Q: I plan to buy a bushcraft knife ..The blade made up by damascus steel.My question is ,is damascus steel is very strong ?: Ok, lets define what is Damascus steel. The modern Damascus is basically any steel that shows a pattern. Patterns are accomplished by 1. manipulating the crystal structure or 2. by combining 2 or more different alloys together. The blade you are looking at is referred to as a pattern welded blade. Damascus is only as strong as it's base components + heat treat and design. The strongest will be obtained by combining high carbon and low carbon steels. I do this by using steel cable. The patterns aren't real bold but are interesting none the less. To break it you must brake the hard steel and tear through the soft iron. The laminated stuff works the same way. For greater edge holding I use all high carbon, varying alloy content from simple carbon to chromium/nickle alloys. These are what you normally find in pattern welded blades. A fine pattern that has many lamination's crossing the edge will offer the best edge holding. Properly done one can get the DCE or damascus cutting effect where the soft layers wear away faster than the hard layers almost making the blade self sharpening. Is that blade good? Buy it if you like it, it won't compare to a well made hand forged blade but is much cheaper. sorry for the overload.

Q: What are the different methods of coil packaging for steel coils?: Steel coils can be packaged using various methods, each with its own advantages and suitability for specific applications. Some commonly used methods include: 1. Strapping: Steel or plastic strapping is used to secure the coil and prevent unwinding or shifting during transportation. Strapping can be done manually or with strapping machines, providing a reliable and cost-effective packaging solution. 2. Stretch wrapping: This method involves tightly wrapping the coil with a stretch film. The film is stretched and wrapped around the coil, offering protection against dust, moisture, and damage. Stretch wrapping is suitable for lightweight coils and provides good visibility of the product. 3. Steel banding: This robust and heavy-duty method uses steel bands to secure the coil. It ensures high strength and durability, keeping the coil intact during transportation or storage. 4. Edge protectors: To safeguard the edges of the coil, edge protectors made of cardboard or plastic are used in combination with other packaging methods. These protectors provide additional support to prevent edge damage. 5. Wooden crates: For heavy or fragile steel coils, wooden crates are often used to provide maximum protection. The coils are placed inside the crate and secured with strapping or steel banding. Wooden crates offer excellent strength, stability, and can be customized to fit specific coil dimensions. 6. Paper interleaving: This method involves inserting layers of paper or cardboard between individual wraps of the coil to prevent scratching or marking. Paper interleaving is commonly used when stacking coils or when protecting a high surface finish. 7. Automated packaging systems: In larger-scale operations, automated packaging systems can be used. These systems are designed to handle and package coils using various methods such as strapping, stretch wrapping, or steel banding. They ensure increased efficiency, productivity, and consistent and secure packaging. The choice of coil packaging method depends on factors including coil size and weight, transportation requirements, required level of protection, and cost considerations. It is crucial to select the appropriate packaging method to ensure the safe delivery of steel coils to their destination.

Q: I am making a permanent magnet, just for fun. I am trying to find the best grade of steel to do so with.: The type of steel you require is Steel ( Iron + Carbon, mainly.),{many different types of steel } with a high Cobalt and Nickel content. These alloyed together give the best Permanent Magnets, mainly due to their own individual magnetic properties / characteristics being retained in the Alloy. All 3 metals can be magnetised by there own, but Cobalt is known to cause cancer. Nickel, is poisonous and can also cause sever Dermatitis and the destruction of skin tissue.But when alloyed together with Iron they are pretty harmless. Interesting thing is, All of these metals (in this case Elements) can share the same Mass Number ( 60 ). And yet are totally different in their other properties beside Magnetism. Cobalt - Samarium - alloys, create some of the worlds most powerful permanent magnets. And were used in medicine, But are now superseded by Neodymium magnets which are employed instead. Edit; What you could try is, mild steel which is widely available and easily found. . The steels mentioned above are pretty exclusive materials and I personally would not know how to test for their contents, of which they are made from. Soft Iron is good for making electro-magnets if you fancy a go at making one. .
