Q: What are the common sizes of steel coils used in the industry?: The common sizes of steel coils used in the industry vary depending on the specific application and requirements. However, some commonly used sizes include widths ranging from 24 to 72 inches and thicknesses ranging from 0.010 to 0.250 inches.

Q: I thought it was STAINLESS STEEL! I have stainless steel can openers spatulas that are rusty. What's up with that? did you know that braces on people's teeth are made of stainless steel? That's why they call people metal-mouth. I used to have braces.: You can rub the rust off with anything, from steel wool to Ajax. Although if you've previously used steel wool to clean it, that could be why it rusts. We had that problem manufacturing stainless steel railing and had to put it together on an aluminum table and polish welds with grinding wheels that never touched steel. What rusts are steel particles picked up on the stainless surface. Another possibility is that some stainless is more magnetic and usually also heat-treatable. It has just enough chrome in it to classify as stainless but can get minor surface rust. Not nearly as much as plain steel, though. Use a scouring powder like Zud or Barkeepers Friend and a cloth or sponge to polish if it's a sheetmetal surface rather than a bar grille, because these have oxalic acid and no bleach. They don't leave corrosive traces of chlorine behind. In fact, oxalic acid reduces rust to iron powder. Which is really neat if you need to clean a small rusty item--stir one of these powders into water, drop in the rusty piece and check it from time to time. Rinse off any abrasive powder, dry it well and oil it. When the rust is gone, it leaves a fine matte finish behind.

Q: what pokemon are week to steel type pokemon like lucario? help please, and thank you.: Rock pokemon are weak against steel type moves.

Q: If you combine stainless steel with gold, does that make stainless gold?: Stainless steel, I believe, was an actual trade name of a british cutlery company's knives, once the ability to create iron-chromium alloys was mastered. Stainless steel's main alloying agent that prevents it from rusting, is Chromium. The Chromium in the steel creates an protective layer (not unlike rust), which acts as a protectant for the rust-prone iron...keeping real rust away. I am no metallurgist, but I have not heard of gold being used as an alloying agent in common steels. I'm not even sure they would mix. Not all metals can be stirred together successfully. Even if gold could be used as an alloying agent for steel, it would need to be in such a small percentage, you would not end up with a metal that was gold in appearance...so it would still look like steel of some sort. The funny part is, gold is already stainless, and does not tarnish or rust as it is.

Q: .Yea, so I just saw the old Conan movie with Arnold. Good movie, but I still don't get it. What IS the riddle of steel???I get that like from the begining Conan's dad is like telling him a story about Crom and giants, and people got steel once Crom killef the giants. Then, later on in the movie Conan's talking to his lil' asian homie, and Conan tells him that when he dies... he'll go before Crom, and Crom will ask him what the riddle of steel is, and if he doesn't know it he'll get kicked out of barbarian heaven!But, what is the riddle of steel???C'mon guys... I want to in to barbarian heaven! LolBut, seriously though... what us it???.: This Site Might Help You. RE: Movies- Conan: What is the riddle of steel? . Yea, so I just saw the old Conan movie with Arnold. Good movie, but I still don't get it. What IS the riddle of steel??

Q: I understand that Stainless Steel is a low carbon steel having minimum 10.5% chromium content in it there r 60 different type of stainless steel. Kindly informa) Is this info correct?????b) Which stainless steel can get rusted or can have superficial rust????: Stainless steel is a generic term for a whole range (there are more than 60 types) of Fe-Cr alloys. They all contain some amount of C and some alloys include a good number of other alloying elements. In almost all cases, the materials have corrosion resistance due the Cr atoms that are in solid solution with the Fe matrix. Under corrosive conditions, the Cr forms a thin tight coherent layer of Cr-oxide. This Cr oxide coating prevents further corrosion so long as it is not chemically or physically removed. If the SS has been subject to mechanical abrasion, the corrosion resistance can sometimes be restored by a light exposure to nitric acid which passivates the surface, restoring the Cr-oxide layer. The carbon content is an important factor in corrosion preformance but so is the heat treatment. Under the wrong conditions and in different environments, all SSs can rust. One of the most common corrosion problems is sensitization which occurs in the heat affect zone (HAZ) around welds. If the C content is high enough and the heat is high enough, the Cr atoms in solid solution form Cr-carbides and are no longer available to form a protective Cr-oxide. The corrosion resistance can be restored by appropriate heat treatment.

