- Q: Can you reload spent casings if they are steel?
- Let me break it down for you. 1) There are two kinds of priming in current use these days -- you cannot tell from the outside which primer it is...only by looking inside the casing. If the casing has a single center primer hole, it is Boxer primed. If the casing has multiple primer holes, none of which is center, it is Berdan primed. Berdan and Boxer are the names of men who designed the priming systems.
- Q: Hi I was thinking about buying this knife, but i wasn't sure if it was good because it's stainless steel.
- This isn't really a question for this section, but I'm still happy to help out since I'm a big cutlery nerd as well. One thing to look out for when buying a knife is a lack of specifics on what steel is being used. High Carbon Stainless Steel doesn't tell you what the steel is, just what it MIGHT be. Chances are it's something along the lines of 420HC or 440A, both of which are softer steels. They aren't the worst steels around, but they are very quick to dull. You'd be better off looking at the Balisongs of Benchmade. They'll cost more, but you'll know that you're getting something made with quality materials and that won't break on you. And if it does break for some odd reason, Benchmade's warranty and customer service are both fantastic. Although if a more questionable knife is okay with you as long as the price isn't too high, then at least 420HC and 440A aren't too brittle and will take a decent edge even though they'll dull quickly. As for whether stainless steel is good for a knife or not, that depends on the type of stainless steel and what you're going to use the knife for. Many stainless steels are more brittle than a carbon steel, so high carbon stainless steels are a bit more likely to rust but a little tougher as well. In a butterfly knife, a steel like that is a good way to go, although the steels used by Benchmade, as I mentioned, are of a much better quality.
- Q: What are the different types of steel coil welding methods?
- There are three main types of steel coil welding methods: continuous welding, spot welding, and seam welding. Continuous welding involves joining the edges of steel coils continuously, creating a seamless weld. Spot welding involves applying a series of localized welds at regular intervals along the coil edges. Seam welding is a combination of continuous and spot welding, where a continuous weld is created by intermittent spot welds.
- Q: What are the main factors that affect the corrosion resistance of steel coils?
- The main factors that affect the corrosion resistance of steel coils include the composition and purity of the steel, the presence of alloying elements, the surface condition and finish of the coils, the exposure to moisture and corrosive substances, and the protective coatings or treatments applied to the steel.
- Q: I don't know why but I'm having a VERY difficult time finding the melting point of 1008 steel.
- It is still the same for 1008 steel. Go to the bottom and see the listing of the grades it covers. Since the only difference between the 1006 and 1008 steel is a few micro amounts of alloys and by far the greatest majority or main component is iron (99%), as a general melt temperature , 2750 F is the melt temperature at which the other alloys are added to the charge to fine tune the mix. Just like adding salt to distilled water actually lowers the boiling point of water, adding alloys to iron decreases the melting point of iron. The iron melts at 2800F, but once alloys to make the 1008 grade are added, it decreases melt temp to 2750F. Since the melting point of pure iron is 2800F, the temperature is actually decreased by adding these impurities of alloys. These alloys are tested while the mix is starting to come down from a pure melt, steel is sampled. and then alloys below are checked and added to make the 1008 steel. The steel is maintained at 2750 F so that the less volatile alloys don't boil off before combining with steel.

- Q: How are steel coils inspected for camber using laser profiling?
- The inspection of steel coils for camber involves the use of laser profiling, a measurement technique that does not require physical contact. Laser profiling works by emitting a laser beam onto the surface of the steel coil, creating a detailed profile of its surface. To detect camber, the laser profiling system scans the entire length and width of the coil, capturing data points at regular intervals. These data points are then analyzed to determine the deviation from a straight line, indicating the presence of camber. During the inspection process, the measured profile of the steel coil is compared to a reference profile, which represents an ideal or straight surface. The deviation between the measured profile and the reference profile is calculated, and if it exceeds a predetermined threshold, the coil is flagged as having camber. The use of laser profiling offers several advantages for camber inspection of steel coils. Firstly, it eliminates the need for physical contact, reducing the risk of damage. Additionally, laser profiling is highly accurate, capable of detecting even small deviations in the coil's surface. This ensures reliable detection of camber, allowing for necessary corrective actions to be taken. Overall, laser profiling is an efficient and accurate method for inspecting steel coils for camber. It enables manufacturers to maintain high-quality standards and deliver reliable products to customers.
- Q: Which movie is better and why?I say Man of Steel!
- Captain America: The First Avenger -- Mostly because it was a rousing, entertaining, old-school adventure film, plus it was true to the character of Steve Rogers/Captain America. Man of Steel, IMO, had a poor script, tinkered way too much with one of the great superhero origin stories and was not at all true to the character. Historically Superman has always been a symbol of heroism, proud, strong, beaming. But what we got in that movie was an utterly cheerless, dour automaton devoid of any kind of charisma or presence. I don't know who that boring, depressed dude who looked like Superman was in that movie, but he most certainly wasn't Superman.
- Q: How are steel coils used in the manufacturing of industrial valves?
- Steel coils are used in the manufacturing of industrial valves as they provide the necessary raw material for creating valve bodies, stems, and other components. The coils are shaped, cut, and formed into different valve parts, ensuring strength and durability. These steel components are then assembled, welded, and machined to create fully functional industrial valves used in various applications such as oil and gas, chemical processing, and water treatment industries.
- Q: What are the different methods of coil joining for steel coils?
- There are several different methods of coil joining for steel coils, including welding, laser welding, stapling, and adhesive bonding.
- Q: How are steel coils used in the production of electrical switches?
- Steel coils are used in the production of electrical switches as the core component of electromagnetic relays. When an electric current passes through the coil, it generates a magnetic field which attracts or repels a metal armature, thus opening or closing the electrical circuit. This mechanism allows electrical switches to control the flow of electricity in various applications.
