Q: Ok I have a neodymium magnet, stuck to my fridge holding a old bottle cap opener for my beer it works fine. At the local rummage sale there was a beautiful cap opener my freind was selling for $0.25 she said had never beenUsed it was like 40 years old it is made a stainless steel. The magnet will not stick to it. I don't understand this looked this up and certain steels are not magnetic, I tried a experiment with my compass it don't point north as should it follows the bottle opener as I move it around it. If not magnetic why is this happening? Also tried placing near another neodymium magnet with a pull of about 200 lbs. Not I tiny bit of attraction to the metal. If so why is the tiny magnet in the compass attracted to it. But not a huge powerfull magnet.: That's interesting that it caused deflection in the compass. A lot of stainless steels may be SLIGHTLY magnetic, because they have small amounts of ferrite or alpha-iron in them. Ferrite is one of the crystal phases of steel. It has a body-centered cubic (BCC) structure and it's responsible for the magnetism of ordinary steels. Adding certain elements like nickel, manganese, or molybdenum, changes the crystal structure of the steel to a face-centered cubic (FCC) structure, which is NOT magnetic. This crystal phase is known as Austenite or gamma-iron. However most iron alloys contain some impurities that may cause the steel to be not completely transformed into the FCC austenite phase, small areas remain as ferrite.

Q: How are steel coils used in the production of electrical connectors?: Steel coils are used in the production of electrical connectors as they are often used as a raw material for manufacturing the connector pins. The steel coils are typically shaped and cut to specific dimensions to create the pins, which are then inserted into the connectors to establish electrical connections.

Q: Aluminum and Steel brittle or ductile based on these results? and why? Steel Aluminium% Elongation 0.2510.2705Modulus of E in ksi11833.33964.71Tensile Strength (ksi)87.5 51.5Yield Strength (ksi)78.5 41: Only steel(of this pair)might be liable to brittle fracture,which would be implied by almost zero elongation or reduction in area at fracture.On this basis the steel has not failed by brittle fracture.I would expect much more elongation in pure aluminium than your sample shows so I presume it to be brittle unless it is an alloy rather than commercially pure aluminium.However brittle fracture in metals is a particular phenomenon to be determined by impact tests and examination of fracture surfaces and is particularly relevant to metals with the body centred crystal structure.

Q: How are steel coils used in the production of steel cables?: Steel coils are used in the production of steel cables by being unwound and straightened to form individual wires, which are then twisted or braided together to create the cable.

Q: How are steel coils used in the manufacturing of agricultural irrigation systems?: Steel coils are used in the manufacturing of agricultural irrigation systems as they are shaped and formed into pipes, tubes, or other components that are essential for transporting water from the source to the fields. The coils provide strength, durability, and corrosion resistance, ensuring that the irrigation system can withstand the harsh agricultural environment and last for a long time.

Q: I do a lot of scrapping and would like to be able to separate stainless steel from regular steel. The magnet test doesn't always work since stainless can be magnetic, but what are some ways that I can for sure tell the difference? Or even something like a sound that they make that may help me to tell the difference.: Stainless steel uses chromium in its mixture to thwart the affects of corrosion. General steel, or carbon steel, is generally almost completely iron and is used for far greater applications than stainless steel. Stainless steel is used mostly in kitchen appliances, utensils, etc... The best thing I can come up with is to find a way to measure the chromium content of the steel you are looking at. If it's around 3% chromium, it's probably standard steel. If it's somewhere between 10-15% chromium it's probably stainless steel (or even 4% plus). I can't tell you a fast and quick way to test the steel because from my research, it appears there are as many grades and allows of steel as there are uses for steel! There is one test I've seen for home testing surgical steel which is a higher grade stainless steel, that is to put scotch tape on one section of material then soak it in water for a 24 hour period, then let it air dry for 24 hours. You remove the tape and lightly polish the exposed areas to see if there was any discoloration or pitting on the exposed area. This test is mainly for surgical steel jewelry, however stainless steel is supposed to resist rusting more than standard steel, hence it might work for other steel types as well. You may have to read some of the other links below to get some other ideas on how you can test steel to see if it is stainless.

Q: I have my grandpa's navy knife from ww2, a mk2 combat knife i think, and i was wondering what type of steel it is made of. I'm guessing it's a high carbon steel, i'd just like to know exactly what grade.: I would get a 1095, serrated edge, tanto style, with either a good quality rubberized or bone handle.

Q: What are the safety precautions to be followed while handling steel coils?: When handling steel coils, there are several safety precautions that should be followed. These include wearing appropriate personal protective equipment, such as gloves and safety glasses, to protect against cuts, abrasions, and eye injuries. It is important to use proper lifting techniques and equipment to prevent strains or back injuries. Steel coils should be securely stacked and stored to prevent them from falling or rolling, and caution should be exercised when moving or transporting them to avoid accidents. Additionally, workers should be trained on the safe handling and storage procedures specific to steel coils to minimize any potential hazards.

Q: How do steel coils differ in terms of size and weight?: Steel coils can vary greatly in terms of size and weight depending on their intended use and production process. The size of a steel coil is typically measured in terms of its outer diameter, inner diameter, and width. The outer diameter refers to the total diameter of the coil, while the inner diameter refers to the diameter of the hollow center of the coil. The width of the coil refers to the distance between the two flat sides of the coil. In terms of weight, steel coils can range from a few hundred pounds to several tons. The weight of a coil is primarily determined by its size and the type of steel used. Coils made from high-strength steel tend to be heavier due to their higher density, while coils made from lower-grade steel can be lighter. The size and weight of steel coils are crucial factors in determining their transportability and handling. Smaller and lighter coils are generally easier to handle and transport, making them more suitable for applications where maneuverability is important. On the other hand, larger and heavier coils are often used in industries where strength and durability are essential, such as construction and automotive manufacturing. Overall, steel coils can vary significantly in terms of size and weight, allowing for a wide range of applications and customization to meet specific requirements in various industries.

Q: How are steel coils used in the manufacturing of railway wagons?: Steel coils are used in the manufacturing of railway wagons as they serve as a raw material for various components such as the wagon body, chassis, and structural parts. These coils are processed, cut, and shaped to form the required parts, ensuring the wagon's strength, durability, and load-bearing capacity. The steel coils are transformed into sheets, plates, or beams, which are then welded, bolted, or riveted together to construct the wagon's framework and body. Overall, steel coils play a vital role in providing the necessary strength and structural integrity to railway wagons.
