcesc.have a declining work forced.have not privatized
As someone who have lived in northern Moravia at industrial steel and coal city of Ostrava, the closest point is b), but it is questionable. I am not sure how to compare efficiency of largest steel mill in Czech Republic in comparison to China which is the biggest exporter, but Czech steel factories were modernized and run more efficient that 25-35 years ago, and been privatized and owned by Mittal. The workforce had been shrinking, so not exactly sure what that c is pointing to (aging of workforce, size of it, or quality). Northern Moravia is a part of larger coal basin that extend to Poland with large coal deposits. This was foundation for the steel industry in the 1800's together with large ore deposits that was mined in proximity of the Beskidy mountains less than 25 miles from Ostrava. The iron ore mines had been depleted for several decades, and since the late 70's when communists run the country, they were already importing Soviet iron ore. Coal mining within city of Ostrava cased to exist in the 1990's due environmental issues, and also cost. The mines were getting deeper and more costly to operate and there is no more mining within Ostrava. Couple mines are still in operation in Karvina county which is next to Ostrava. Currently the coal deposits south of the city were not opened due environmental issue which would mean destruction of third largest mountain range in the country. Therefore, my conclusion is is b, as the ore and coal resources been shrinking. The biggest challenge not mentioned here is of course competition from Russia, Ukraine, and China, which can produce steel much cheaper.
Q:I need to identify a metal. It is rusty so I suspect it is either iron or steel. Since they both have similar densities and are magnetic, how do I tell the difference betweeen steel and iron?
Steel is a refined, alloyed metal that is mostly iron. Iron, in a chemistry sense os simply Fe. In an industrial sense iron is pig iron commonly saturated with carbon, up to 4.5% and has other impurities like sulfur. Pig iron is brittle and should break rather easily, and bend very little. After a piece is broken look at the crystal structure, you should see rather small crystals. Most steel made for car body's, washing machines, file cabinets, low grade bolts and nuts etc. should flex and bend before breaking. Most steel made for things like cutting tools, axles, etc, is hardened and will chip and break rather than bend. Also you can try to heat the piece to a glowing orange temperature. It must be very hot. Cool it. If there is a lot of white flake scale on the piece it is impure and probably iron of some sort. In the end the only way exactly tell is have an analysis done and look at the chemistry.
Q:I noticed a friend's appliances are not magnetic, and mine are. Both are stainless steel. Are there two types of stainless steel or something? Thanks
There are many types of stainless steel. Some are magnetic and some are non-magnetic. The magnetic properties of stainless steel are very dependent on the elements added into the alloy, and specifically the addition of nickel can change the structure from magnetic to non-magnetic. Poor heat treatment or high heat input welding of normal or high carbon austenitic stainless steels will cause sensitization, ie formation of chromium carbides. The formation of carbides not only reduces the corrosion resistance of the stainless steel but also tends to form martensite around the carbide. This martensite is magnetic and the more severe the sensitisation, the stronger are the magnetic properties. When nickel is added, for instance, the austenite structure of iron is stabilized. This crystal structure makes such steels non-magnetic and less brittle at low temperatures. Martensitic stainless steels are magnetic. *Wrought, austenitic stainless steels, such as 304 and 316, are generally regarded as non-magnetic in the annealed condition, ie they are not attracted significantly by a magnet. However, if they are cold worked they will be attracted to a permanent magnet. The change occurs because the cold work deformation induces a transformation of the microstructure from austenite to martensite. The effect is less marked in alloys with high concentrations of austenite stabilisers such as nickel, nitrogen and carbon. Once the martensite is formed, it may also become magnetised. *In contrast to the austenitic alloys, ferritic stainless steels such as 409 or 3Cr12/5Cr12 and martensitic stainless steels such as 420, are strongly attracted to a magnet even in the annealed state. The duplex and super-duplex stainless steels will also be strongly attracted because they contain about 50% ferrite in their microstructure. *
Q:How do steel coils compare to other types of metal coils?
Steel coils are widely regarded as superior to other types of metal coils due to their exceptional strength and durability. Steel is known for its high tensile strength, which means it can withstand heavy loads and resist deformation. This makes steel coils ideal for applications that require a high level of structural integrity, such as in the construction and automotive industries. In addition to their strength, steel coils also offer excellent corrosion resistance. Steel can be coated with various protective layers, such as zinc or paint, to prevent rusting and ensure longevity. This makes steel coils suitable for outdoor and marine environments where exposure to moisture and harsh weather conditions is common. Furthermore, steel coils have a wide range of mechanical properties, which can be tailored through different manufacturing processes. This allows for the production of steel coils with specific characteristics, such as high ductility, heat resistance, or electrical conductivity, to meet the requirements of various industries. Compared to other metal coils, such as aluminum or copper, steel coils often have a lower cost. Steel is one of the most economical metals available, and its abundance in nature contributes to its affordability. This makes steel coils a cost-effective choice for many applications, especially when large quantities are required. Overall, steel coils stand out due to their exceptional strength, durability, corrosion resistance, versatility, and affordability. These characteristics make steel coils a preferred choice for a wide range of industries, from construction and manufacturing to transportation and energy.
