Q:I'm buying a new set of steel plugs.I've heard things about streched ears and cold weather not being to good. do you think it would be bad to be wearing steal plugs?
It depends on the person. Sometimes cold weather makes stretched ears feel tight, like tighter against plugs. I never felt this, and my friends never have either(at least they say they haven't). Go ahead and wear them, but if you feel any discomfort, just change them out.
There are several different coil leveling machine configurations that are commonly used for steel coils. These configurations vary based on the specific requirements of the steel coils being processed. One common configuration is the four-high leveling machine. This machine consists of four leveling rolls arranged in a stack. The steel coil passes through these rolls, which apply pressure to flatten and level the material. The four-high configuration is often used for thicker and heavier steel coils, as it provides a higher level of pressure and control during the leveling process. Another configuration is the six-high leveling machine. This machine has six leveling rolls arranged in two stacks of three rolls each. The steel coil passes through the first stack, where the initial leveling is performed, and then through the second stack for further refinement. The six-high configuration is often used for thinner steel coils, as it allows for a more precise and gentle leveling process. In addition to these configurations, there are also combination leveling machines available. These machines combine leveling with other processes, such as slitting or shearing, to provide a more comprehensive solution for steel coil processing. Combination machines are often used in applications where multiple steps are required to achieve the desired final product. Overall, the choice of coil leveling machine configuration depends on factors such as the thickness and weight of the steel coil, as well as the desired level of precision and efficiency. Manufacturers and processors must carefully evaluate their specific needs and select the appropriate configuration to ensure optimal results in the steel coil leveling process.
Steel coils are essential in energy-efficient transportation due to their lightweight yet strong nature. The use of steel coils in vehicles, such as cars and trucks, reduces the overall weight of the vehicle, enhancing fuel efficiency and reducing carbon emissions. Additionally, steel coils are often used in rail transportation, where their durability and strength contribute to the energy efficiency of trains by allowing for higher speeds and improved load carrying capacity.
Q:My neighbor who has an older model mustang installed a steel clutch in it and has blown 4 transmissions as a result.Can any mechanic explain why a steel clutch would kill transmissions? What other modifications would the car need in order to prevent this?
i own a repair shop,and i can tell you ,part of his problem is probably the installation part of it,and secondly what he,s using is made for racing,not street driving that's probably the second part of it,i have built a few of those transmissions,and they usually don't wipe the transmission out when they go,id say a lot of his,is in the work ,or who did it there's no way to prevent this,other than to build the transmission,and use it for what it was intended to be used for,good luck,i hope this help,s.
Q:Correct me if I am wrong, but steel is an alloy between iron and carbon. Does the carbon in the steel stops the iron from rusting or corroding? Also what is the difference between mild steel and stainless steel?
Mild steel is an alloy. It is the most common form of steel. Mild steel (a so-called carbon steel) is a general term for a range of low carbon (a maximum of about 0.3%) steels that have good strength and can be bent, worked or can be welded into an endless variety of shapes for uses from vehicles (like cars and ships) to building materials. The carbon does not stop the material rusting or corroding. In addition to iron, carbon, and chromium, modern stainless steel may also contain other elements, such as nickel, niobium, molybdenum, and titanium. Nickel, molybdenum, niobium, and chromium enhance the corrosion resistance of stainless steel. It is the addition of a minimum of 12% chromium to the steel that makes it resist rust, or stain 'less' than other types of steel. The chromium in the steel combines with oxygen in the atmosphere to form a thin, invisible layer of chrome-containing oxide, called the passive film. The sizes of chromium atoms and their oxides are similar, so they pack neatly together on the surface of the metal, forming a stable layer only a few atoms thick. If the metal is cut or scratched and the passive film is disrupted, more oxide will quickly form and recover the exposed surface, protecting it from oxidative corrosion.
Q:For example, (and this is weird) if I were wearing a steel collar and I needed some way to remove it, with limited supplies.Force is difficult because it would be around my neck.Chemical cominations are great- but they have to use VERY common products. And I'm not sure what to use.Other ideas?
Your best bet would be a grinding wheel attached to a small electric motor. Even if you slipped, your skin is too soft to be cut by the dull wheel. Steel, however, is easily cut. But perhaps you don't have access to electricity or pressurized air to run such a tool. In that case, a simple file would work well, though you'd be somewhat more likely to injure yourself. If you had no tools, but access to whatever chemicals you wanted, you could try a weak acid. This would take a long time, and require constant scrubbing to bring fresh acid into the pits in the metal, but it would eventually eat through the collar.

Steel coils are typically used as a primary raw material in the production of metal storage systems. These coils are unrolled and processed through various machines and equipment to form different components such as shelves, frames, and supports. The steel coils are cut, shaped, welded, and coated to ensure durability and strength. Additionally, the coils can also be used to create interlocking panels or sheets that form the walls and roofs of the storage systems. Overall, steel coils play a crucial role in the manufacturing process, providing the necessary material for the construction and assembly of metal storage systems.
Q:Is cold steel actually steel? Does it hurt? Why is it used in training? First one to goodly answer those questions gets 10 points.
Cold steel was an expression originally used to signify a sword. From feeling the cold of the blade as it entered the body.
Q:So here's the deal:I recently bought McCann's Instant Steel-Cut Oatmeal, and I'm wondering about any possible nutritional differences between the instant and regular stove-top. In case you haven't seen it, instant steel-cut comes in individual packets and is cooked only by adding boiling water, the same as instant rolled oatmeal (i.e. Quaker).When I asked about instant vs. stove-top rolled oats, my doctor said there are no significant nutritional differences, but since the main health appeal of steel-cut is the coarse grain, it doesn't seem possible for the finer ground instant to be as nutritious.I can't find much info about this, so any help is appreciated!
The rationale for consuming steel cut oats rather than rolled oats (beyond the fact that the former taste really good) is the lower glycemic index. It is my understanding that in the rolled oat category, it is better to eat the long-cooking variety rather the instant for the improved fiber load and lower glycemic index. While I do not understand exactly how instant steel cut oats are processed and how much the glycemic index is affected by processing, it is safe to assume that the old unprocessed steel cut oats are still best. I always prepare 4-6 servings of the steel cut oats at one time and warm up a serving when needed to avoid having to wait 30 minutes to cook them. My rule of thumb: the less processing for any food product, the better it is for me.
