Q: That's my question, well that and:Steel Pick + Electric Guitar = Trashed Guitar?:D: A steel pick + acoustic on nylon strings = not so good A steel pick + acoustic on steel strings = this might work A steel pick on electric guitar = this might work too I don't think you would trash the guitars, and you probably wouldn't have to worry about being electrocuted...lol... A plastic pick would be so much better. Do they even make steel picks ?

Q: I work in a steel foundry 10-12 hours a day where we melt and pour stainless steel tubes. The pour temperature for some of them is very close to the boiling point of stainless steel (about 3800 degrees) because it has to be VERY liquid for the application we use it. Anyway, it does boil a little and we breath in the vapours which I can assure you ARE indeed vapourized stainless steel (it collects and cools on everything and makes a nice shiny coating). Ok, so to the question, does breathing vapourized stainless steel all day pose a health risk such as cancer? Anyone know? I'm just curious.: I would imagine it's not good. I doubt cancer but I suppose it may be possible. Shouldn't you guys have respirator gear on? Where's OSHA when you need'em? ;)

Q: How do steel coils contribute to structural integrity in buildings?: The role of steel coils in ensuring the structural integrity of buildings cannot be overstated. They play a vital role in multiple ways. To begin with, steel coils are extensively utilized in the construction industry to manufacture essential building components like beams, columns, and trusses. These components are responsible for providing support and stability to the overall structure. Due to their exceptional tensile strength and durability, steel coils guarantee that these components can withstand heavy loads and maintain their structural integrity over an extended period. This is particularly crucial in buildings with multiple floors or large open spaces, where the structural elements need to bear substantial weight without deforming or collapsing. Moreover, steel coils are also instrumental in reinforcing concrete structures. Reinforced concrete is a widely adopted construction technique, and steel coils, in the form of reinforcement bars or mesh, are embedded within the concrete to counteract tensile forces. While concrete excels at withstanding compressive forces, it is weak in tension. By incorporating steel coils, the composite material gains the ability to resist both compression and tension, thereby enhancing its structural integrity. This reinforcement technique is particularly vital in high-rise buildings or structures subject to seismic activity, where the risk of structural failure due to bending or cracking is heightened. Another significant contribution of steel coils to structural integrity lies in their corrosion resistance properties. Steel coils are often coated with protective layers, such as zinc through galvanization or paint, to prevent corrosion caused by moisture, chemicals, or environmental factors. Corrosion weakens the structural integrity of steel, leading to degradation and potential failure. By utilizing corrosion-resistant steel coils, the lifespan of the building is prolonged, and the risk of structural damage is significantly diminished. Furthermore, steel coils offer tremendous versatility in design and construction. Their flexibility and malleability allow for the creation of complex and intricate building structures, enabling architects and engineers to push the boundaries of design while maintaining structural integrity. Steel coils can be shaped, bent, and welded into various forms, making them an ideal material for constructing innovative and aesthetically pleasing buildings. In conclusion, steel coils are indispensable in ensuring the structural integrity of buildings. Their strength, stability, durability, corrosion resistance, and design versatility make them an essential material in modern construction, guaranteeing the safety and longevity of buildings for years to come.

Q: How are steel coils used in the production of agricultural irrigation systems?: Steel coils are used in the production of agricultural irrigation systems to create the pipes and tubing that transport water to crops. These coils are formed into various designs to meet specific irrigation needs, ensuring efficient and reliable water distribution for optimal crop growth.

Q: How are steel coils used in the production of scaffolding?: Scaffolding production heavily relies on steel coils as they serve as the primary raw material for manufacturing various components of scaffolding systems. These coils, typically composed of high-quality steel, are processed through cutting, shaping, and welding operations to obtain the desired dimensions and shapes for scaffolding components, including vertical and horizontal tubes, diagonal braces, and base plates. The main structural elements of scaffolding are the tubes and pipes formed from steel coils. These elements are responsible for constructing the framework of the scaffolding, comprising vertical uprights or standards, horizontal ledgers, and transoms that connect them. By providing strength, stability, and load-bearing capacity, these components ensure the safety of workers operating at elevated heights. Furthermore, diagonal braces, an essential part of scaffolding, are manufactured from steel coils. These braces are strategically installed diagonally between the vertical standards to reinforce the scaffolding structure, adding extra support and stability to prevent swaying or collapsing. Another crucial component produced from steel coils is the base plate. These plates serve as the foundation for the scaffolding structure, offering a solid and stable base to evenly distribute weight and load. Typically positioned at the bottom of each vertical standard, they play a vital role in maintaining stability and preventing sinking or sliding. To summarize, steel coils play a fundamental role in scaffolding production. Through their transformation into tubes, pipes, braces, and base plates, they form the framework and provide the necessary strength, stability, and load-bearing capacity for safe and efficient scaffolding systems.

