- Q: What is the difference between regular steel stainless steel? Why does steel rust but stainless wont? Is stainless some kind of alloy or something? Any knowledgeable input would be great. Thanx!
- In metallurgy, stainless steel is defined as a steel alloy with a minimum of 11.5% chromium content by mass. Stainless steel does not stain, corrode or rust as easily as ordinary steel (it stains less), but it is not stain-proof. It is also called corrosion resistant steel when the alloy type and grade are not detailed, particularly in the aviation industry. There are different grades and surface finishes of stainless steel to suit the environment to which the material will be subjected in its lifetime. Common uses of stainless steel are cutlery and watch straps. Stainless steel differs from carbon steel by amount of chromium present. Carbon steel rusts when exposed to air and moisture. This iron oxide film is active and accelerates corrosion by forming more iron oxide. Stainless steels have sufficient amount of chromium present so that a passive film of chromium oxide forms which prevents further corrosion
- Q: Is steel harder than iron or is iron harder than steel?Please explain... and help!Thanks
- steel is harder than iron Iron is a chemical element. It is a strong, hard, heavy gray metal. It is found in meteorites. Iron is also found combined in many mineral compounds in the earth's crust. Iron rusts easily and can be magnetized and is strongly attracted to magnets. It is used to make many things such as gates and railings. Iron is also used to make steel, an even harder and tougher metal compound. Steel is formed by treating molten (melted) iron with intense heat and mixing it (alloying) with carbon. Steel is used to make machines, cars, tools, knives, and many other things.
- Q: I am looking for a steel taper kit to help me start stretching my earlobes. I wanted something like the following but in steel instead of acrylic. Preferably something under $40 and from a reputable website. I don't know how much damage acrylic tapers can do in the few seconds it would be inside my earlobe, but I would rather use steel just to be safe. I will be forever grateful if anyone can help.

- Q: I looking at replacing a few of the panels on my car with either Carbon Fiber or High Tensile Steel to shave off some weight and increase mpg and take some time off my quarter mile. Which is better: Carbon Fiber or High Tensile Steel?
- Because no matter how hard the helmet is it can not prevent brain damage from your brain slapping the inside of your skull. If the helmet was able to absorb the energy from an impact and prevent you brain from moving inside your skull it would have to be huge and everyone would look like bubble heads riding on bikes. The sides would have to be around 12 inches thick on each side and top to provide that much protection and would probably break your neck if you were in a wreck. Hope I have been helpful.
- Q: What are the common challenges in steel coil manufacturing?
- Some common challenges in steel coil manufacturing include maintaining consistent quality, managing the weight and size of coils, ensuring proper surface finish, minimizing defects such as dents or scratches, preventing coil damage during handling or transportation, and optimizing production efficiency to meet customer demands.
- Q: What is the weight of a typical steel coil?
- The weight of a typical steel coil can vary depending on its size and thickness. However, a common range for the weight of a steel coil is between 5 to 15 tons.
- Q: So...I'm learning about how steel is made and I'm wondering if there is a more environmentally friendy method. I view it as unfriendly b/c of the oxygen that is injected when the steel is in the blast furnace or electric arc furnace. This oxygen bonds w/ the carbon to produce CO and CO2. THis is necessary to reduce the amount of carbon content to produce harder steels. So what other methods are there that can be used w/o having to end up w/ co and co2? thanks
- From what I understand of it, US steel is better as the steel is more recycled than Canadian, so a lot of that oxygen / CO2 has already taken place compared to working from ore. The second reason US steel is environmentally ahead of Canadian is that US tends to use Electric Arc, while Canadian uses Basic Oxygen, Basic Oxygen uses more energy than electric arc, and I think it also uses more oxygen, but I would suspect that oxygen that it uses is 'waste oxygen' and not converted into Co2 because the Co2 process is limited by the carbon, and steel only has so much carbon.
- Q: How are steel coils used in the manufacturing of railway wagons?
- Steel coils are used in the manufacturing of railway wagons as they serve as a raw material for various components such as the wagon body, chassis, and structural parts. These coils are processed, cut, and shaped to form the required parts, ensuring the wagon's strength, durability, and load-bearing capacity. The steel coils are transformed into sheets, plates, or beams, which are then welded, bolted, or riveted together to construct the wagon's framework and body. Overall, steel coils play a vital role in providing the necessary strength and structural integrity to railway wagons.
- Q: ...particularly for jewelry?
- Surgical steel can be stainless these days, but it used to refer to a particular hardness of steel that was so tempered that it could be made to hold a very sharp edge for a prolonged period of time.
- Q: What are the different methods of edge trimming for steel coils?
- There are several different methods of edge trimming for steel coils, including slitting, shearing, and laser cutting. Slitting involves cutting the coil into narrower strips using circular blades. Shearing involves cutting the edges of the coil using a straight blade. Laser cutting uses a high-powered laser to precisely trim the edges of the coil.