Q: How are steel coils inspected for paint adhesion?: Steel coils are inspected for paint adhesion using various methods and techniques. One common method is the tape test, where a strip of adhesive tape is pressed onto the painted surface and then quickly pulled off. The tape's adhesion to the paint is then assessed by examining the amount of paint that is removed from the surface. If the paint adheres well to the steel, only a small amount of paint will be lifted off by the tape. Another method used is the crosshatch adhesion test. In this test, a series of parallel cuts are made on the painted surface using a sharp blade, creating a crosshatch pattern. A piece of adhesive tape is then applied over the cuts and quickly pulled off. The amount of paint that is removed from the crosshatched area is evaluated to determine the paint adhesion. Additionally, a visual inspection is often conducted to assess the overall appearance and adhesion of the paint. Inspectors look for any signs of cracking, peeling, or bubbling of the paint, which could indicate poor adhesion. They also check for any areas where the paint may have chipped or flaked off. Furthermore, various laboratory tests can be performed to evaluate the paint adhesion on steel coils. These tests may include techniques such as the pull-off test, where a specialized device is used to measure the force required to pull off a small section of the paint from the surface. Other tests may involve subjecting the painted surface to extreme temperature or humidity conditions to assess how well the paint holds up under different environmental factors. Overall, a combination of visual inspections, tape tests, crosshatch adhesion tests, and laboratory tests are used to thoroughly inspect steel coils for paint adhesion. These tests help ensure that the paint adheres properly to the steel surface, providing a durable and long-lasting finish.

Q: Ok.. I was wondering if it's possible for me to recycle baked bean cans (steel)? And if so in Western Australia (that's where I live)?I love baked beans... and I also like skateboarding, so I thought if I kept my baked bean cans, that I could get them recycled somewhere and turn it into something I could skate on (rail, etc.). I'm just curious to know if all this is possible...Cheers. :): Steel is one of the most recycled materials on the planet... Unless you know a recycler/steel refiner/manufacturer however, it would be mighty difficult for you to have someone melt down all your baked bean (a somewhat American dish, I'd say) cans. Plus, think how many baked beans you'd have to eat to be able to build anything of substance. Don't know where you would take it in Australia - I'm in the US where a lot of municipalities collect mixed recyclables.

Q: What are the safety precautions when handling steel coils?: When handling steel coils, it is important to follow several safety precautions. First and foremost, workers should wear appropriate personal protective equipment (PPE) such as safety gloves, safety glasses, and steel-toed boots to protect themselves from potential injuries. Secondly, it is crucial to ensure that the area is clear of any obstructions or tripping hazards to prevent accidents. Additionally, workers should receive proper training on safe lifting techniques and use of lifting equipment to avoid strain or back injuries. It is also recommended to inspect the coils for any sharp edges or protruding objects before handling them. Lastly, communication and teamwork are essential to ensure the safe handling and maneuvering of steel coils, especially when using heavy machinery or cranes.

Q: Hi can someone help me pleaseis there any available data for mechanical behaviour of recycled steel, i need to compare them with new steel.: It is not clear from the question whether the recycled steel is used in its existing state or used as raw material for further fabrication. For the existing steel, you need to track down the original documents such as the ladle analysis and mill certificates certifying the material standards for which the steel was fabricated. Another alternative is take samples and conduct chemical and mechanical tests on the steel. Also the date of when the structure was built from which the steel is recycled may help indicate whether it is (American Society for Testing and Materials) Standard ASTM A7 or ASTM A36 or another type of steel. In most cases, the steel is used as raw material to make new steel. The mill will adjust the additives to produce steel with the required chemical and physical properties to meet the ASTM standards specified.