Q: How are steel coils inspected for camber using laser profiling?: Steel coils are inspected for camber using laser profiling, which is a non-contact measurement technique. Laser profiling involves the use of a laser beam that is emitted onto the surface of the steel coil. As the laser beam moves across the coil, it creates a profile of the coil's surface, capturing precise measurements. To inspect for camber, the laser profiling system scans the entire length and width of the coil, capturing data points at regular intervals. These data points are then analyzed to determine the deviation from a straight line, which indicates the presence of camber. During the inspection process, the laser profiling system compares the measured profile of the steel coil to a reference profile, which represents an ideal or straight surface. The deviation between the measured profile and the reference profile is calculated, and if this deviation exceeds a predetermined threshold, the coil is flagged as having camber. Laser profiling offers several advantages for inspecting steel coils for camber. Firstly, it provides a non-contact measurement, eliminating the need for physical contact with the coil and reducing the risk of damage. Additionally, laser profiling is highly accurate, capable of capturing even small deviations in the coil's surface. This ensures that camber is detected reliably, allowing for necessary corrective actions to be taken. Overall, the use of laser profiling for inspecting steel coils for camber ensures efficient and accurate detection of this defect, enabling manufacturers to maintain high-quality standards and deliver reliable products to customers.

Q: What are the different methods of forming steel coils?: There are several methods used for forming steel coils, depending on the specific requirements and applications. These methods include hot rolling, cold rolling, and continuous casting. Hot rolling is the most common method used for forming steel coils. It involves heating the steel billet or ingot to high temperatures and then passing it between a series of rollers to reduce its thickness and shape it into a coil. This process is typically performed above the recrystallization temperature of the steel, which allows for better shaping and improved mechanical properties. Cold rolling, on the other hand, is a process that is performed at or near room temperature. It involves passing the steel through a series of rollers to reduce its thickness and shape it into a coil. Cold rolling is often employed to produce steel coils with precise dimensions and excellent surface finish. It can also increase the strength and hardness of the steel. Continuous casting is another method used for forming steel coils. It involves pouring molten steel into a continuous casting machine, where it is solidified into a strand. The strand is then continuously fed into a series of rollers, which shape it into a coil. Continuous casting offers several advantages, such as improved efficiency, reduced energy consumption, and better control over the steel's composition and quality. In addition to these primary methods, there are various secondary processes involved in forming steel coils. These include pickling, annealing, and coating. Pickling removes any rust or scale from the surface of the steel, ensuring a clean and smooth finish. Annealing involves heating the steel to a specific temperature and then slowly cooling it, which helps to improve its ductility and reduce internal stresses. Coating is often applied to steel coils to provide corrosion resistance or enhance its aesthetic appeal. In summary, the different methods of forming steel coils include hot rolling, cold rolling, and continuous casting. Each method offers unique advantages and is chosen based on the specific requirements of the steel product. Additionally, secondary processes such as pickling, annealing, and coating are often employed to further enhance the quality and performance of the steel coils.

Q: I also heard Stainless holds up better againts rust, blue steel needs more care.: They have different properties. Bluing on steel is a surface treatment that helps inhibit rust, but doesn't prevent it. It will wear off with use over time, but can be redone. Stainless steel refers to a particular type of steel alloy, usually incorporating nickel and chromium, that is highly resistant to rust on its own, so doesn't need a surface treatment. Because the steel itself is what is rust resistant, that property can't wear off. All other things held equal, the carbon steel that bluing is typically applied to tends to be slightly more rigid and brittle than stainless steel. It may hold an edge better than stainless. In most applications, those differences are small enough not to matter for practical purposes. For example, both knives and guns are made with blued steel and stainless steel. Which a person gets is usually a matter of preference (unless you're, say, a professional restaurant chef whose knives have to hold a fine edge through constant hard use).

Q: What is the market demand for steel coils?: The market demand for steel coils is influenced by various factors such as construction, manufacturing, and infrastructure development. As steel coils are widely used in industries like automotive, construction, and appliances, the market demand for steel coils is generally high. However, it can fluctuate depending on economic conditions, industry trends, and global demand for steel products.

Q: Why is it usually scorned by the shooting community to use steel cased ammo (like Wolf)? Always hear corrosive and steel is bad for the extractor/firing pin. Hulp a simpleton out!: Here's a true life example: My Bushmaster AR15 extractor rips the lip/rim off the steel casing leaving the fired round jammed into the chamber. It takes a push rod to remove the casing. It happens pretty frequently, and I recently took half a brick of the junk and dropped it off at my local gun store on amnesty day. I've never had that issue with brass.
