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: Some stainless steel are magnetic and some aren't. The real high grade stainless steels aren't magnetic.Stainless is just regular steel with varying degrees of nickel and chromium alloys mixed in the batch. The more nickel and chromium the less likely to be magnetic. A lot of stainless exhaust pipes and barbecue grills claim to be stainless, and yet they still rust and tend to be magnetic. They must use the bare minimum of nickel and chromium in the melted batch just to claim the title of stainless steel. Nickel and chromium are quite expensive and they are what gives the steel the anti-corrosion and extreme hardness characteristics along with loss of magnetism of the steel. If you have stainless steel that is magnetic , it is a good sign it is stainless steel that barely meets the criteria of true stainless steel.

Q: How are steel coils used in the production of automotive wheels?: Steel coils are used in the production of automotive wheels as they are shaped and molded into rims before being welded or bolted onto the wheel hubs. The steel coils provide the necessary strength and durability required for the wheels to handle the weight and stresses of the vehicle, ensuring a safe and reliable driving experience.

Q: What are the common size limitations for steel coil production?: The common size limitations for steel coil production depend on various factors such as the type of steel, manufacturing equipment, and transportation constraints. However, generally speaking, steel coils are typically produced within a range of widths between 600mm to 2,000mm, with thicknesses ranging from 0.2mm to 25mm. The maximum weight of a steel coil is usually around 25 metric tons, although this can vary depending on the specific production facility and transportation capabilities.

Q: I am going to be working as a mechanic at my school and I just wanted to know if I should get the steel toe boots or regular. I heard that steel toe boots can be dangerous and uncomfortable. The mechanics recommended getting steel toe to be safe but i'm not sure.: If I was you, I would get steel toe boots, because I got soft toe boots and at the toe part, it dented in, because I used them for riding dirtbikes, I wish I would of got steel toe boots, u should get steel toe because later on you might wish u would of got them:) hope this help

Q: Can steel coils be coated with UV-resistant materials?: Yes, steel coils can be coated with UV-resistant materials. This coating helps protect the steel from the harmful effects of ultraviolet (UV) radiation, such as fading, discoloration, and degradation. UV-resistant coatings are commonly used in various industries to enhance the durability and longevity of steel coils, particularly when exposed to outdoor or high UV environments.

Q: What are the different types of steel coil edge condition options?: There is a variety of steel coil edge condition options available, each offering distinct characteristics and advantages. The most common types are as follows: 1. Mill Edge: This is the basic and widely used type of steel coil edge condition. It occurs naturally during the hot rolling process and is characterized by a rough and uneven edge. Mill edge coils are typically suitable for applications where edge quality is not crucial, such as general fabrication. 2. Slit Edge: Slit edge coils are produced by cutting the edges of the steel coil using a slitting machine. This process results in 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 the automotive or electrical industries. 3. Trim Edge: Trim edge coils are similar to slit edge coils but undergo an additional trimming process to eliminate any defects or imperfections from the edges. This creates 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 injuries during the 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 utilized in applications where the coils will come into contact with delicate materials or surfaces, as it helps prevent scratching or damage. It is important to consider the specific requirements of the application and the desired outcome when choosing a steel coil edge condition. Each type offers its own unique benefits, and factors such as precision, appearance, safety, and functionality should be taken into account when selecting the appropriate option.

Q: What does "steel roll number" mean?: The coil numbers in the steel industry are generally applicable to rolled round steel bars. A coil of steel has a specified length and weight. Different rolls have different volumes

Q: What are the different surface treatments for steel coils?: Steel coils can undergo various surface treatments to achieve different outcomes and applications. Some commonly used treatments include: 1. Hot-dip galvanizing: Steel coils are immersed in molten zinc, which forms a protective layer on the surface. This treatment provides excellent corrosion resistance for outdoor use. 2. Electro-galvanizing: A thin layer of zinc is electroplated onto the steel coils. It offers good corrosion resistance and is suitable for indoor applications. 3. Powder coating: Dry powder is applied to the surface and heated to form a durable coating. It provides excellent corrosion resistance and comes in different colors and finishes. 4. Paint coating: Steel coils can be coated with liquid paint, offering both corrosion resistance and aesthetic appeal. The thickness and finish can be customized according to the desired look and level of protection. 5. Phosphating: Steel coils are immersed in a phosphate solution, creating a thin layer that enhances paint adhesion and improves corrosion resistance. 6. Chromate conversion coating: Steel coils are immersed in a solution containing chromium salts, providing excellent corrosion resistance and acting as a primer for subsequent paint or powder coating. 7. Zinc-nickel plating: A layer of zinc-nickel alloy is electroplated onto the steel coils, offering superior corrosion resistance compared to pure zinc plating and is suitable for demanding environments. These are just a few examples of the many available surface treatments for steel coils. The choice depends on factors such as application, desired corrosion resistance, aesthetic requirements, and budget. It is important to carefully consider project needs and consult with experts to determine the most suitable treatment.

Q: I want to know where cold formed steel framing is used, is every steel frame we see in a construction sites like houses, building and bridges cold formed steel frames? or hot formed steel framing?I also read that cold formed steel framing is used for floors, is the steel frame beneath the floor's concrete cover?Thank u very much!!: It will vary from location to location. A possible way of telling is how the material is joined. If the material is riveted together it is likely cold rolled. If the material is welded then its probably normalized steel (possibly annealed but less likely). Cold rolling increases the yield strength of the material so less of it is needed. However, it also make the material more brittle. Welding creates defects in the region surrounding the weld and these are more likely to grow and cause failure in a cold rolled steel than a normalised or annealed steels. In addition the heat from the welding will change the microstructure that was deliberately introduced by the cold rolling process resulting in a localised drop in yield strength. Normalised and annealed steels are more ductile and tougher than Cold rolled steel but they have a lower yield strength. Because they are tough and ductile they are less sensitive to crakcs and defects so welding won't lead to as big a reduction in strength. Another possible consideration is the environment they are used in. Steels exhibit a transition temperature (actually more like a range) where they go from behaving like a ductile material to a brittle material. A well known example of what this can cause are the Liberty ships in WW2 (Supply vessels from the US to the UK). These were made by welding together sheets of cold rolled steel to form one continuous Hull. Unfortuantely the transiton temperature of the steel taht was sued was around 4 degrees while the Baltic Ocean is about 0 degrees. As a result small cracks would grow and then when the reached a critical size they would tear through the ship at the speed of sound in the metal (1500m/s) and these massive cargo ships would literally snap like twigs. So, if the steel is being used somewhere really cold its unlikely to be Cold rolled too.

Q: I know that steel wool is coated with... something... that protects it from rusting. I need to know what that is, and how to get it off.: It will be very effective if you remove the oil by appling protective polymer spin coating to the edge, top and underside of the wafer, which makes those surfaces impervious to most chemical etchants. To learn more about the spin coating theory you may check out the following source.
