Q: How are steel coils inspected for mechanical properties?: Steel coils are inspected for mechanical properties through a series of tests and measurements. These include hardness testing, tensile testing, and elongation testing to determine the steel's strength, ductility, and overall quality. Additionally, non-destructive testing methods like ultrasonic testing and magnetic particle inspection are used to detect any potential defects or flaws in the coils. Overall, a combination of these inspection techniques ensures that steel coils meet the required mechanical properties for their intended applications.

Q: i have purchased a high dollar Martin guitar and i was wondering if there are many people out there that have used steel string acoustics for classical and flamenco guitar playing.otherwise i will need a nylon stringeror.. uld i put nylon strings on an old yamaha steel string guitar that i have?: If the guitar was designed for nylon strings, then don't put steel strings on it!

Q: How are steel coils used in the manufacturing of lighting fixtures?: Steel coils are commonly used in the manufacturing of lighting fixtures as they provide a sturdy and durable framework for the fixtures. The coils are often shaped and welded to create the desired structure, ensuring that the lighting fixtures are robust and can withstand various installation environments. Additionally, steel coils can be coated or painted to enhance the aesthetics of the fixtures, making them more visually appealing.

Q: I went to the store to get metal to make a knife and they had weldable steel and plate steel. Which one would be best/ which steels would be best for what i want to do?: Weldable steel is a generic term for steel with low carbon content which makes it easy to weld, form, and machine. If you're looking for a knife blade material, you need either a stainless steel or a high carbon steel which is not at all weldable. The more carbon in steel, the better it responds to heat treatment like hardening, tempering, etc. Plus, the high carbon steel will hold an edge better. Hope this helped.

Q: How are steel coils heat treated?: Steel coils are typically heat treated by subjecting them to controlled heating and cooling processes. This involves heating the coils to a specific temperature, holding them at that temperature for a defined period, and then slowly cooling them. The heat treatment process helps to improve the mechanical properties of the steel, such as its strength and hardness, by altering its microstructure.

Q: How are steel coils inspected for thickness and width accuracy?: Steel coils are inspected for thickness and width accuracy using various methods. One common method is using non-contact laser or ultrasonic sensors that scan the surface of the coil to measure its thickness and width. These sensors provide accurate measurements without physically touching the coil. Additionally, manual measurements can be taken using calipers or micrometers to verify the accuracy of the coil's dimensions. Overall, a combination of non-contact sensors and manual measurements ensure that steel coils meet the required thickness and width specifications.

Q: i recently got an industrial piercing and instead of getting pierced with a metal bar i have a PTFE bar .. i eventually want to put in a metal bar but what kind do i get? whats the difference between a surgical steel and titanium bar?thanks: 316L steel is the most basic metal used in body jewelry. It is the basic requirement of metal to be used in initial piercings and for healing. There are better grades but usually they cost more as well. For most people this grade of steel works just fine. Titanium is usually preferred over steel because it contains no nickel and it weighs almost 50% less than steel. Titanium can come in plain polish which looks just like steel AND it can come in a variety of colors (but NOT red or black). Titanium is super for people with sensitive skin to steel. It does cost a little more but is well worth it.

Q: Can steel coils be bent or shaped?: Yes, steel coils can be bent or shaped due to their flexibility and malleability.

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: I was wondering whether anyone knew if painted steels rusts at the same speed as steel that isn't painted. Also, does steel rust quicker than aluminium?Thank you: If the steel is properly prepped when painted, then it would last a long time before any rust or corrosion sets in. This still all depends if the item is subjected to water or salt and if the item you painted is not scratched in any way, once exposed from the paint, the rust will begin rapidly. As far as aluminum, no it will not rust, but you do get aluminum oxidation. It gets a white flakey appearance when it begins to oxidize. Now if you are thinking of painting the rims on a car, i recommend scuffing the rim, priming it, lightly sanding and then paint to the color of choice and for the final touch apply a clear coat on the rims to help avoid the rusting. Use a paint such as rustoleum to prolong the effects of rust settling in. good luck..... good luck.....
