Q: How do steel coils compare to other materials, such as aluminum or copper?: Steel coils have several advantages over other materials such as aluminum or copper. Firstly, steel is generally stronger and more durable, making steel coils less prone to damage or deformation. Additionally, steel has better heat resistance and can withstand higher temperatures, making it suitable for a wider range of applications. Steel coils also tend to be more cost-effective compared to aluminum or copper, making them a popular choice in various industries.

Q: if steel is heated from room temperature (20c) to (500c) what would be the change in density?coefficient for linear expansion of steel 12x10^-6 k density of steel 7800 kg: First you have to convert the coefficient of linear expansion to a coefficient of volumetric expansion. Multiply the coefficient of linear expansion by 3: Coefficient of expansion of steel,β:12E-6/°K x 3 = 36E-6/°K Difference in temperature: 480°K ΔV = VoβΔT ΔV = Vo x (0.000036) x 480 ΔV = 1m? x 0.017 ΔV = 0.017m? Originally, the steel was at 7800 kg/m? Now, the steel was at 7800 kg/ 1.017m?, or 7670 kg/m? Change in density = 7670 - 7800 = -130kg/m?

Q: I've been looking for lots of info on this steel. Cold Steel uses it now in their knives replacing the AUS-8 steel. I was hoping somebody had a knife with this steel who could give me some real first hand knowledge not just numbers. Thanks!: Before I answer I must let you know that I have been a knife collector for 17 years, and have a great assortment of specialty and antique folding knives. As for your question, I wouldn't worry too much about it. The first answerer is very knowledgeable in this category. But in the real world, the steel chemistry of folding knives will never be as important as that of fixed blades or kitchen knives. The fact that manufacturures go through great lengths to advertise their superior steel is just for sales and bragging rights. When it comes down to it, a pocketknife might be useful, but it is never the best tool for the job. It is a compomised design from the beginning. If you need to cut a steak, a steak knife will do. A box cutter works best on cardboard. A razor works best for shaving, wire cutters best for cutting wire, an axe for chopping wood...I could go on. A pocket knife is never going to perform better than the real thing ( although I do prefer the can openers on Swiss army knives than real can openers). As for self defense, minus the concealability factor, a folding knife sucks compared to a fixed blade. But if you were to pull one out during an extreme circumstance, I doubt anyone is going to be effected by the Rockwell hardness.

Q: What are the main factors that affect the quality of steel coils?: The main factors that affect the quality of steel coils include the composition and purity of the steel used, the manufacturing process and techniques employed, the temperature and time of the heat treatment, the level of mechanical stress and strain during rolling and cooling, and the presence of any impurities or defects in the final product.

Q: I just got the game Red Steel for the Wii. I want to use the sword in multiplayer mode, but I can't find it. Is it only for single player?: Sure.

Q: How are steel coils inspected for defects?: To ensure the quality of steel coils meets required standards, various methods are used to inspect them for defects. Visual inspection is a common method, where trained inspectors examine the coil's surface for visible defects like cracks, scratches, or dents. This can be done through direct observation or with the help of magnifying tools. Another method is magnetic particle inspection, which detects surface and near-surface defects like cracks or voids. Here, a magnetic field is applied to the coil, and magnetic powder is spread on the surface. If any defects are present, the powder will be drawn to them, making them visible to the inspector. Ultrasonic testing is also commonly employed to inspect steel coils for defects. It involves transmitting high-frequency sound waves into the coil and analyzing the reflected waves. Any deviations in the sound waves can indicate the presence of defects like cracks or voids within the coil. Eddy current testing is another method used to detect defects in steel coils. It works by using electromagnetic induction to generate eddy currents within the coil. Any changes in these currents caused by defects in the material are detected and analyzed by the inspector. Finally, in some cases, destructive testing is performed on steel coils. This involves taking a sample from the coil and subjecting it to tests such as tension or bend testing. These tests evaluate the mechanical properties of the steel and indirectly indicate the presence of defects. Overall, a combination of visual inspection, magnetic particle inspection, ultrasonic testing, eddy current testing, and potentially destructive testing is used to inspect steel coils for defects. These methods ensure that any defects are identified and addressed, guaranteeing the delivery of high-quality steel coils to customers.

Q: bullets are normally made out of lead...are there bullets that are completely steel?? (not plated): They will both knock it over, but it depends on how the bullets hit the block. If the steel bullet hits the block at any kind of an angle, it will knock it over because it will enter the block cross grain. If it hits it straight on, it will not have as much resistance as it goes with the grain of the wood. The rubber bullet will have more resistance because it does not pierce the block. The force from the rubber bullet would be the same no matter what angle it comes from.

Q: Can steel coils be stored in unheated warehouses?: Yes, steel coils can be stored in unheated warehouses as long as proper precautions are taken to prevent moisture and corrosion.

Q: What are the different methods of coil edge trimming?: There are several methods of coil edge trimming, including shearing, slitting, and laser cutting. Shearing involves cutting the edges of the coil using a large blade or shear. Slitting involves making multiple cuts along the coil's edges using a slitting machine equipped with circular blades. Laser cutting uses a high-powered laser beam to precisely cut the coil's edges. Each method has its own advantages and is chosen based on factors such as the material being trimmed and the desired precision of the cut.

Q: If rebar steel is welded together as opposed to 'tied' does it decrease the strength of the steel?: Gary is right on! To add to it some rebar is heat treated if you weld it it loses the heat treating if you don't re heat treat it it will fail at the welded joint.
