Q: Can you recycle steel? And if you wanted to buy some recycled steel, where would you get it?: Steel is the most recycled material. But in recycling steel you would need the usual equipment in a foundry. The finished (recycled) product cannot be discerned visually. You cannot differ it from those coming from virgin steel ingots. The finished product (or steel material) would have to depend on your requirement, whether it is for structural, architectural or otherwise. For your requirement (enough to build a cruise ship), it would be best to go to a smelter. You might get better prices and quality compared to that from a scrap yard.

Q: What are the challenges in coil blanking for high-strength steel?: Coil blanking for high-strength steel presents several hurdles due to the unique properties of this material. One of the main obstacles lies in the steel's high tensile strength, which makes cutting and blanking more difficult when compared to traditional steel grades. High-strength steel is typically harder and less malleable, resulting in heightened tool wear and greater cutting forces. Therefore, specialized cutting tools capable of enduring these extreme conditions are necessary. Additionally, the augmented cutting forces can cause increased vibrations, potentially impacting the accuracy and quality of the blanks. Another challenge arises from the spring-back effect displayed by high-strength steel after it is cut. This means that the material tends to return to its original shape, creating difficulties in achieving precise dimensions and tolerances in the blanks. Consequently, careful consideration and adjustment of the cutting parameters are required to minimize the spring-back effect. Furthermore, high-strength steel often contains a higher carbon content, leading to increased work hardening during the blanking process. As a result, the material becomes even harder and more brittle, making it more susceptible to cracks and fractures. To overcome this challenge, proper lubrication and cooling techniques are crucial in reducing heat buildup and minimizing the risk of cracking. Additionally, the heightened strength of the steel can also impact overall production efficiency. The increased cutting forces and tool wear may necessitate a reduction in cutting speeds, resulting in longer processing times. This can affect the productivity and throughput of the coil blanking process, requiring meticulous optimization and planning. In conclusion, the challenges involved in coil blanking for high-strength steel encompass increased cutting forces, tool wear, the spring-back effect, work hardening, and reduced production efficiency. Overcoming these challenges necessitates the use of specialized cutting tools, precise cutting parameters, proper lubrication and cooling techniques, and meticulous optimization of the production process.

Q: I have been thinking of buying a knife that says it has damascus steel. The reason for the question is that many people told me that damascus steel does not exist anymore, and that damascus nowadays is fake. Is this true???: damascus steel it says is made from ore containing either tungsten or vanadium, although most tools I've seen are made from chrome vanadium, it wouldn't be hard in this day and age to get the proper material. Although it DOES say in wikipedia that apparently the technique died out a long time ago due to shortage of the ore. Then it talks about reproduction attempts. So theoretically, yes, it could be the deal deal. But it does refer at the bottom about damascend steel which is made with a different technique, you could be buying one of those. NEXT TIME JUST LOOK UP THE ARTICLE YOURSELF AND READ IT

Q: What are the different types of steel coil slitting processes?: There are several types of steel coil slitting processes, including rotary slitting, loop slitting, and pull-through slitting.

Q: This needs to be in a percentage by mass. Could you please also reference where this info has come from. Thanks.: pl. be specific about the type of steel: (Steel is a metal alloy whose major component is iron, with carbon content between 0.02% and 1.7% by weight. Carbon is the most cost effective alloying material for iron, but many other alloying elements are also used.[1] Carbon and other elements act as a hardening agent, preventing dislocations in the iron atom crystal lattice from sliding past one another. Varying the amount of alloying elements and their distribution in the steel controls qualities such as the hardness, elasticity, ductility, and tensile strength of the resulting steel. Steel with increased carbon content can be made harder and stronger than iron, but is also more brittle. The maximum solubility of carbon in iron is 1.7% by weight, occurring at 1130° Celsius; higher concentrations of carbon or lower temperatures will produce cementite which will reduce the material's strength. Alloys with higher carbon content than this are known as cast iron because of their lower melting point.[1] Steel is also to be distinguished from wrought iron with little or no carbon, usually less than 0.035%. It is common today to talk about 'the iron and steel industry' as if it were a single thing; it is today, but historically they were separate products. Currently there are several classes of steels in which carbon is replaced with other alloying materials, and carbon, if present, is undesired. A more recent definition is that steels are iron-based alloys that can be plastically formed (pounded, rolled, etc.). Iron alloy phases : Austenite (γ-iron; hard) Bainite Martensite Cementite (iron carbide; Fe3C) Ferrite (α-iron; soft) Pearlite (88% ferrite, 12% cementite) Types of Steel : Plain-carbon steel (up to 2.1% carbon) Stainless steel (alloy with chromium) HSLA steel (high strength low alloy) Tool steel (very hard; heat-treated) Other Iron-based materials : Cast iron (2.1% carbon) Wrought iron (almost no carbon) Ductile iron)

Q: Which of the two are better for exhaust manifolds, im guessing the stainless steel right?: Cast iron. That's what OEMs use obviously it's better. Bring on the Thumbs Down from the peanut gallery.

Q: I need to know the density of steel as one of my physical properties of steel. Any answers? If u have more physical or chemical properties of steel, that would help to thanks.: It depends on what kind of steel it is. Martensitic steel has a lower density than austenitic steel. However, a good number for a typical steel is 0.286 pounds per cubic inch (7.92 grams per cubic centimeter).

Q: Corten steel tends to overheat in hot environments? (for example copper heats up under the sun): Weathering steel, best-known under the trademark COR-TEN steel and sometimes written without the hyphen as Corten steel, is a group of steel alloys which were developed to obviate the need for painting, and form a stable rust-like appearance if exposed to the weather for several years. Overheating ? It's not possible for a metal to get hotter than it's environment unless there is a source of radiation. The sun shining on a metal will heat up a bit, as will any material, but the amount is small and depends on the surface reflectivity. Define what you mean by overheating. .

Q: Can steel coils be coated with magnetic materials?: Yes, steel coils can be coated with magnetic materials.

Q: I want to make a stock removal knife, but I am really confused about what steel to use. I am just a beginner but I read o1 steel is great? Also I am kind of on a budget.: O-1 is an excellent steel. If you've never made a knife before find an old file and use it. My first knives weren't that good, it took a little practice to get the geometry right so be prepared to burn some steel. The advantage of a file is it is already hardened, unless you have a torch or forge that will be near imposable for you to do. The most important thing in knife making is the heat treating. The best steel wont perform like it's supposed to. If you decide to use a file grind your blade out, keep the steel cool; do not let it get any color in it (brown, blue, purple) as this destroys the temper. When your finished put the blade in the oven at 400 deg for an hour. It should have a good hardness for a knife then. As for me, I use old car springs(5160), saw blades(L-6) for many of my blades, Good luck.
