Q: why do you need to heat steel when hardening, molecules etc etc: Gary is right, but maybe I can simplify it. It's very complex..... When you heat (hardenable) steel the carbon and iron form crystalline structures. Martensite and Austenite are most prominent, but there are others. Those are the hard crystals. When you quench it, those structures don't have time to dissolve as they would with slow cooling, so you freeze the crystalline structure in that state. Since that is too hard for most things, you temper it. Heating to a certain temp lets ~some~ of the crystals dissolve away. Annealing is heating and letting it cool slowly, so those structures will break up back into carbon and iron, leaving the steel soft. It's like a little atomic machine - crystals form, dissolve away, form again, with heat. It's waaaaay deeper than just that in detail, but that's the gist of it.

Q: How are steel coils used in the production of electrical motors?: Steel coils are used in the production of electrical motors as they serve as the core component of the motor's electromagnetic system. These coils are wound around a laminated steel core to create an electromagnet that generates the magnetic field required for the motor's operation. The steel coils, when energized with electric current, produce a magnetic field that interacts with the stator and rotor to facilitate the conversion of electrical energy into mechanical energy.

Q: Steel sticks- it has meaning to us -similar to my deceased father's name, Steven fits our style as people. We like the hardness of it for our little man. We need a middle name though. Open to suggestions, thank you=): Steel Keith Tompkins Steel Caleb Tompkins Steel Jude Tompkins Steel Lukas Tompkins Steel Ezekiel Tompkins Steel Cole Tompkins Steel Colin Tompkins Steel Lars Tompkins

Q: How can defects in steel coils be detected?: Defects in steel coils can be detected through various methods such as visual inspection, ultrasonic testing, magnetic particle inspection, eddy current testing, and radiographic testing. These techniques help identify surface defects, internal flaws, cracks, or any other abnormalities that may affect the quality and strength of the steel coils.

Q: What are the dimensions of steel coils used in the household appliance industry?: The dimensions of steel coils used in the household appliance industry can vary depending on the specific application and requirements. However, standard dimensions for steel coils commonly used in this industry range from 0.4mm to 3mm in thickness and 600mm to 1500mm in width. The length of the coils can also vary, typically ranging from a few hundred meters to several kilometers. These dimensions ensure that the steel coils are suitable for various household appliance manufacturing processes, such as forming, stamping, and welding. It is important to note that these dimensions are not fixed and can be customized based on the specific needs of the appliance manufacturer.

Q: They say it's some six times stronger than steel. need some explanation.: Most importantly, spider silk is extremely lightweight: a strand of spider silk long enough to circle the Earth would weigh less than 500 grams (18 oz). Spider silk is also especially ductile, able to stretch up to 140% of its length without breaking. It can hold its strength below ?40 °C. This gives it a very high toughness (or work to fracture), which equals that of commercial polyaramid (aromatic nylon) filaments, which themselves are benchmarks of modern polymer fiber technology. What this means in regard to what you have heard is that if you compared the tensile strength (type 'tensile strength' on wikipedia if you do not know what it means) of spider silk and a strand of steel at the same thickness, the silk would have a higher tensile strength than many grades of steel, upto that of high grade steel - of which they are about the same.

Q: I just want regular steel, not stainless steel.: If it rusts, magnetic, hard, heavy with high melting point I reckon yourve found mild steel.

Q: is it much difference between 1095 and 1080,,,1065,,,1060 or even 1045 steel?please help and thanks!: The guy below me obviously has no idea WTF he's talking about. It does NOT have anything to do with the edge angle at which the blade is sharpened. It does NOT have to do with heat treating. Both of these things are important, but they won't determine the type of steel. I'll try to help. 1095 is one of the best performing steels, against carbon steel or stainless steel, in the world. It's incredibly hard, holds its edge well and comes to a beautiful edge when sharpened correctly. As you know though, carbon steels need to be properly maintained to avoid rust/corrosion. Out of the steels you listed I'll give a brief summary of each steel... -1095 (Great all around steel, but is brittle by comparison to the others. This doesn't mean it will chip easily, but the other steels can take more of a beating. That being said, this is going to take a nicer edge, and hold it longer.) -1080 (A little bit more flexible and less liable to chip than 1095. A good compromise between edge retention/quality and ruggedness. -1065 (Commonly used in machetes and other heavy duty bush tools. Takes a decent utility edge and is highly unlikely to chip) -1060 1045 (Both extremely flexible and soft in comparison to 1095. Unlikely to chip, but it takes a crude edge. This edge will cut, but not like 1095 will.) Go with 1095. My favorite knife I own is in 1095 and serves me well everytime I head off into the woods. Keep some Rem-Oil on that bad boy though.

Q: How do steel coils contribute to sustainability in manufacturing?: There are several ways in which steel coils contribute to sustainability in manufacturing: 1. Recycling plays a crucial role: Steel is one of the world's most recycled materials, boasting a recycling rate above 90%. Steel coils are made from recycled steel and can be recycled again at the end of their lifespan. This reduces the reliance on raw materials extraction, conserves natural resources, and decreases energy consumption and greenhouse gas emissions associated with steel production. 2. Durability is a key factor: Steel is renowned for its strength and durability. Steel coils are specifically designed to withstand heavy loads, extreme temperatures, and harsh environmental conditions. Consequently, products made from steel coils, such as automotive parts, construction materials, and appliances, have a longer lifespan. This diminishes the need for frequent replacements and minimizes waste. 3. Energy efficiency is improved: Steel coils are utilized in various manufacturing processes, including stamping, forming, and welding. These processes require less energy when working with steel coils compared to other materials. Steel's high strength-to-weight ratio allows for the production of lightweight yet strong components, reducing energy consumption during transportation and enhancing fuel efficiency in vehicles. 4. Emissions are reduced: Steel coils contribute to sustainability by assisting manufacturers in lowering their emissions. Steel is a low-carbon material, emitting fewer greenhouse gases compared to materials such as aluminum or plastics. By employing steel coils, manufacturers can reduce their carbon footprint and contribute to climate change mitigation efforts. 5. The circular economy is promoted: Steel coils play a crucial role in the circular economy, which aims to minimize waste and maximize resource efficiency. Steel coils can be easily recycled and reused, ensuring their continued presence in the production cycle. This diminishes the need for virgin materials and encourages a more sustainable and circular approach to manufacturing. To conclude, steel coils make significant contributions to sustainability in manufacturing by being recyclable, durable, energy-efficient, emission-reducing, and promoting a circular economy. By selecting steel as a material and utilizing steel coils, manufacturers can take significant steps towards reducing their environmental impact and fostering a more sustainable manufacturing industry.

Q: I have a set of steel pans with copper bottoms. When I cook with oil it always burns the oil to the pan and takes days to clean. I don't think I should use steel wool, since it might scratch the surface. Does anyone know a faster way to clean scorched oil off a steel pan?: they have drywall (mudding) sponges to sand mud when you fix walls in the house, they are grey, square, and do not scratch. They seem to work better than any scrubber ever. Make sure you use a degreaser dishsoap like dawn. Maybe try putting your heat lower in the pan and cooking things more slowly?
