Q: I work the Copper plating line at a custom plating facility in MI.I like to use jumper cables with the jumper cable clamps to help confirm electric current is getting to my parts that I am plating. The acids in the Acid copper is constantly eating the steel and copper clamps. WIll I get a good enough current through stainless steel clamps? I use stainless steel hooks, but our maintenance man thinks that is one of the reasons why I have prblems with my parts turning out. I still think it has to do with the clamps getting eatin up. My question is Is stainless steel as good or reliable enough to run an electrical current to my parts if I am using stainless steel or is it best to use another method to try and get a better connection.Please state your sources or experience with working with electricity. I need to get honest answers and not this is my opinion. We are talking about my making a living so this is important to me so I can bring food home to my table. Thanks for all the help.: Stainless Steel Conductivity

Q: How do steel coils contribute to the HVAC industry?: Steel coils are an integral component of the HVAC (Heating, Ventilation, and Air Conditioning) industry and play a crucial role in the functioning and efficiency of HVAC systems. These coils are typically made from high-quality steel, such as stainless steel or galvanized steel, which ensures durability and resistance to corrosion. One of the main ways steel coils contribute to the HVAC industry is by facilitating heat transfer. HVAC systems use coils to transfer heat between the air and a refrigerant. In air conditioning units, for example, the evaporator coil absorbs heat from the indoor air, while the condenser coil releases heat to the outside air. The steel coils in these units provide a large surface area for efficient heat exchange, enabling the cooling or heating of the air as required. Moreover, steel coils also contribute to the overall energy efficiency of HVAC systems. By maximizing heat transfer, these coils allow HVAC systems to operate at optimal performance levels while consuming less energy. This not only helps reduce energy costs for users but also makes HVAC systems more environmentally friendly by minimizing energy consumption and greenhouse gas emissions. Steel coils in HVAC systems also contribute to the quality of indoor air. As air passes over the coils, any impurities, such as dust, dirt, or mold, can accumulate on the coil's surface. Regular maintenance and cleaning of the coils are essential to prevent the buildup of contaminants that could negatively impact air quality. Properly maintained steel coils ensure clean and healthy indoor air, which is particularly important for commercial buildings, hospitals, and other spaces where air quality is crucial. In addition to their heat transfer and energy efficiency capabilities, steel coils also provide durability and longevity to HVAC systems. Steel is a strong and resilient material that can withstand high temperatures, pressure, and environmental stressors. By using steel coils, HVAC systems can operate reliably and efficiently for extended periods, reducing the need for frequent repairs or replacements. Overall, steel coils are a vital component of the HVAC industry. They enable efficient heat transfer, improve energy efficiency, enhance indoor air quality, and provide durability to HVAC systems. Without steel coils, the performance and effectiveness of HVAC systems would be significantly compromised, making them an indispensable element of the HVAC industry.

Q: How much money do you think I could get per lb if I wanted to trade in scrap steel material?: Scrap steel is usually traded per ton. Average steel prices fluctuate on a daily basis. General prices for scrap steel are around $100 - $200 per ton. For daily scrap steel prices check the source below

Q: How are steel coils used in the production of oil and gas pipelines?: Steel coils are used in the production of oil and gas pipelines as they are formed into pipes and provide the necessary strength and durability required for transporting these resources over long distances. The coils are uncoiled and then shaped into pipes through a process called pipe forming or rolling, which allows for the creation of seamless or welded pipes depending on the specific requirements. These pipes are then further processed, such as being welded together, coated, or threaded, to ensure their suitability for the transmission of oil and gas. Overall, steel coils play a crucial role in the manufacturing of pipelines by providing the necessary raw material for their construction.

Q: Steel is a mixture of Iron Carbon . So , is steel a metal or non - metal ?: Boeing is building the new 787 dreamliner almost completely out of composites. If you take a look at an Ashby chart (Strength vs. Density) you would see that there are composites that are as strong as steel but as dense as aluminum.

Q: How are steel coils used in the production of shelving units?: Steel coils are used in the production of shelving units by being cut, shaped, and formed into the necessary components such as uprights, shelves, and brackets. These coils are unrolled and fed into machines which use different processes like stamping, bending, and welding to transform them into the desired shelving parts.

Q: I am doing a experiment on mild steel soaked in sodium chlorideanyone can enlighten me about the effect of the sodium chloride in engineering term ?The mild steel specimen which I soaked in the sodium chloride has orange rust on it: The mild steel contains a lot of Iron. The NaCl solution quickly attacks the iron content and forms rust. Over time, the solution may also cause what is called 'Chloride Cracking' of the steel. Pitting corrosion of stainless steel due to chlorides would certainly produce a rust-colored product. Passivation can be used to maintain a good corrosion resistant surface of stainless steel process vessel. There are many commercial products for this purpose. In the pharmaceutical industry, this process is often called derouging, that is to remove the buildup of iron oxides on the stainless steel process surfaces

Q: Can steel coils be used in electrical applications?: Certainly, electrical applications can make use of steel coils. In the realm of electrical circuits, steel coils often serve as magnetic cores in transformers and inductors, which are indispensable components. The steel employed in these coils typically consists of high-quality electrical steel, possessing distinct magnetic attributes, including low core losses and high permeability. These attributes empower the steel coils to efficiently transmit electrical energy between various circuit components. Furthermore, steel coils can also find utility in other electrical applications, such as the construction of electric motors and generators. Taking everything into account, steel coils are extensively employed in electrical applications due to their magnetic properties and their capacity to handle high currents and temperatures.

Q: How are steel coils inspected for weldability?: Steel coils are inspected for weldability through a series of comprehensive tests and examinations. The main objective of this inspection is to assess the quality and suitability of the steel coils for welding processes. Firstly, visual inspection is conducted to identify any visual defects or irregularities on the surface of the coils. This includes checking for surface roughness, cracks, scratches, or any other imperfections that may affect the weldability. Next, destructive testing methods such as tensile testing and impact testing are performed. Tensile testing measures the strength and ductility of the steel, ensuring it meets the required mechanical properties for welding. Impact testing evaluates the steel's resistance to brittle fracture, which is crucial in determining its weldability. Furthermore, non-destructive testing techniques such as ultrasonic testing (UT) and magnetic particle inspection (MPI) are employed to detect internal defects and discontinuities. UT uses high-frequency sound waves to identify any hidden flaws within the steel, while MPI utilizes magnetic particles to identify surface and near-surface defects. Additionally, chemical analysis is carried out to determine the steel's composition and ensure it meets the required specifications for welding. This analysis involves checking the levels of carbon, manganese, sulfur, and other elements that may affect the weldability and overall performance of the steel. Moreover, weldability testing is performed to evaluate the steel's response to welding processes. This involves conducting various welding trials using different techniques and parameters to determine the steel's behavior during welding, such as its susceptibility to cracking, distortion, or other welding-related issues. Overall, the inspection of steel coils for weldability is a multi-faceted process that combines visual, destructive, non-destructive, chemical, and weldability testing methods. By conducting these thorough inspections, manufacturers can ensure that the steel coils meet the required standards and are suitable for welding applications.
