Q: What is the role of steel coils in the manufacturing of bridges?: Steel coils play a crucial role in the manufacturing of bridges as they are used as the primary material for constructing the structural components of the bridge, such as beams, columns, and girders. These coils are manufactured by rolling steel into flat strips, which are then wound into large coils. The high strength and durability of steel make it an ideal choice for bridge construction, as it can withstand heavy loads, extreme weather conditions, and provide long-lasting support. The coils are processed further to fabricate the required bridge components, ensuring the structural integrity and stability of the bridge.

Q: What are the dimensions of steel coils used in the HVAC industry?: The dimensions of steel coils used in the HVAC industry can vary depending on the specific application and requirements of the system. However, there are standard dimensions that are commonly used. One common dimension for the width of steel coils used in HVAC systems is around 24 inches (or 2 feet). This width allows for efficient airflow and heat transfer within the system. The thickness of the steel coils can also vary, but a common range is between 0.020 inches to 0.060 inches. Thicker coils may be used for heavy-duty applications or systems that require higher performance, while thinner coils are suitable for lighter-duty or more cost-effective systems. As for the length of the coils, it can also vary depending on the specific needs of the HVAC system. Coils are often produced in standard lengths, such as 50 feet or 100 feet, but they can be customized to meet specific requirements. It is important to note that these dimensions are just general guidelines and can vary depending on the manufacturer, supplier, and specific HVAC system requirements. Consulting with industry professionals or manufacturers can provide more specific information on the dimensions of steel coils for a particular HVAC system.

Q: How are steel coils inspected for defects?: Steel coils are inspected for defects using various methods to ensure that the quality of the product meets the required standards. One common method is visual inspection, where trained inspectors examine the surface of the coils for any visible defects such as cracks, scratches, or dents. This is usually done by visual observation or with the assistance of magnifying tools. Another method is magnetic particle inspection, which is used to detect surface and near-surface defects such as cracks or voids. In this process, a magnetic field is applied to the steel coil, and a magnetic powder is applied to the surface. If there are any defects, the magnetic powder will be attracted to them, making them visible to the inspector. Ultrasonic testing is also commonly used to inspect steel coils for defects. In this method, high-frequency sound waves are transmitted into the coil, and the reflected waves are analyzed. Any deviations in the sound waves can indicate the presence of defects such as cracks or voids within the coil. Additionally, eddy current testing is employed to detect defects in steel coils. This method uses electromagnetic induction to generate eddy currents within the coil. Any changes in these currents caused by defects in the material are detected and analyzed by the inspector. Lastly, some steel coils may undergo destructive testing, where a sample is taken from the coil and subjected to various tests such as tension or bend testing. These tests are performed to evaluate the mechanical properties of the steel, which can indirectly indicate the presence of defects. Overall, steel coils are inspected for defects through a combination of visual inspection, magnetic particle inspection, ultrasonic testing, eddy current testing, and potentially destructive testing. These methods ensure that any defects are identified and addressed, ensuring that only high-quality steel coils are delivered to customers.

Q: who, when and where was dual phase steel invented?: Dual Phase steels refers to a distinct group of alloys which are used for automotive bodies. These were developed to give improved deep drawing (for shaping) and strength while on the road. Most of the work was started at the same time in the 1970s as a response to the oil crisis (history repeats!) with SSAB in Europe, US Steel and British Steel leading the way. There are many variants of the dual phase alloys prefered by each of the auto manufacturers. The work on these steels led the way for TRIP (transformation induced plasticity) steels, rephosphorised steels and HSLA (high strength low alloy) steels. There is a distinction between these steels and duplex steels which typically refer to austenitic/ferrtic stainless steels. Also be aware that everyday low carbon steels with 0.1%-0.6% carbon will have a ferritic/pearlitic structure but are not considered to be dual phase So to summarise: Who - major steel companies worldwide When - from about 1973 onwards (up to around 1977 when the developments went in other directions) Where - Europe, USA and Japan (but I'm not sure who it was in Japan doing the work)

Q: is it much difference between 1095 and 1080,,,1065,,,1060 or even 1045 steel?please help and thanks!: The guy below me obviously has no idea WTF he's talking about. It does NOT have anything to do with the edge angle at which the blade is sharpened. It does NOT have to do with heat treating. Both of these things are important, but they won't determine the type of steel. I'll try to help. 1095 is one of the best performing steels, against carbon steel or stainless steel, in the world. It's incredibly hard, holds its edge well and comes to a beautiful edge when sharpened correctly. As you know though, carbon steels need to be properly maintained to avoid rust/corrosion. Out of the steels you listed I'll give a brief summary of each steel... -1095 (Great all around steel, but is brittle by comparison to the others. This doesn't mean it will chip easily, but the other steels can take more of a beating. That being said, this is going to take a nicer edge, and hold it longer.) -1080 (A little bit more flexible and less liable to chip than 1095. A good compromise between edge retention/quality and ruggedness. -1065 (Commonly used in machetes and other heavy duty bush tools. Takes a decent utility edge and is highly unlikely to chip) -1060 1045 (Both extremely flexible and soft in comparison to 1095. Unlikely to chip, but it takes a crude edge. This edge will cut, but not like 1095 will.) Go with 1095. My favorite knife I own is in 1095 and serves me well everytime I head off into the woods. Keep some Rem-Oil on that bad boy though.

Q: My uncle got me some new 'Nam style jungle boots at the px at Fort Worth JSB, and he told me that back in Vietnam, they used to issue guys steel sole boots, that had a sole reinforced with a steel plate, as punji stick d-fence. Is this true, it sounds logical, but I can't figure out how a steel plate in the sole would work. My uncle is kind of a BS'er, plus he wasn't even in Vietnam, much less the Infantry, much less combat, but he was in USAF at the time.: The issue of steel soled boots in Vietnam did actually happen. The steel plate is in the mid-sole, to prevent punji sticks (or other sharp objects) from penetrating the boot if you stepped down on them. These bamboo or metal spikes - often coated with human excrement - were placed in shallow (camouflaged) pits dug in the ground or sometimes under water at places where you'd ford a stream. Quite apart from the physical injury from stepping on one, there was a high risk of serious infection from what they were coated with. Originally the steel plate was issued as an insole to go inside but that give the soldiers blisters, so later the boots were manufactured with it as part of the sole. Steel toe-cap boots containing a mid-sole plate are sold today for use by builders and construction workers who have a similar risk of stepping on nails, screws, glass, etc.

Q: Corten steel tends to overheat in hot environments? (for example copper heats up under the sun): Weathering steel, best-known under the trademark COR-TEN steel and sometimes written without the hyphen as Corten steel, is a group of steel alloys which were developed to obviate the need for painting, and form a stable rust-like appearance if exposed to the weather for several years. Overheating ? It's not possible for a metal to get hotter than it's environment unless there is a source of radiation. The sun shining on a metal will heat up a bit, as will any material, but the amount is small and depends on the surface reflectivity. Define what you mean by overheating. .
