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.: I can only guess. I can't even tell if you are plating some other metal with copper OR if you are plating copper with some other metal. you state that you use the copper clamps only to confirm the current, but I don't see how that works. I suspect that the plating current actually goes through these clamps, so conductivity is very important. But, the conductivity of SS is about 1/5th that of copper, so that will definitely have an effect, and not a good one. .

Q: Where do I need hot galvanized steel coils and color coated rolls?: In industrial or coastal areas, due to the influence of sulphur dioxide or salt in the air, the corrosion rate is accelerated and the service life is affected. In the rainy season, the coating has been soaked by rain for a long time, or the temperature is too large and easy to dew. It will be corroded quickly and the service life will be reduced. A building or building made of colored coated steel plates, often with a long service life when washed by rainwater, otherwise affected by sulfur dioxide, gas, salt, and dust. Therefore, in the design, if the roof slope is greater, the more difficult to accumulate dust and other dirt, the longer the service life; for those areas or parts that are not often washed by rain water, should be regularly washed with water.

Q: What are the different types of steel coil packaging materials for export?: There are several different types of steel coil packaging materials that are commonly used for export: 1. Steel Strapping: This is one of the most common and widely used materials for packaging steel coils. Steel strapping is strong and durable, providing excellent protection during transportation. It is available in different widths and thicknesses to accommodate different coil sizes. 2. Stretch Film: Stretch film is a flexible and elastic material that is often used to wrap steel coils. It provides a tight and secure packaging, preventing the coils from shifting or falling during transit. Stretch film is also lightweight, which helps to reduce shipping costs. 3. Corrugated Cardboard: Corrugated cardboard is often used as an outer packaging material for steel coils. It provides additional protection against external impacts and acts as a cushioning material. Corrugated cardboard is available in various strengths and sizes to suit different coil dimensions. 4. Wooden Crates: Wooden crates are a popular choice for packing larger steel coils. They provide a sturdy and robust packaging solution, offering excellent protection against impacts, moisture, and other environmental factors. Wooden crates can be customized to fit specific coil sizes and are often used for heavy-duty or long-distance shipments. 5. Plastic Strapping: Plastic strapping is an alternative to steel strapping, especially for lighter coils. It is lightweight, easy to handle, and resistant to rust and corrosion. Plastic strapping is available in different colors, allowing for easy identification and sorting. 6. VCI (Volatile Corrosion Inhibitor) Packaging: VCI packaging materials are used to protect steel coils from corrosion during export. These materials release a vapor that forms a protective layer on the surface of the coils, preventing rust and corrosion even in high humidity or harsh environments. It is important to consider the size, weight, and specific requirements of the steel coils when choosing the appropriate packaging material for export. Additionally, compliance with international shipping regulations and standards should be ensured to guarantee a safe and efficient transportation process.

Q: I'm trying to buy a Survival,tactical knife but don't know what steel is better: This Site Might Help You. RE: Whats better chrome vanadium steel or carbon stainless steel? I'm trying to buy a Survival,tactical knife but don't know what steel is better

Q: How are steel coils inspected for surface defects after processing?: Steel coils are inspected for surface defects after processing through visual inspection, magnetic particle inspection, or ultrasonic testing. Visual inspection involves examining the surface for any visible defects such as scratches, dents, or corrosion. Magnetic particle inspection uses magnetic fields and iron particles to detect surface cracks or defects that may not be visible to the naked eye. Ultrasonic testing involves using high-frequency sound waves to detect internal and surface defects in the steel coils. These inspection methods help ensure the quality and integrity of the steel coils before they are further processed or delivered to customers.

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: How are steel coils used in the manufacturing of automotive doors?: Steel coils are used in the manufacturing of automotive doors by being shaped and cut into the desired size and shape for the door panels. These coils are then formed into the appropriate curvature and attached to the door frame, providing strength, rigidity, and durability to the door structure.

Q: How are steel coils used in the production of metal roofing panels?: Steel coils are used in the production of metal roofing panels by being unrolled and fed through a rolling machine that shapes and forms the metal into the desired panel shape. This allows for efficient and precise manufacturing of metal roofing panels, which are then used for construction purposes.

Q: The knife will be large and thick. Like the Bowie knife Rambo uses in Rambo III. It doesn't need to be flexible or to hold the edge very well. But i need it to be exceptionally strong material and to stop corrosion at least decently. Is Damascus Steel good?Thank you, in advance.: Damascus steel is the poorest quality. The laminations separate under stress. Centuries ago the only way to get steel bars was to make it up by hammering wires together in a series of welds. The welds usually were porous and the steel would fail. The pattern of the welds is attractive to some people. An old file has good hard steel and wiill make up into a knife if it is annealed to make it easier to shape and cut. The hardness can be restored by tempering. Treating with oil is the cure to prevent rust.

Q: A 100 kg solid steel ball with a radius of 5 m is being spun on ice with an angular velocity of 5 rev/s pointed into the ice (clockwise rotation when viewed from above).A student shoots a 10 kg marble at the steel ball. The marble hits the ball along its side as shown with an initial velocity of 5 m/s to the left. If, right after the collision, the final velocity of the marble is 2.5 m/s to the left, what is the angular velocity of the steel ball after the collision?: You need to do conservation of angular momentum about the steel ball's axis. Angular momentum = I.ω The steel ball's initial ω = 5 rev/s = 5*2pi rad/s = 31.4 rad/s The steel ball's moment of inertia I = (2/5)*m*r^2 = 40*25 kg.m^2 = 1000 kg.m^2 The marble's initial ω = v / r where r is the perpendicular distance from the steel ball's axis You need to look at the diagram for this. The marble's I about the steel ball's axis is I = m*r^2 where r is the same as above. (marble is treated as a point mass). Then work out the total initial ang. momentum = final ang. momentum and solve for ω...
