- Q: What are the common coil tests performed for quality control?
- Some common coil tests performed for quality control include tension tests, bend tests, hardness tests, and dimensional checks. These tests help to ensure that the coils meet the required specifications and are of high quality.
- Q: How are steel coils used in the production of agricultural structures?
- Steel coils are used in the production of agricultural structures as they are the primary material for manufacturing various components like beams, columns, and trusses. These coils are typically shaped, cut, and welded to form the framework for buildings, barns, silos, and other agricultural structures. The strength and durability of steel make it an ideal choice, ensuring that the structures can withstand harsh weather conditions and support heavy loads, making them essential for the agricultural industry.
- Q: So i downloaded Broken Steel DLC for Fallout 3 for the 360. My guy is on the level where you have to activate the purifier and when i beat it. It was the normal ending that brought me back to the main menu. My friend said you have to find some guy to talk to but i don't think thats it. Please Help. P.S. i never got and conformation in-game about the download but its under the download sub menu at the main menu.
- Try Redownloading BS, That should work.
- Q: Guitar?I have a steel- string, but prefer nylon.:)
- As people say, nylon strings are (generally) for classical/spanish acoustic guitars - put steel on those and goodbye guitar; the neck will bow and can break.. On other guitars then steel is what you need - if you put nylon on you will have no sustain and tonality. A reasonable guide is the string winding mechanism of the classical guitar. Actually, steel is a pretty much generic term as lots of steel strings are now coated or wound with bronze or phosphor-bronze etc. Strings also come in different gauges or thicknesses depending on what you play. Lighter strings are best for finger-picking and heavier for strumming. Electric guitar strings tend to be strung lighter than acoustic. Finally, a guitar is built for a certain string gauge. If you put strings on that are too light then you may get fret buzz but if you put strings on that are too heavy you could bow the neck of the guitar.
- Q: Explain how you could make plastic sink and steel float?
- Plastics that are more dense than water will sink. For floating, you need to displace more water than you weight, so assuming steel is 10 times denser than water you will need to displace 10 times as much water weight as your steel occupies. This is easy for a wide hull ship (barge)
- Q: I am looking at website on google based on the terms structural steel fabrication and simply steel fabricationI know that there must be a difference between the two terms, but it seems that many website authors use the two terms interchangeably.Do you know the key differences between the two terms?
- Steel fabrication can include any kind of manufacture of steel. Structural steel is a narrow subset which would include, for example, I-beams and would not usually include stainless steel, sheet steel, rolled steel, etc.
- Q: Can steel coils be coated with electrically conductive materials?
- Yes, steel coils can be coated with electrically conductive materials.
- Q: I'm trying to make a corset but I can't find any steel boning in my area. Any clue as to what materials I could buy to to make my own bones, or anything that would work similarly?I know there are places to buy it online, but the cost of shipping makes it barely seem worth it.
- Don't try it. For two main reasons: 1. Corset boning is not just strips of flat steel; it is made from coiled high tension spring steel with clever metal ends to prevent tearing any fabric that comes into contact. You could try strips of hard wood such as teak, ash, oak. The risk is that the st rips will break when they bend around your corseted figure. Then they'll be dangerous and could puncture your skin. 2. Corset bones are there in the corset to support the fabric; not to exert any pressure on you for figure reduction. It is the cut of the fabric that produces the shape, but bones stop the fabric from crinkling, or gathering into your waist as the tension is applied. That is why commercial bones are specially made to be fairly lightweight, flexible in the right directions for your figure, and will not rust or otherwise deteriorate with wear or careful cleaning. So go for easiest you can get from the Net. That's my advice. OK?
- Q: Can i make holes in iron and steel with somekind of drill bit. All i have is metal drill bits. Mabey like 68 of them but i dont know wich one to use and if they will penetrate.
- Drills are used to make holes in steel all the time.
