Q:7850kg/cu.m density is typical for all type of steel? like reibar, I- beam and so on: 90% of the steels used today are plain mild carbon steels consisting of iron with less than 1% carbon content and as such have a density of about 7750 kg/cubic meter. Some special steels which have a significant percentage of alloying elements such as chrome or manganese or other elements will have greater density bringing the steel up to about 8000 kg / cubic meter. There are a greater many factors influencing the exact density of a steel. Even for steels of exactly the same content of iron , carbon and other alloying elements, there may be a difference ( very small mind you ) in density due to work hardening. The difference in this case is due to movement of dislocations which become locked in the grain boundaries and this forms a more dense crystal structure. For this same reason, the theoretical density of steel (which does not take into account dislocations) is greater than the measured density of steel.

Q:How do steel coils compare to other materials, such as aluminum or copper?: Steel coils have several advantages over other materials like aluminum or copper. Firstly, steel is generally stronger and more durable, making it suitable for heavy-duty applications. Steel coils also have a higher melting point, which means they can withstand higher temperatures without losing their structural integrity.

Q:I was cutting a sheet of steel with an angle grinder when suddenly the rate at which the blade was cutting slowed way down. I tried a few different things, and turned off the tool and looked at the blade. It didn't look damaged, but it definitely was not cutting as quickly. I thought either I had hit a harder section of steel (is that possible? It looked pretty uniform) or the blade had lost it's abrasive quality or something. Also, before this happened I had accidentally cut into the wooden sawhorse that was holding up the steel sheet, but I've done that before with no problem. After a short while the problem fixed itself and the rate of cutting went back to a fast normal. Anyone know why this happened?: Sounds like the abrasive surface got blinded, coated with something that prevented the abrasive particles from touching the steel. It is possible to have vastly different hardnesses in a single piece of steel. Case hardening, carburizing, induction hardening, heat affected zone from welding, differences in work hardening, and presence of inclusions are some of the things that can create hardness variation within a single piece. But... sounds like you are working with a sheet which is unlikely to have any of these conditions. So... it was probably the grinding disk

Q:How are steel coils used in the production of automotive chassis?: Steel coils are used in the production of automotive chassis as they provide the primary material for constructing the framework of the vehicle. These coils are first processed and shaped into the desired form, such as beams or plates, which are then welded together to form the chassis. The high strength and durability of steel make it an ideal choice for withstanding the stresses and loads experienced by the chassis, ensuring the safety and structural integrity of the vehicle.

Q:How are steel coils processed for specific applications?: Steel coils are processed for specific applications through a series of carefully planned steps. The process begins with the selection of the appropriate grade and thickness of steel, which is determined based on the requirements of the end application. Once the steel coils are received, they undergo a series of processing steps to transform them into the desired product. The first step in processing steel coils is known as uncoiling, where the coil is unwound and straightened. This ensures that the coil is flat and ready for further processing. The uncoiled steel is then cleaned to remove any dirt, oil, or rust that may be present on the surface. This is typically done through a process called pickling, which involves immersing the steel in a bath of acid to remove any impurities. After cleaning, the steel undergoes various shaping processes depending on the desired application. This can include processes such as slitting, where the coil is cut into narrower strips, or shearing, where it is cut into specific lengths. These shaping processes are often performed using specialized machinery that can handle the high strength and thickness of steel. Once the steel has been shaped, it may undergo additional processes to enhance its properties. For example, it may be heat treated to increase its strength or hardness, or it may undergo a coating process to improve its corrosion resistance. Coating processes can include techniques such as galvanizing, where the steel is coated with a layer of zinc, or painting, where it is coated with a layer of paint. Finally, the processed steel coils are inspected for quality and undergo any necessary finishing processes. This can include processes such as trimming the edges to remove any irregularities, or applying protective coatings to prevent damage during transportation or storage. Overall, the processing of steel coils for specific applications is a complex and carefully controlled process. It involves a combination of shaping, cleaning, coating, and finishing processes to ensure that the steel meets the required specifications and is ready for use in various industries such as automotive, construction, and manufacturing.
