Q:I am doing an assignment for my materials class, im not asking for the answer but just some help. I have the assignment finished and handed in but the teacher gave it back with one comment, he asked me to explain the grain growth in steel during hydraulic press bending. Im completely stuck, please help. Thanks.: Well, I can't answer the question for you because, if the press bending is done cold, the grains will not grow (at least not with normal steel alloys). One wonderful thing about metallurgy is that the real answer is it depends because there are all sorts of weird and unexpected things that can happen. Cold work (which is what press bending is unless it is done hot or the amount of deformation is extraordinary high and fast so the metal heats up a lot locally) adds stored energy (strain energy) which provides one of the driving forces for recrystallization. Recrystallization is not a yes/no process, it is a process that happens as a function of time and temperature. Recrysallization of a cold worked structure will refine the grain size if done properly but the final stage of recrystallization is grain growth and you can end up with a larger grain size than you started with. The other thing that can affect grain structure is the deformation itself. There are all sorts of transformations that can happen due to the deformation process (twinning/martensitic is one) but, again, these don't usually qualify as grain growth. It may be that the question was incomplete, maybe the question is how does the press bending affect the final grain size after a subsequent anneal? The metallurgy of steels is fascinating because there are so many different microstructures that can be produced, hundreds (or thousand) different alloys, equilibrium and non-equilibrium phases based on composition and thermo-mechanical processing. Hope this helps

Q:What processes and materials are used in the production of chrome steel: well, save up some more $$. I wouldnt feel safe on a $120 mountain bike. My advice would be to invest in something that's a little more money. Also, why do you want a steel frame? Aluminum frames today are made from 7005 alloy, and stack up very well compared to the durability of steel. Plus, they wiegh alot less. Nowadays, youll only find steel on a cheap walmart bike, ir a top notch downhill bike made for extream offf road conditions.

Q:What are the different methods of coil rewinding for steel coils?: There are several different methods of coil rewinding for steel coils, including manual rewinding, semi-automatic rewinding, and fully automatic rewinding. In manual rewinding, the coils are rewound by hand using a winding machine or tool. Semi-automatic rewinding involves the use of a machine that assists with the rewinding process, but still requires some manual intervention. Fully automatic rewinding, on the other hand, involves the use of advanced machinery that can automatically rewind the steel coils without any manual intervention. These different methods offer varying levels of efficiency, speed, and precision in the coil rewinding process.

Q:What are the different types of steel coil edges?: Various steel coil edges exist, each possessing unique characteristics and applications. 1. Mill Edge: The most prevalent type, it is obtained by cutting the coil at the mill without undergoing any further processing or treatment. Mill edge coils have a natural, slightly rounded edge, making them suitable for a wide array of applications. 2. Slit Edge: Slit edge coils are created by cutting the coil across its width using a slitting machine. This results in a straight and smooth edge, making them ideal for precise measurements needed in automotive parts or electrical components. 3. Deburred Edge: Deburred edge coils have undergone an additional process to eliminate any burrs or sharp edges that may exist after slitting. This ensures safer handling and reduces the risk of damage during fabrication or installation. Deburred edge coils are commonly used in the construction industry, particularly for structural steel components. 4. Rounded Edge: As the name implies, rounded edge coils possess a curved edge profile achieved through a specific rolling process. This creates a smooth and curved edge, making them often utilized in applications prioritizing safety, such as the manufacturing of household appliances or kitchen equipment. 5. Sheared Edge: Sheared edge coils are produced by cutting the coil using shearing blades, resulting in a straight edge with a slight burr. While sheared edge coils may have a rougher finish compared to other edge types, they are still frequently used in applications that do not require a high level of precision, like general fabrication or shelving. In summary, the choice of steel coil edge depends on specific application requirements, including factors such as measurement precision, safety considerations, and aesthetic preferences.

Q:They both sell the same thingIf prices are to high companies won't by the steelIf prices are to low then the steel company won't earn enoughWhy are some steel companies more successful than others: Steel is a global commodity. There is some variety in product (flat rolled, tubing, etc), but basically the same product worldwide. Cost to the customer includes shipping of a very heavy product. Inputs are also heavy and costly to ship. Inputs: - Coal - Iron Ore. Some firms have the ability to recycle old steel, a competitive advantage. - Energy (very energy intensive industry) - Labor - Machinery. A new blast furnace is more efficient than 50 years old. So the most profitable steel firms have some of these characteristics: - Proximity to raw materials - Proximity to customers - Access to cheaper means of transportation; rail and sea - Newer machinery - Cheaper labor force - Reasonable cost for electricity and fuel for furnaces

Q:What are the different types of steel coil edge condition options?: There are several different types of steel coil edge condition options available, each with its own unique characteristics and advantages. Some of the most common types include: 1. Mill Edge: This is the most basic and common type of steel coil edge condition. It is produced during the hot rolling process and is characterized by a naturally rough and uneven edge. Mill edge coils are typically used for applications where the edge quality is not critical, such as in general fabrication. 2. Slit Edge: Slit edge coils are created by cutting the edges of the steel coil using a slitting machine. This process produces a smoother and more uniform edge compared to mill edge coils. Slit edge coils are often preferred for applications that require a higher level of precision, such as in automotive or electrical industries. 3. Trim Edge: Trim edge coils are similar to slit edge coils but with an additional trimming process to remove any defects or imperfections from the edges. This results in an even smoother and cleaner edge, making trim edge coils ideal for applications where appearance and aesthetic quality are important, such as in architectural or decorative purposes. 4. Deburred Edge: Deburred edge coils undergo a deburring process to remove any sharp or burr-like edges. This is done to ensure safety and prevent injury during handling or processing of the coils. Deburred edge coils are commonly used in industries where worker safety is a priority, such as in construction or manufacturing. 5. Rounded Edge: Rounded edge coils have their edges rounded off to eliminate any sharp corners or edges. This type of edge condition is often used in applications where the coils will come into contact with delicate materials or surfaces, as it helps to prevent scratching or damage. It is important to note that the choice of steel coil edge condition will depend on the specific requirements of the application and the desired outcome. Each type of edge condition offers its own unique benefits, and it is crucial to consider factors such as precision, appearance, safety, and functionality when selecting the appropriate option.

Q:How are steel coils protected against bending and deformation?: Steel coils are protected against bending and deformation through various measures. One common method is the use of protective packaging materials such as wooden crates or metal skids, which provide stability and support to prevent any bending or deformation during transportation or storage. Additionally, steel coils are often secured tightly using steel or plastic bands to maintain their shape and prevent any shifting or movement. These bands are strategically placed at regular intervals along the length and width of the coils to ensure even distribution of pressure and minimize the risk of bending or deformation. Moreover, steel coils can be further protected by placing them on a flat and level surface during storage or transportation. This helps to distribute the weight evenly and reduce the chances of any bending or deformation due to uneven pressure. In some cases, steel coils may also be coated with anti-corrosion agents to protect against moisture and rust, which can weaken the structure of the coils and lead to bending or deformation over time. Overall, a combination of proper packaging, secure fastening, and careful handling is essential to protect steel coils against bending and deformation, ensuring their structural integrity and quality.

Q:How are steel coils used in the manufacturing of fuel systems?: Steel coils are commonly used in the manufacturing of fuel systems to create various components such as fuel tanks, pipes, and fittings.
