Specification
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.

- Various industries utilize a range of steel coil finishing equipment to ensure that steel coils are properly prepared and finished according to the desired specifications. Some commonly used equipment includes: 1. Slitting lines, which cut large steel coils into narrower strips using multiple slitting knives at high speeds. These are commonly used in automotive, construction, and packaging industries. 2. Leveling lines, which flatten and straighten steel coils with uneven surfaces or irregularities using leveling rolls and tension control systems. These are commonly used in the manufacturing of appliances, furniture, and metal roofing. 3. Recoiling lines, which rewind steel coils into smaller coils of specific diameter and weight by carefully winding them around a mandrel. These are commonly used in electrical, HVAC, and steel distribution industries. 4. Cut-to-length lines, which cut steel coils into specific lengths as per customer requirements using precision measuring systems and hydraulic shears. These are commonly used in manufacturing, construction, and fabrication industries. 5. Coating lines, which apply protective coatings or finishes on steel coils to enhance corrosion resistance, durability, and appearance. These lines typically consist of cleaning and pre-treatment sections, followed by coating application sections. They are commonly used in automotive, appliances, and construction industries. These examples represent just a few of the available types of steel coil finishing equipment. Each type serves a specific purpose and plays a crucial role in the manufacturing and processing of steel coils for various applications.
- Q: I noticed a friend's appliances are not magnetic, and mine are. Both are stainless steel. Are there two types of stainless steel or something? Thanks
- There are many types of stainless steel. Some are magnetic and some are non-magnetic. The magnetic properties of stainless steel are very dependent on the elements added into the alloy, and specifically the addition of nickel can change the structure from magnetic to non-magnetic. Poor heat treatment or high heat input welding of normal or high carbon austenitic stainless steels will cause sensitization, ie formation of chromium carbides. The formation of carbides not only reduces the corrosion resistance of the stainless steel but also tends to form martensite around the carbide. This martensite is magnetic and the more severe the sensitisation, the stronger are the magnetic properties. When nickel is added, for instance, the austenite structure of iron is stabilized. This crystal structure makes such steels non-magnetic and less brittle at low temperatures. Martensitic stainless steels are magnetic. *Wrought, austenitic stainless steels, such as 304 and 316, are generally regarded as non-magnetic in the annealed condition, ie they are not attracted significantly by a magnet. However, if they are cold worked they will be attracted to a permanent magnet. The change occurs because the cold work deformation induces a transformation of the microstructure from austenite to martensite. The effect is less marked in alloys with high concentrations of austenite stabilisers such as nickel, nitrogen and carbon. Once the martensite is formed, it may also become magnetised. *In contrast to the austenitic alloys, ferritic stainless steels such as 409 or 3Cr12/5Cr12 and martensitic stainless steels such as 420, are strongly attracted to a magnet even in the annealed state. The duplex and super-duplex stainless steels will also be strongly attracted because they contain about 50% ferrite in their microstructure. *
- Q: How are steel coils used in the manufacturing of automotive parts?
- Steel coils are used in the manufacturing of automotive parts as they are shaped and formed into various components such as body panels, chassis frames, and suspension parts. The coils are processed through a series of steps including cutting, bending, and stamping, to create the desired shape and size for each specific part. These steel components provide strength, durability, and structural integrity to the automobiles, ensuring their safety and performance on the road.
- Q: Can steel coils be recycled?
- Yes, steel coils can be recycled. Steel is a highly recyclable material, and steel coils can be melted down and reformed into new steel products without losing their quality or strength. Recycling steel coils helps to conserve natural resources, reduce energy consumption, and minimize waste.

- Q: this is for a school project due morrow can u please answerwhat are disadvantages of stainless steelplease also show were u got info ty
- Disadvantages of Stainless Steel: 1. High initial cost 2. Difficult to fabricate, or in other words, it is not as malleable as other metals, say iron, and hence if not fabricated properly, results in costly re-work. 3. Difficult to weld 4. High cost of polishing etc. i.e. adding finishing touches for the market. Also, for the record: Stainless steel does NOT rust. One of the advantages of it over other metals (steel and iron) are that it is rust-free. But of course, depending on the environment condition (E.g. long periods in a rainforest without use at all) it can rust....this is a very rare (and unfortunate) situation. ;)
- Q: What does "steel roll number" mean?
- Steel coil number is the specification of steel coil.
- Q: What are the common coil diameters available for steel coils?
- The common coil diameters available for steel coils typically range from 24 inches to 72 inches.
- Q: What are the different methods of edge camber correction for steel coils?
- There are several methods used for edge camber correction in steel coils, depending on the specific requirements and equipment available. Some of the common methods include: 1. Mechanical Edge Trimming: This method involves trimming the edges of the coil using mechanical tools such as shears or slitters. It helps to remove excess material and correct the camber. This method is often used for smaller coils or when the camber is minimal. 2. Tension Leveling: Tension leveling is a process where the coil is passed through a series of adjustable rollers under tension. The tension helps to elongate the steel and reduce the camber. This method is effective for correcting moderate camber and is commonly used for larger coils. 3. Roller Leveling: Roller leveling is similar to tension leveling, but instead of adjustable rollers, the coil is passed through a series of fixed rollers. These rollers exert pressure on the steel to flatten it and correct the edge camber. This method is often used for thicker and heavier coils. 4. Heat Straightening: Heat straightening involves applying controlled heat to the edges of the coil to soften the steel. Once the steel becomes malleable, external force is applied to straighten the edges. This method is suitable for correcting severe edge camber but requires specialized equipment and expertise. 5. Combination Methods: In some cases, a combination of different methods may be used to achieve the desired edge camber correction. For example, mechanical edge trimming may be followed by tension leveling or roller leveling to further straighten the edges. It is worth mentioning that the choice of method depends on various factors such as the severity of camber, coil dimensions, material properties, and available equipment. It is essential to evaluate these factors and consult with experts to determine the most suitable method for edge camber correction in steel coils.
- Q: How do steel coils perform in corrosive environments?
- Steel coils perform well in corrosive environments due to their inherent resistance to corrosion. The protective layer of oxide on the surface of steel, along with the addition of corrosion-resistant coatings, helps prevent the coils from rusting or corroding when exposed to moisture or chemicals. This makes steel coils ideal for various applications in corrosive environments, such as transportation, construction, and manufacturing industries.
