Q: why do you need to heat steel when hardening, molecules etc etc: Metalurgy is a fascinating science which has been used to mark the ages of civilization: the Bronze Age, the Iron Age, etc. Ancient sword makers heated steel until the polished surface showed a straw color (which we now know to be about 550°F, and due to surface oxides) and then plunged the blade into a tank of water. The blade was quickly removed, repolished, and observed closely for heat transfer from the core returning the surface to straw color. If so, it was quenched again. This technique left the surface hard without making the blade brittle. Today the steel crystal lattice is known to be either face centered cubic (iron atoms at the corners of a cube and iron atoms centered in the faces of the cube) or body centered cubic ( iron atoms at the corners of the cube and an iron atom at the geometric center of the cube). Most experienced machinists can estimate the temperature of steel from the color of its surface oxides.

Q: I heard on some shows that you can carbonise steel by heating it red hot then dropping it in black oil. i cant find this no where online, and the process for commercial carbon steel is totally different. can you really carbonise regular steel by heating it to red hot then dropping it in regular black oil. i saw it on mythbusters once. when the made carbon steel hammers to test if 2 hammers smashed together will shatter: in the experience that your speaking a pair of folding pocket knife, i think of that it somewhat is somewhat six one way and a 0.5 dozen the different. i actually do choose stainless for my pocket knives. i don't choose to grease a knife to the degree i've got faith carbon demands, basically to then stick it my pocket to entice dirt to the knife and oil to my pants. i'm the impressive opposite on sheath knives nevertheless. i admire 1095 carbon steel, uncomplicated part sheath knives. i will thrash on them difficult, and that i rarely have considerable part issues. of course, I require them to be lined with some style of powder coat or the like, with the aid of fact they might rust, yet I do attempt and save them sparkling and dry whilst in the sheath, so as that they gained't pit the uncoated part. My motives for this sheath knife selection is multi-fold. First, those knives are only much less costly. i don't spend $80 money on a exterior sheath knife. i take advantage of the gadget too difficult to choose to spend extra. i don't basically like the extra classic stainless steels alongside with AUS-8, 420HC, and 440C (to not point out the HORRENDOUS 440A) with the aid of fact i've got faith that the all else being equivalent, a stainless blade will bend till now a carbon blade will harm. I additionally think of that carbon holds an part a minimum of besides, if not extra suited, than classic stainless, and it somewhat is plenty extra handy to hone. i don't understand plenty approximately those new laminates, different than the very difficult, yet not so difficult. they seem probably too brittle for my use. That, mixed with the actuality that they harm the bank, ability that I only is only not pondering them.

Q: Molten steel changes to solid steel at its __________ point. Could you please fill in the blank? Thank you so much, it is greatly appreciated. I have been looking for the answer to this question for a long time, but I never understand what the websites are trying to say because I don't have that big of a vocabulary and don't know what they mean. I've seen things saying steel boiling point, steel melting point, and steel freezing point. I don't know what any of those mean, and they might be the answer. Please help me. Thank you.: Carbon 'tempers' steel, by making it harder and less prone to bending (ductility). It fits the carbon atoms into the spaces in between the crystal lattice structure of the iron atoms. Too much carbon means the steel becomes more brittle, harder to weld and thus more likely to shatter under stresses which are perpendicular (shear forces) to the crystal structure of the molecules. It also is very difficult to work, requiring very high temperatures.

Q: Can steel coils be coated with anti-microbial materials?: Yes, steel coils can be coated with anti-microbial materials. These coatings can help inhibit the growth of bacteria, fungi, and other microorganisms, making the steel coils more resistant to contamination and reducing the risk of transmission of harmful pathogens.

Q: How are steel coils used in the production of electrical conduits?: Steel coils are used in the production of electrical conduits as they serve as the raw material for manufacturing these conduits. The steel coils are processed and shaped into cylindrical tubes, which are then used to protect and enclose electrical wires, ensuring safe and efficient transmission of electricity.

Q: What are the different methods of welding steel coils?: Steel coils can be welded using various methods, each with its own advantages and applications. The most commonly used methods for welding steel coils are: 1. Resistance Welding: By applying pressure and electric current, this method generates heat and joins the steel coils. It is ideal for high-speed production and can be categorized into spot welding, seam welding, and projection welding. 2. Arc Welding: This technique involves creating an electric arc between an electrode and the steel coils, resulting in intense heat and metal melting. Different arc welding techniques include shielded metal arc welding (SMAW), gas metal arc welding (GMAW), and flux-cored arc welding (FCAW). 3. Laser Welding: Laser welding employs a highly focused laser beam to melt and join the steel coils precisely. It offers excellent control, high welding speeds, and minimal heat-affected zones, making it suitable for thin materials and complex designs. 4. Electron Beam Welding: This method uses a concentrated beam of high-velocity electrons to melt and fuse the steel coils. It is commonly used for welding stainless steel and other high-temperature alloys, providing deep penetration and minimal distortion. 5. Friction Stir Welding: By plunging a rotating tool with a pin into the steel coils, heat is generated through friction, and the softened material is stirred together to form a solid joint. Although primarily used for joining aluminum, it can also be applied to steel coils. 6. Ultrasonic Welding: This technique involves applying high-frequency vibrations to the steel coils, creating friction and heat for fusing the materials. It is commonly used for smaller steel coils and provides fast and efficient welding with minimal distortion. These methods offer distinct advantages and are suitable for specific applications. The choice of welding method depends on factors such as the type and thickness of the steel, desired strength and quality of the weld, production speed, and cost considerations.

Q: Steel coil from vertical to horizontal, what sling needs?: The sling has little effect, but it is easy to damage the surface of rolled steel.

Q: How are steel coils inspected for impact resistance?: Steel coils are typically inspected for impact resistance using various methods to ensure their durability and ability to withstand external forces. One common method is the drop test, where a steel coil is dropped from a specified height onto a hard surface. This test simulates the impact that the coil may encounter during transportation or handling. During the drop test, the coil is visually inspected for any visible signs of damage, such as dents, cracks, or deformations. Additionally, the coil may undergo further examinations, such as ultrasonic testing or magnetic particle inspection, to detect any hidden internal defects that could compromise its impact resistance. Another method used to inspect steel coils for impact resistance is the pendulum test. In this test, a pendulum with a known weight and height is swung and impacts the coil's surface. The energy absorbed by the coil during the impact is measured, and this data is used to evaluate its resistance to impact. Furthermore, steel coils may undergo laboratory tests, such as Charpy impact testing, to determine their resistance to sudden impacts. This test involves striking a notched sample of the coil with a pendulum hammer, measuring the amount of energy absorbed by the sample, and evaluating its impact strength. Overall, a combination of drop tests, visual inspections, non-destructive testing methods, pendulum tests, and laboratory tests are used to inspect steel coils for impact resistance. These inspections ensure that the coils meet the required standards and can withstand the potential challenges they may encounter during transportation, storage, and use.

Q: The steel is orangish in colour and is mostly made of copper: Steel is an alloy of iron and carbon and optionally one or more of numerous other materials. Copper is normally not used, except sometimes in small percentages. Steel is never yellow or orange in color. Reactivity of steel depends on the materials it is alloyed with. Chromium and nickel with steel make stainless steel, which is much less prone to reactive than iron. .

Q: How are steel coils used in the production of consumer goods?: Steel coils are used in the production of consumer goods by being processed and shaped into various components, such as springs, wires, or tubes, which are then used in the manufacturing of products like automobiles, appliances, furniture, and packaging materials.
