Some steel containers are made by deforming the steel by extruding, forging, spin forming, drawing, ironing, etc. Some steel containers are made by machining. You should be able to find plenty of references if you search for these terms. good luck

Q:How are steel coils used in the production of steel connectors?: Steel coils are used in the production of steel connectors as they are formed into specific shapes and sizes, such as plates or bars, which are then cut, bent, and welded to create the connectors. The coils provide a continuous and easily manageable supply of steel material, allowing for efficient and precise manufacturing processes.

Q:What are the challenges in coil slitting?: Coil slitting, also known as coil cutting, involves the process of cutting large metal coils into narrower strips. However, there are several challenges associated with this process. One challenge is maintaining precision during slitting, as any deviation can result in uneven strip widths or poor edge quality. Another challenge is managing the tension of the coil throughout the slitting process to prevent material distortion or breakage. Additionally, handling and transporting the slit coils can be challenging due to their length and weight. Overall, ensuring accuracy, maintaining proper tension, and effectively handling the slit coils are some of the key challenges faced in coil slitting.

Q:I need new sprockets on my GSX-R1, I've heard that alumnium sprockets wear out twice as fast as steel and the difference is not noticable: The solution to your problem lies in what the purpose is of going up three teeth in the back... Are you hoping to gain more low end power and thus be able to race from 0-60 faster? If thats the case, Id go with aluminum and a 520 conversion on the chain. You WILL notice the difference in how fast the bike builds steam, because it will be easier for the engine to rotate the rear wheel having a lighter chain and sprocket set. Of course, this will wear out faster than steel - but the real question is, are you interested in going faster, or saving money? Speed aint cheap. Either pay for it, or stick with steel. Be careful going up three teeth on the rear without getting a new chain as well - your current chain may not have enough slack left in it...

Q:I am in the market for a good hunting knife under $100. I am primarily looking for a knife that will keep it's edge. What type of steel should I be looking for?: Get a Kershaw hunting knife. Kershaw uses only good quality knife steel and they have plenty of hunting knives under $100.

Q:How are steel coils used in the production of aerospace components?: Steel coils are used in the production of aerospace components in a variety of ways. One common application is in the manufacturing of structural parts, such as frames, beams, and brackets. Steel coils are often processed into flat sheets or strips, which are then cut and formed into the desired shape for these components. The strength and durability of steel make it an ideal material for these critical parts that need to withstand extreme forces and conditions. Additionally, steel coils are used in the production of engine components, such as turbine blades and combustion chambers. These components require materials with high temperature resistance and excellent mechanical properties. Steel coils are processed and shaped into intricate forms to create these vital engine parts, ensuring efficient and reliable operation. Furthermore, steel coils are used in the production of fasteners, such as bolts, nuts, and screws, which are essential for assembling various aerospace components. The high strength and corrosion resistance of steel make it a preferred choice for these fasteners, as they need to withstand the extreme forces and environments experienced during flight.

Q:Is it possible that stainless steel watches get rust. Any experience? Thanks.: Under certain conditions, even stainless steel will rust. They include: Exposure to some noble metals (copper/silver) in a corrosive atmosphere - and why stainless must be separated from silver or silver plate in a dishwasher. Stainless steel will pit if touching silver as many DW detergents are rich in chlorine. Under some conditions, and depending on your skin chemistry, if you wear a copper bracelet on the same arm as the watch, the surface of the watch will pit. If you commonly are exposed to some kinds of welding fluxes, if you are exposed to water with high salt concentration and you do not rinse off the watch after exposure, that can pit the surface. Stainless Steel is no more than corrosion-resistant, not corrosion-proof. Most of the time under most conditions, it is fine. But not all of the time under every condition. As it happens, what affects SS the most is any kind of electrolysis due to galvanic action involving halogen salts.

Q:How do steel coils contribute to the manufacturing of HVAC systems?: The manufacturing of HVAC systems heavily relies on steel coils, which have a critical role. These coils typically consist of high-quality steel, known for its exceptional strength, durability, and resistance to heat. Heat exchangers are one of the primary applications of steel coils in HVAC systems. These exchangers play a vital role in transferring heat between different mediums, usually air and a refrigerant. In HVAC systems, steel coils are employed in both the evaporator and condenser coils. The evaporator coil absorbs heat from the indoor air, while the condenser coil releases heat to the external environment. These coils are designed with numerous coiled tubes connected by fins. The use of steel in their construction ensures their ability to withstand high pressure and resist corrosion, guaranteeing the long-term reliability and efficiency of the HVAC system. Steel coils also contribute to the overall structural integrity of HVAC systems. They are commonly utilized in the fabrication of ductwork, responsible for distributing conditioned air throughout a building. The strength and rigidity of steel coils enable the ductwork to maintain its shape and structural integrity under various conditions, including high air pressure and temperature fluctuations. Additionally, steel coils are frequently involved in the fabrication of HVAC system cabinets and enclosures. These cabinets house several system components, including compressors, fans, and control panels. The robustness of steel coils ensures that the cabinets can withstand external forces, protect the internal components, and provide a secure housing for the entire HVAC system. To summarize, steel coils are crucial components in the manufacturing of HVAC systems. Their strength, durability, and heat resistance make them ideal for applications such as heat exchangers, ductwork, cabinets, and enclosures. By incorporating steel coils, HVAC manufacturers can produce systems that efficiently regulate temperature, enhance indoor air quality, and provide comfort in various residential, commercial, and industrial settings.

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 of the steel is almost tertiary to many other considerations, except that there are certain elements and percentages of elements which tend to affect the crystaline structure in the steel. The most basic question is whether the crystaline arrangement of atoms in the steel is martensitic or austenitic, and many factors influence that. In general, martensitic structure is magnetic and austenitic structure doesn't respond much to magnetic fields, but there are varying degrees of martensitic and austenitic -- there is never a pure state. Read the articles at bottom.

Q:How are steel coils processed for edge trimming or slitting during processing?: Steel coils are processed for edge trimming or slitting during processing by utilizing specialized machinery. The coils are unwound and fed into the machine, where the edges are trimmed off to achieve the desired width. For slitting, the coil is passed through multiple sets of circular blades that cut it into narrower strips. This process ensures precise dimensions and smooth edges, making the steel coils ready for further applications.
