5.FAQ of Cold Rolled Steel

We have organized several common questions for our clients，may help you sincerely：

1.How to guarantee the quality of the products？

We have established the international advanced quality management system，every link from raw material to final product we have strict quality test；We resolutely put an end to unqualified products flowing into the market. At the same time, we will provide necessary follow-up service assurance.

Q: why do you need to heat steel when hardening, molecules etc etc: Heat treatment deforms the crystal micro structure of the Steel. With heat (and cold) treatment the organisation or Diffusion of the micro particles can be manipulated. There is a higher concentration of particles after heat treatment, thus making the micro structure of the steel more dense, and the physical performance of the steel better. Stronger. Hope this helps ! Please like.

Q: I heard on some shows that you can carbonise steel by heating it red hot then dropping it in black oil. i cant find this no where online, and the process for commercial carbon steel is totally different. can you really carbonise regular steel by heating it to red hot then dropping it in regular black oil. i saw it on mythbusters once. when the made carbon steel hammers to test if 2 hammers smashed together will shatter: Carburized steel is not the same thing as carbon steel. All steel has carbon in it, but carbon steel is defined as Steel is considered to be carbon steel when no minimum content is specified or required for chromium, cobalt, molybdenum, nickel, niobium, titanium, tungsten, vanadium or zirconium, or any other element to be added to obtain a desired alloying effect; when the specified minimum for copper does not exceed 1.04 percent; or when the maximum content specified for any of the following elements does not exceed the percentages noted: manganese 1.65, silicon 0.60, copper 0.60. Carburizing is a surface treatment. Dropping hot steel in oil is oil quenching. It might get a little carbon in the surface, but oil quenching is mainly used as a slightly slower quenching process than water quenching, not for carburizing. Once it starts cooling down the carbon won't diffuse in. Quenching is used to change the hardness. The simplest way to carburize steel is to pack charcoal around it and heat it to 900 C or so. Industrial processes use a gas like carbon monoxide, but that's mostly just for easier process control.

Q: How are steel coils packaged for transportation?: Steel coils are typically packaged for transportation using a variety of methods to ensure their safe and secure delivery. The packaging process involves several steps to protect the coils from damage during transit and to facilitate their handling and loading onto trucks, ships, or trains. Firstly, steel coils are tightly wound and bound using steel straps or bands to keep them compact and prevent unwinding. These straps are usually made of high-strength steel and are securely fastened around the circumference of the coil at regular intervals. This helps to maintain the coil's shape and prevent any movement during transportation. Next, the coils are often placed on wooden or steel pallets to provide a stable base and facilitate handling with forklifts or cranes. The pallets are usually sized to fit the dimensions of the coils and are designed to withstand the weight and stress of the loaded coils. To provide additional protection, steel coils are often covered with a layer of protective material such as plastic or paper to shield them from moisture, dust, and other potential contaminants. This wrapping also helps to prevent scratching or damage to the outer surface of the coils. Furthermore, to secure the coils and prevent shifting during transit, they are often placed within a steel or wooden crate. These crates provide an extra layer of protection and stability, particularly for larger coils or when multiple coils are being transported together. Finally, once the coils are properly packaged, they are typically loaded onto flatbed trucks, shipping containers, or railway cars for transportation. During loading, proper care is taken to ensure that the coils are positioned securely and that weight distribution is balanced to prevent any potential damage or accidents during transit. In summary, steel coils are packaged for transportation by tightly binding them with steel straps, placing them on pallets, covering them with protective material, and, if necessary, enclosing them within crates. This packaging process helps to safeguard the coils and ensure their safe and efficient transportation to their destination.

Q: What are the advantages of using galvanized steel coils?: There are several advantages to using galvanized steel coils. Firstly, galvanized steel is highly resistant to corrosion, which means it can withstand exposure to moisture and other harsh environmental conditions without rusting. This makes it a durable and long-lasting material for various applications. Secondly, galvanized steel coils have a protective zinc coating that acts as a barrier against damage and provides excellent structural strength. Additionally, galvanized steel coils are versatile and can be easily formed, welded, and painted, making them suitable for a wide range of industries and projects.

Q: What's the best material for color coated steel coil?: Galvanized steel sheet with hot-dip galvanized or zinc plated surface.

Q: Is steel easier to weld?Which is more brittle/less flexible?: You should not attempt to do any traditional welding of steel to aluminum as they can form a hard and brittle inter metallic compound known as iron aluminide. You would have to employ a process that did not melt either species. Cladding could be an option but you are kind of limited to flat products that are sandwiched together. There is also explosive which does almost the same thing as cladding. Friction stir welding might be possible but I cant vouch for that. The temperature does get pretty hot, so I am not sure what would happen. But any of these suggestions would take specialized equipment not available to the average user. For weight, Al is 2.7 g/cc and Iron is about 7.8 so it is about 3 times heavier for the same volume. How strong either of them are greatly depends on specific alloys and heat treatment. I think some of the strongest aluminum alloys have a yield strength of about 50,000 psi which would relate to a relatively weak steel. For steel, there are alloys that can have yield strengths in the hundreds of thousands psi.

Q: Which one has more electrical resistivity? Wood or steel? And why?I know that the resistivity depends on the material of the conductor, but i want a perfect explaination please.Thnx in advance :): Steel is a conductor while wood is an insulator. There are no free electrons available in wood for conduction of electricity to take place. So wood has more electrical resistivity than that of steel.

Q: What is the average lifespan of a steel coil?: The average lifespan of a steel coil can vary depending on various factors such as its quality, usage, maintenance, and environmental conditions. However, on average, a well-maintained steel coil can last anywhere from 10 to 30 years.

Q: What are the different certifications required for steel coil manufacturers?: Some of the different certifications required for steel coil manufacturers include ISO 9001, ISO 14001, OHSAS 18001, and various industry-specific certifications such as the American Society for Testing and Materials (ASTM) certifications. These certifications ensure that the steel coil manufacturers meet quality, environmental, and occupational health and safety standards.

Q: Steel being my favorite type, I just picked up Heart Gold today, my gf got Soul Silver...I was wondering which steel types are available and somewhat easily obtainable in HG (and/or what is the earliest steel type I can get?): There aren't many Steel types in the Johto and Kanto regions. You'll have to rely on trading from Sinnoh and Hoenn to get most of the Steel types. In Soul Silver you can get a Skarmory on Rt 43, I believe. Ask your gf to catch you one when she gets there.
