Q: For some reason, if you rub iron oxide or lodestone (both very crumbly, dark, mineral-like materials) into soft, unhardened steel, their particles actually get stuck into the surface of the steel (that is, darkening it). My question is, how does this work? How come iron oxide and lodestone can get stuck, and how come other materials (like silicone carbide, for example) do not?My second question is, are there any materials that can get stuck into steel, that is also blue in color, and how would I best obtain it?
If you look at the surface of untreated steel even with a low power microscope you will see a surface that is far from smooth, there are pits and occlusions dotting the surface. Steel is not polished when you see it this way so the only treatment to the surface was the extrusion process or forming done on it by the presses. Iron oxide has a very small particle size and when pulverized into a powder it can easily fill the pits and voids in the steel surface coloring it.
Q: I want to start getting throwing knives and i was wondering what material is best for quality, but still cheap. I also saw some 440 stainless steel knives that i liked and wanted to know if the material was good
Good steel ain't cheap, cheap steel ain't good... If you're just starting out (practicing anyways), I would be less concerned about the material and more concerned about the style and shape of the blade to gain consistency in your technique... When you start getting proficient for competitions and such... then I'd start investigating steel grades... Anyways, here's a summary from the wiki: Type 440—a higher grade of cutlery steel, with more carbon, allowing for much better edge retention when properly heat-treated. It can be hardened to approximately Rockwell 58 hardness, making it one of the hardest stainless steels. Due to its toughness and relatively low cost, most display-only and replica swords or knives are made of 440 stainless. Available in four grades: 440A, 440B, 440C, and the uncommon 440F (free machinable). 440A, having the least amount of carbon in it, is the most stain-resistant; 440C, having the most, is the strongest and is usually considered more desirable in knifemaking than 440A, except for diving or other salt-water applications.
Q: What are the different methods of testing the mechanical properties of steel coils?
Testing the mechanical properties of steel coils can be done through various methods, which play a critical role in determining the steel's strength, ductility, and overall quality. Some commonly employed techniques include the following: 1. Tensile testing: This method involves applying a force to a steel coil until it breaks. It measures the maximum stress the material can endure before fracturing, as well as its elongation and reduction in cross-sectional area. Tensile testing provides valuable information about the coil's ultimate tensile strength, yield strength, and elongation. 2. Hardness testing: This test determines a material's resistance to indentation or scratching. Multiple methods, such as Brinell, Vickers, and Rockwell hardness tests, can be employed to measure the hardness of steel coils. These tests offer insights into the steel's ability to resist deformation and wear. 3. Bend testing: Bend testing involves subjecting a steel coil to controlled bending until it reaches a specific angle or a crack appears. This test evaluates the coil's ductility, flexibility, and its resistance to cracking or fracturing under bending stress. 4. Impact testing: Impact testing gauges a steel coil's capacity to absorb energy when exposed to sudden shocks or impacts. The Charpy impact test is the most commonly used method, wherein a notched specimen is struck by a pendulum hammer, and the energy absorbed during fracture is measured. This test assesses the coil's toughness and resistance to brittle fracture. 5. Fatigue testing: Fatigue testing entails subjecting a steel coil to repeated or cyclic loading to simulate the stresses it may experience during its intended use. This test evaluates the coil's ability to withstand repeated stress over an extended period and its resistance to fatigue failure. 6. Ultrasonic testing: Ultrasonic testing utilizes high-frequency sound waves to detect defects or flaws within the steel coil. This non-destructive testing method can identify internal or surface defects like cracks, voids, or inclusions that may impact the steel's mechanical properties. It is worth noting that these testing methods typically adhere to industry standards and specifications, such as those set by ASTM (American Society for Testing and Materials) or ISO (International Organization for Standardization). This ensures the accuracy and reliability of the results obtained.
Q: How are steel coils used in the manufacturing of electrical components?
Steel coils are used in the manufacturing of electrical components as they provide a strong and reliable core for various types of transformers and inductors. These coils are often wound around a steel core to enhance magnetic properties and improve efficiency, allowing for the transformation and transfer of electrical energy.
Q: How is the quality of steel coils determined?
The quality of steel coils is determined by various factors including the chemical composition, mechanical properties, surface finish, and dimensional characteristics of the coils. Additionally, factors such as the manufacturing process, heat treatment, and adherence to industry standards and specifications also play a significant role in determining the quality of steel coils. Thorough testing and inspection procedures, such as visual inspections, hardness tests, tensile strength tests, and non-destructive testing methods, are employed to ensure the quality and reliability of steel coils.
Q: I have a mountain bike w/ 26 wheels. My question is what's the biggest difference between aluminum vs. steel? If most of my riding is off-road, wouldn't the steel wheels be stronger/more durable?
Short answer: Aluminum is lighter and stiffer than steel. Steel is stronger but flexier. However, the technology used to make mountainbike wheels has become very advanced that it is possible to make very strong and reliable aluminum wheels that are at the same time light. Mavic and Sun Ringle make strong and light wheels. You may want to check your local bike shop for their recommendations for your style of riding.
Q: Can steel coils be stored in a humid environment?
Steel coils should not be stored in a humid environment as it can lead to corrosion and damage to the steel.
Q: What are the disadvantages of using steel coils?
One of the main disadvantages of using steel coils is their weight, which can make transportation and handling more challenging and costly. Additionally, steel coils are prone to corrosion if not properly coated or protected, which can negatively impact their lifespan and performance. Another downside is their limited flexibility and difficulty in shaping, which may restrict their application in certain industries. Lastly, steel coils can be expensive to produce and acquire, making them less cost-effective compared to alternative materials in some cases.
Q: iam talking abt carbon steel of composition:-C=0.15wt% Mn=0.60wt% P=0.035wt% S=0.04wt% Cu=0.20 (min)wt%....
The composition you mention is not a low carbon steel.The carbon and manganese content are high enough to mean that the crystal grain size will be small. A very large grain size is needed in steels for transformers,motors etc.The large grain size and lack of carbides in low silicon steels for magnetic purposes allows the easy movement of magnetic domain walls.Transformer steels typically have a carbon content of about 0.003% and 3.5%Si with the phosphorus and sulphur at a tenth of the levels you mention.The high Si content increases the electrical resistivity of the magnetic core and reduces the power loss from eddy currents(the core metal has voltages generated in it by the changing magnetic fields) and the power lost in eddy currents heats up a transformers core so it needs extra cooling;the loss is inversely proportional to the resistivity and 3.5%Si increases resistivity of iron by a very large amount.The presence of high silicon with ultra low carbon and manganese level allows the soft magnetic steels to be annealed at very high temperatures(850 to 1100deg C)without a phase change so that the crystals have 10,000 to 10,000,000 times the volume of the crystals in heat-treatable (Just)steel you mention.Fine for playing with and demonstrating electromagnetism but not as electrical engineering feedstuff.
Q: What are the common coil slitting equipment used in the industry?
The common coil slitting equipment used in the industry include slitter rewinders, rotary shear slitters, and loop slitting machines. These machines are designed to efficiently cut and rewind large coils of material into smaller, narrower coils for various industrial applications.
