Q: What are the different surface finishes for steel coils?: The different surface finishes for steel coils include hot rolled, cold rolled, galvanized, coated, and brushed.

Q: I have one and wonder how much force this can take since it does seem like you can bend it(Sure it's impossible with hands), but I don't want to try that cause i don't want to break it. Many people say that it's really hard and can handle a hammer smash? is that true and can it even make it through more force. Cause steel is harder than iron and iron is pretty hard... So how much can i trust this locks security, i mean if i put at at a door would some thiefes be able to break it, if they had the right tools??: It's hard to give you a quantitative answer. There are different grades of testing standards for padlocks. It comes under the ASTM F883. You need to be more specific. The link only gives a picture and no details about the lock. But in general, stainless steel locks are pretty darn strong. Also, you are under the wrong impression about steel vs iron. Iron is a component of steel. Pure iron is very ductile and is softer than steel. Cast iron, is very hard, but is also very brittle and has limited uses. In general, mild steel is realitively soft and ductile. But, there are many different alloys of steel and some have hardnesses and strengths higher than cast iron. Stainless steel is typically more ductile that mild steel because of the smaller amount of iron in the recipe. There are exceptions to that as well. The 400 series of stainless steels have higher amounts of iron and can be heat treated to hardnesses equaling the better steel alloys.

Q: i have a guitar with three nylon three steel strings. Am i able to replace the nylons with steel strings?: DO NOT PUT ACOUSTIC (steel) STRINGS ON A CLASSICAL GUITAR. Classical guitars are not built to withstand the tension of steel strings. putting steel strings on a classical guitar can cause irreparable damage to the neck, where the neck joins the body and the heel. Classical guitars have nylon strings. Yes 3 of them look like steel strings, but these are actually metal wrapped around a nylon core. Acoustic guitars are metal strings. The wound strings on an acoustic have a metal string core. Classical guitars tend to have a wider neck and are more for classical music, flamenco, finger picking, etc. Acoustic guitars can have lower tension strings put on them (e.g. martin silk and steel) as the guitar can be adjusted to take the lighter string tension placed on the neck and heel. Martin Silk and Steel Strings can also be put on a classical guitar as they have a lot lower tension than steel and they give a louder more acoustic sound.

Q: I am working on a hydrogen generator, but the stainless steel I am using corrodes and turns the water brown. Can anyone tell me if there is stainless steel that does not corrode, and if so, what is it called and where can I get some.Thank you.: Look okorder /

Q: If steel can rust with saltwater... then why are ships made of steel? can't we just use other metals like aluminium etc?: also add to answers above (now below), zincs are mounted on the hull and shaft to draw the electrolysis to them instead of the hull and are easily replaced by a competent diver

Q: What processes and materials are used in the production of chrome steel: Go to the process section and find point 6 (explains when alloys are added). Chrome is added at this point, usually in the form of ferrochrome alloy (FeCr). Many kinds of chrome steel also contain nickel. The strengthening effect on steel by forming stable carbide grains at the grain boundaries and the strong increase in corrosion resistance made chromium an important alloying material for steel. The high speed tool steels contain between 3 and 5% chromium.

Q: How are steel coils protected from extreme weather conditions?: Steel coils are typically protected from extreme weather conditions through the application of a weather-resistant coating or paint. This coating acts as a barrier, shielding the steel from moisture, UV radiation, and other environmental elements that could cause corrosion or damage. Additionally, steel coils may be stored in covered or enclosed areas to further protect them from rain, snow, and other severe weather conditions.

Q: How are steel coils tested for compliance with industry standards?: Steel coils are tested for compliance with industry standards through a series of rigorous quality control measures. These tests are conducted to ensure that the coils meet the necessary specifications and are suitable for use in various applications. One of the primary tests performed on steel coils is the dimensional inspection. This involves measuring the thickness, width, and length of the coils to ensure they meet the specified tolerances. Any deviations from the required dimensions can indicate a manufacturing defect or potential issues during fabrication. Another critical test is the visual inspection, where trained inspectors carefully examine the coils for any surface defects such as scratches, dents, or cracks. These defects can affect the performance and durability of the steel coils, making it essential to identify and rectify them before they are supplied to customers. Furthermore, mechanical properties testing is conducted to assess the strength, elasticity, and toughness of the steel coils. This includes tests like tensile strength, yield strength, and elongation measurements. These tests help determine the suitability of the coils for specific applications and ensure they meet the required performance standards. Additionally, chemical composition analysis is performed to verify the elemental composition of the steel coils. This analysis is crucial as it ensures that the steel meets the required chemical requirements, including the presence of specific alloying elements. Deviations in composition can impact the overall quality and performance of the coils. Corrosion resistance testing is also important, especially for coils used in environments with high humidity or exposure to corrosive substances. Coils are subjected to salt spray or humidity chambers to simulate real-world conditions and evaluate their resistance to corrosion. Lastly, various non-destructive testing techniques, such as ultrasonic testing and magnetic particle inspection, are used to detect internal defects or discontinuities in the steel coils. These tests help identify any hidden flaws that may compromise the structural integrity of the coils. Overall, steel coils undergo a comprehensive range of tests to ensure compliance with industry standards. By conducting these tests, manufacturers can guarantee that the coils meet the required specifications, providing customers with high-quality products that meet their specific needs.

Q: case hardening steel is adviced or thru hardening steel is most suitable?: I don't know your application, but here is some advice. Case hard provides a hard shell around soft steel, depending on the bake, the case is usually .002-.008 thick. (thousands of an inch) Heat treated steel or tool steel is hard all the way thru. Case hardening, provides toughness with flexibility, however, once it's compromised, the part is scrap. Hardend tool steel is extreemly hard throughout and the harder it is, the more brittle it becomes. The application of the part will help you to determine the material needed. For instance; Plastic injection molds are very hard so the hot plastic wont erode them over years of use. Punch Press dies aren't as hard but are tougher to withstand the shock. Machine bolts are case hardened so they can last, but soft enough to allow some stretching during tightening. Either way, the time in mfg will be about the same. Most tool steels today cut like cheese, but take time to be heat treated. Tool steel will cost a bit more than low carbon steel. Low carbon steel is as machinable, and cheaper, but, again, the baking period is as long or longer than tool steel. There are a lot of materials on the market today that maintain the durability of heatreated steel without having to go thru that process. 4140, ( or chrome/moly) comes to mind. There are also some 400 series stainless that work as well, and others. You need to determine strength, flexibility, ease of mfg, cost and repairability when considering which steel to use.
