Q: I want a good quality, big, strong, steel knife but I want it to be a good price, say around $30 or less, $60 at the most. please add links.: DAGS for combat knife

Q: i always have eaten rolled oats and i have never tried steel cut oats. what are your opinions on them for oatmeal and which do u like better?: Steel cut oats contain more nutrients because they have not been processed.

Q: I know some .50 Cal BMG will do that, but what are some other cartridges ?Also, are all steel plate the same hardness ?: Steel plate and steel plate armour are two different grades of steel, and normally nearly anything will go through steel plate. Chetak

Q: What kind of steel should be used for constructing a steel building?: In steel construction there are many standard types of steel used. Lots of different factors contribute to your steel choice. How tall is the building? Are you in an earthquake zone? Steel for the columns, or the beams? You might want to refer to the American Institute of Steel Construction for more information, they are the governing body in the US.

Q: what is the chemical process that makes steel harder when it is heated and cooled rapidly?what does the heating of it do to the atoms?what does the cooling of it do to the atoms?what makes tempered steel so strong compared to untempered steel?: You can't temper all steels. Generally the material must be a high-carbon or tool steel. Different alloys temper differently, and tempering is usually done to get a specific set of characteristics, so you must know what you are working with and use the right methods and temperature. If you do it wrong, the material may be hard but too brittle for the purpose or have other issues. It can be simple, such as heating to a dull red, carbonizing the surface (use an acetylene rich flame until it blackens the surface) and oil quenching. Do that to a piece of tool steel (like a screwdriver) and it will case (surface) harden it to the point you can't scratch it with a file. Tempering changes the way the molecular structure in the metal is linked and oriented.

Q: How are steel coils used in the manufacturing of medical equipment?: Steel coils are used in the manufacturing of medical equipment as they provide strength, durability, and flexibility for various components. These coils are often used in the production of surgical instruments, medical devices, and diagnostic equipment where precision and reliability are crucial.

Q: How are steel coils used in the production of steel brackets?: Steel coils are used in the production of steel brackets by being processed and cut into the desired shape and size. The coils serve as the primary raw material, providing the necessary strength and durability for the brackets.

Q: Can anyone tell me what that means. I have seen it on knife blades an such. I am assuming it's a formula for the strength of the metal. who does that scale work, and please keep it simple.: The number just indicates which class of steel alloy it belongs. Yours happens to be a 400 series and happens to have no Nickel in it (440 Steel) and a higher amount of carbon (Nickel is very common in steel) When I say alloy, I'm referring to the different chemical formulas and processing of steel which vary for different uses like industrial use, medical use or decorative use. Think of the different alloys like the types of soft drinks out there. Coke, Pepsi and Dr. Pepper. They all have very similar chemical formulas; yet differ with their secret ingredients which is apparent in the taste.

Q: What are the different types of steel coil grades?: There are several different types of steel coil grades, including hot rolled coil (HRC), cold rolled coil (CRC), galvanized coil (GI), galvannealed coil (GA), and stainless steel coil.

Q: How are steel coils used in the production of structural components?: Structural components heavily rely on steel coils throughout the production process. These coils, made from rolled steel strips, serve as the essential raw material for manufacturing various components like beams, columns, and trusses. The initial step in utilizing steel coils for structural components involves uncoiling the strip and cutting it into desired lengths. This can be achieved using diverse cutting methods, such as shearing or sawing. Once the coils are cut into appropriate lengths, they undergo further processing to shape them into specific structural components required for a particular project. One prevalent approach to shaping steel coils into structural components is through bending or forming. This necessitates the use of specialized machinery to bend or shape the steel into the desired configuration. For instance, a steel coil can be bent into an I-beam shape, commonly employed as a load-bearing component in buildings and bridges. Another technique employed for shaping steel coils into structural components is welding. This involves joining multiple steel coils together to create larger components. Welding is often employed to fabricate components like columns or trusses, which demand the combination of multiple steel coils to achieve the required strength and structural integrity. Once the steel coils have been shaped and formed into the desired structural components, they may undergo additional processes, including surface treatment or coating, to enhance their durability and resistance to corrosion. This ensures that the components will endure and withstand the demands of their intended applications. In conclusion, steel coils are crucial in manufacturing structural components as they provide the necessary raw material. Through cutting, bending, and welding processes, steel coils are transformed into the specific components needed for various construction projects. These components play a vital role in supporting the structural integrity of buildings, bridges, and other structures.
