Q:How are steel coils used in the production of electrical motors?
Steel coils are used in the production of electrical motors as the core component of the motor's electromagnet. The coils are wound around an iron core to create a magnetic field when electricity flows through them. This magnetic field interacts with other components in the motor to generate mechanical power, allowing the motor to function efficiently.
Q:Cast steel welding
Normal okorder /.. Mild steel and cast steel produces a very long stream of brilliant sparks, with some forking. CI produces much shorter, dull reddish sparks and the volume of sparks is much less. many highly branched or intermittent sparks will be seen.
Q:How do steel coils contribute to fire resistance in buildings?
Steel coils contribute to fire resistance in buildings in several ways. Firstly, steel coils have high melting points, which means they can withstand extremely high temperatures without losing their structural integrity. This helps prevent the collapse of the building during a fire. Additionally, steel coils have low thermal conductivity, meaning they do not readily transfer heat. This property helps to contain the spread of fire, preventing it from spreading rapidly within the building. Moreover, steel coils can be used to reinforce concrete structures, enhancing their fire resistance. By providing strength and stability to the building, steel coils play a crucial role in ensuring the overall fire safety of the structure.
Q:What is the cost of steel coils?
The cost of steel coils can vary depending on factors such as size, quality, and market conditions. It is best to contact a supplier or check current market prices to get an accurate cost.
Q:i have recently gotten into DIY and am planning on making my own knife. My question is what kind of steel would be good to use for heat treating if i plan on using water and not oil in the process.
Go to junkyard get old leaf spring, cut out knife, start sharpening. Why waste time heat treating steel when the spring steel as already be done.
Q:I was cutting a sheet of steel with an angle grinder when suddenly the rate at which the blade was cutting slowed way down. I tried a few different things, and turned off the tool and looked at the blade. It didn't look damaged, but it definitely was not cutting as quickly. I thought either I had hit a harder section of steel (is that possible? It looked pretty uniform) or the blade had lost it's abrasive quality or something. Also, before this happened I had accidentally cut into the wooden sawhorse that was holding up the steel sheet, but I've done that before with no problem. After a short while the problem fixed itself and the rate of cutting went back to a fast normal. Anyone know why this happened?
Sounds like the abrasive surface got blinded, coated with something that prevented the abrasive particles from touching the steel. It is possible to have vastly different hardnesses in a single piece of steel. Case hardening, carburizing, induction hardening, heat affected zone from welding, differences in work hardening, and presence of inclusions are some of the things that can create hardness variation within a single piece. But... sounds like you are working with a sheet which is unlikely to have any of these conditions. So... it was probably the grinding disk
Q:I have a knife with AUS8 Stainless Steel. No idea what that means. I want to know some of the best stainless steels for knifes and all you can tell me about stainless steel would be great. I was browsing google and looking at grades and had no idea what all the numbers meant. Thanks!
Actually-good grades of stainless is superior to high carbon steels which has been proven by countless tests. Aus8 is a japanese steel from what I know, so I'm not sure what the letter and number designation means. From what I know, Aus8 has similar properties to 440B though with a carbon content of around ~.74%. This is lower content then most other blade steels meaning it has lower edge retention. The stainless steels I'd consider to be best are: Ats-34: Less corrosion resistant then 440c, but is tougher then 440c and still holds a edge quite well 440c: Probably the best all around steel on the market for its price. Highest corrosion resistance and very good edge retention. I wouldn't recommend it on choppers though, a tougher steel like the one mentioned above would probably be better for that. A/B/C indicates the carbon content going from least to greatest. 4xx indicates that its a chrome martensitic steel. 40 indicates that its a high carbon grade compared to (4)20 which has less then .5 percent. CpmS30v: Slightly lower corrosion resistance then 440c due to it not taking a mirror finish, but very high edge retention and improved toughness. Cpm indicates that it's made by compressed particle metallurgy while the v indicates that its a vanadium alloy. I'm not sure what the S30 indicates.
Q:Just wondering how good are forge steel screw drivers, tool boxes(organisers) and pliers are, as screw fix are having a january sale, and looking to add to my tool collection. Thanks in advance

Q:How are steel coils inspected for hardness?
Steel coils are inspected for hardness using various methods to ensure their quality and suitability for specific applications. One common method is the Rockwell hardness test, which involves pressing a diamond or ball indenter into the surface of the coil and measuring the depth of indentation. The hardness value is then determined based on the depth measurement. Another method used is the Brinell hardness test, which employs a hardened steel or tungsten carbide ball indenter to create an indentation on the coil's surface. The diameter of the indentation is measured, and the hardness value is calculated using a formula based on the applied load and the diameter of the indentation. Vickers hardness test, on the other hand, uses a pyramidal diamond indenter to create an indentation on the coil's surface. The indentation diagonal lengths are measured, and the hardness value is calculated using a formula based on the applied load and the diagonal lengths. Apart from these traditional methods, modern technology has introduced non-destructive testing techniques such as ultrasonic testing and eddy current testing. Ultrasonic testing involves transmitting ultrasonic waves through the coil and measuring the time taken for the waves to return. Changes in the wave pattern can indicate variations in hardness. Eddy current testing uses electromagnetic induction to detect changes in electrical conductivity, which can be correlated to hardness variations in the steel coil. Overall, steel coils undergo rigorous inspection processes using a combination of traditional and advanced techniques to ensure their hardness meets the required specifications. These inspections play a crucial role in maintaining the quality and reliability of steel products in various industries.
Q:What are the common surface defects found in steel coils?
Steel coils can have several surface defects commonly found. One prevalent defect is rust or corrosion, which happens when moisture contacts the steel surface and causes oxidation and rust formation. Another defect is scratches or abrasions, occurring during coil handling or transportation. These can vary from small surface scratches to deeper gouges that affect the steel's structural integrity. Surface roughness or unevenness is also possible due to improper rolling or cooling processes during manufacturing, resulting in inconsistent surface texture that affects appearance and performance. Scale is another defect, forming an oxide layer during manufacturing, giving the steel a rough and uneven look. Finally, oil or grease stains may occur during manufacturing or handling, impacting paint or coating adhesion. These common surface defects impact steel quality, appearance, and performance, often requiring cleaning, grinding, or recoating as remedial actions.
