Hot rolling is a mill process which involves rolling the steel at a high temperature (typically at a temperature

over 1700° F), which is above the steel’s recrystallization temperature. When steel is above the recrystallization

temperature, it can be shaped and formed easily, and the steel can be made in much larger sizes. Hot rolled steel

is typically cheaper than cold rolled steel due to the fact that it is often manufactured without any delays in the

process, and therefore the reheating of the steel is not required (as it is with cold rolled). When the steel cools

off it will shrink slightly thus giving less control on the size and shape of the finished product when compared to

cold rolled.

 

This makes hot rolled steel a good choice for the manufacturing of structural components, such as I beams or

simple cross sections, such as rail tracks. It is also used to produce sheet metal.

Q:What are the different types of surface treatments for steel coils?
There are several different types of surface treatments available for steel coils, each designed to enhance the appearance, protect against corrosion, and improve the overall durability of the steel. Some of the commonly used surface treatments for steel coils include: 1. Hot-dip galvanizing: This process involves immersing the steel coils in a bath of molten zinc, which forms a protective layer on the surface. Hot-dip galvanizing provides excellent corrosion resistance and can withstand harsh environments. 2. Electro-galvanizing: In this method, a thin layer of zinc is electroplated onto the surface of the steel coils. Electro-galvanizing offers good corrosion resistance and improves the aesthetics of the steel. 3. Organic coating: Steel coils can be coated with organic materials such as paints, lacquers, or polymer films. These coatings provide protection against corrosion, abrasion, and UV radiation, while also offering a wide range of color options. 4. Phosphating: Phosphating is a chemical treatment that converts the steel surface into a layer of phosphate crystals. This treatment enhances the adhesion of subsequent coatings and improves the corrosion resistance of the steel. 5. Chromating: Also known as passivation, chromating involves the application of a chromate conversion coating onto the steel surface. This treatment enhances the corrosion resistance and provides a decorative finish. 6. Oiling: Oiling is a simple surface treatment that involves applying a thin layer of oil onto the steel coils. This treatment helps prevent corrosion during storage and transportation and can be easily removed before further processing. 7. Pickling: Pickling is a process where the steel coils are immersed in an acid solution to remove impurities and scale from the surface. This treatment improves the surface finish and prepares the steel for subsequent processing or coatings. 8. Tin plating: Steel coils can be coated with a layer of tin through electroplating. Tin plating provides excellent corrosion resistance, solderability, and aesthetic appeal. These are just a few of the many surface treatments available for steel coils. The choice of treatment depends on the specific requirements of the application, including the desired appearance, corrosion resistance, and environmental conditions the steel will be exposed to.
Q:I was wondering if steel cases can be loaded to the same pressure as brass cases. Are the cartridges that commonly feature steel cases like the Russian 5.45x39, 7.62x39 and 7.62x54R loaded to a lower pressure than their C.I.P. MAPs (380 MPa, 355 MPa, 390 MPa --gt; 51,488 psi to 56,564 psi)? There must be a reason why most NATO armies use brass cases...
The ammo loaded in steel casing has a tendency to be loaded at lower pressures, for some reason. Most if not all of the steel case is of foreign manufacture. No reason steel can't be loaded to same pressures to that of brass, would probably seal better. Most of the calibers you describe in steel cases go in weapons with loose tolerances, like the AK. Lot of times, the steel won't seal in the chamber, creating blow by, putting crud in the chamber. This condition makes it hard to feed, chamber, and extract in a tight dimension chamber that is present in NATO weapons. AK's, due to more generous tolerances, won't be sensitive to this.. Weapons from NATO are of more tightly toleranced chambers like the AR, HK, Barret, etc. where brass is more reliable in sealing, and minimizes the blow by and keeps things clean, or at least more clean than a steel case that may not seal.
Q:What are the common surface finishes for steel coils?
There are several common surface finishes for steel coils, depending on the specific requirements and applications. Some of the most common surface finishes for steel coils include: 1. Hot-dip galvanized: This is a process where the steel coil is immersed in a bath of molten zinc, coating the surface with a protective layer. Hot-dip galvanizing provides excellent corrosion resistance and is commonly used in outdoor applications. 2. Electro-galvanized: In this process, a thin layer of zinc is electroplated onto the surface of the steel coil. Electro-galvanizing provides good corrosion resistance and a smooth finish, making it suitable for various applications, including automotive parts and appliances. 3. Galvannealed: Galvannealed steel coils are coated with a zinc-iron alloy by passing them through a high-temperature annealing process. This finish offers improved paint adhesion and excellent resistance to corrosion, making it suitable for manufacturing automotive parts and construction materials. 4. Tinplate: Tinplating involves coating the steel coil with a thin layer of tin, providing excellent corrosion resistance and a bright, shiny appearance. Tinplate is commonly used for packaging materials and cans. 5. Pre-painted: Pre-painted steel coils have a layer of paint applied to the surface, providing both corrosion resistance and an aesthetically pleasing finish. This finish is often used for building materials, such as roofing and siding. 6. Cold-rolled: Cold-rolled steel coils undergo a process where they are rolled at room temperature, resulting in a smooth, clean surface. Cold-rolled coils are typically used in applications where a high-quality surface finish is required, such as automotive parts and appliances. These are just a few of the common surface finishes for steel coils. The choice of finish depends on the desired properties, such as corrosion resistance, appearance, and specific application requirements.

I advise you not to as it will damage your guitar :) they do sound way better but that's what an acoustics for
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:How are steel coils used in the manufacturing of industrial valves?
Steel coils are used in the manufacturing of industrial valves as they provide the necessary raw material for creating valve bodies, stems, and other components. The coils are shaped, cut, and formed into different valve parts, ensuring strength and durability. These steel components are then assembled, welded, and machined to create fully functional industrial valves used in various applications such as oil and gas, chemical processing, and water treatment industries.
Q:How are steel coils protected against fire and heat?
To ensure the safety of steel coils, various methods are used to protect them from fire and heat. One effective way is by applying a fire-resistant coating, which acts as a barrier between the steel surface and the heat source. This coating prevents direct contact and reduces the chances of ignition or damage. Aside from coatings, steel coils can also be stored in fire-resistant warehouses or storage facilities. These structures are built with fire-resistant materials like concrete or steel and equipped with fire suppression systems such as sprinklers or fire extinguishers. These measures help contain and suppress any potential fire, effectively limiting its spread and safeguarding the steel coils. Furthermore, facilities that handle steel coils often implement fire safety protocols and procedures. These may include regular fire drills, training programs for employees on fire prevention and response, and the installation of fire safety equipment like fire alarms and fire hoses. These measures ensure that any fire incidents can be quickly detected and addressed, minimizing the risk to the steel coils. Overall, protecting steel coils against fire and heat involves a combination of fire-resistant coatings, proper storage in fire-resistant structures, and the implementation of fire safety protocols. These measures work together to mitigate the risk of fire and heat-related damage, ensuring the integrity and safety of the steel coils.
Q:what is the difference between stainless steel 304 (AISI 304) and stainless steel 310 (AISI 310) COR-TEN A
Weathering steel will rust, but the rust will be adherant and not flake off and be replaced by new rust. Therefore once it rusts it will pretty much stop rusting any more. One (severe) down side is that anything around it will be streaked with rust stains and it will look awful. Some bozo with the Texas Department of Transportation designed a number of freeway interchange overpasses here in Houston using Cor-Ten steel and all of the concrete supports are streaked with red rust stains and it looks like hell. Cameron built an office building here in Houston with a Cor-Ten facade and it is streaked with rust too. They should have gone ahead and spent the money and painted them, but they didn't.
