- Q: I know that they have steel shot in smaller sized pellets....say, number 4 shot. I guess it's for waterfowl, etc.Do they make steel buckshot? If not, why not? Would the pellets be too heavy? Wouldn't they have excellent penetration ability?
- Steel shot is used for hunting migratory waterfoul. Since buckshot is inappropriate for waterfoul hunting , it is not manufactured. Steel is less dense than lead and for the purposes for which buckshot is appropriate, lead is permissable and is more efective. There is no need for steel buckshot.
- Q: Ok, lately I've been taking to making things out of stainless steel chain mallie rings. The problem is that when i make a bracelet or something, the area around the fastener always looks pretty bad. I'm thinking to have a friend who also does chain mallie finish the weave all the way around. This would make it look good but make it impossible to remove.Are there any long term problems with stainless steel on skin? I know some metals will change the color of the skin or make the skin absorb some of the metal. Is this something to worry about with stainless steel?
- Stainless steel contains both nickel and chromium. These two alloys are responsible for most of contact dermatitis in people. Some of my co-workers making steel had such bad reactions to chromium that they had to quit their jobs. Their skin was always inflamed. People don't react to finished stainless steel the same way because the alloys are bonded tightly in the heat treating process. But if you are grinding it and getting the dust on your skin, you could get a contact dermatitis if you are sensitive. I don't think it would absorb into your blood stream or do any long term damage to your skin. If you do get a reaction, you would have to cease your exposure or in a worse case scenario risk getting a body wide reaction like my coworkers. I would not worry about any exposure making rings out of stainless steel. After all, stainless steel is used in sugical implants and most people are fine.
- Q: - I'm considering doing my physics coursework on the uses of Mild Steel in skyscrapers and construction, would this be right? Some sources tell me mild steel is too weak, others say it is fine
- Mild steel doesn't really mean anything, technically. In today's world all steel is mild steel unless it's high carbon or alloy, which are mostly tool steels. You'll need to study steel much deeper than that to accomplish any real physics work relating to steel.

- Q: What is the role of steel coils in the manufacturing of bridges?
- Steel coils play a crucial role in the manufacturing of bridges as they are used as the primary material for constructing the structural components of the bridge, such as beams, columns, and girders. These coils are manufactured by rolling steel into flat strips, which are then wound into large coils. The high strength and durability of steel make it an ideal choice for bridge construction, as it can withstand heavy loads, extreme weather conditions, and provide long-lasting support. The coils are processed further to fabricate the required bridge components, ensuring the structural integrity and stability of the bridge.
- Q: What are the common quality issues with steel coils?
- Some common quality issues with steel coils include: 1. Surface defects: Steel coils may have surface defects such as scratches, pits, or rust spots. These defects can affect the appearance and smoothness of the final product and may also impact its performance. 2. Dimensional variations: Steel coils may exhibit dimensional variations, such as thickness variations, width variations, or length variations. These variations can lead to difficulties in processing the steel and may result in inconsistent product dimensions. 3. Mechanical properties: Steel coils may have variations in mechanical properties such as yield strength, tensile strength, or hardness. These variations can affect the strength and durability of the final product and may also impact its suitability for specific applications. 4. Coating issues: Steel coils that are coated or galvanized may experience issues with the coating, such as uneven coverage, peeling, or adhesion problems. These coating issues can result in reduced corrosion resistance and compromised aesthetics. 5. Internal defects: Steel coils may have internal defects such as inclusions, voids, or segregations. These defects can weaken the steel and may lead to failure or breakage during processing or use. 6. Edge issues: Steel coils may have edge defects, such as burrs, cracks, or uneven edges. These edge issues can affect the handling and processing of the steel and may also lead to problems during fabrication or assembly. 7. Coil set or camber: Steel coils may exhibit coil set or camber, which refers to the curvature or bowing of the coil. This can result in difficulties during processing and may lead to distorted or misaligned products. To ensure the quality of steel coils, manufacturers employ various quality control measures such as rigorous inspection, testing, and adherence to industry standards and specifications.
- Q: What are the different coil edge options?
- The different coil edge options include open coil, pocket coil, continuous coil, offset coil, and Bonnell coil.
- 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.
- Q: I've played guitar for years, now I want a steel guitar. As a beginner, to learn and experiment with, which one would be better for me?
- Pedal steel is very difficult. You need to co-ordinate both hands, both feet and both knees to play it effectively. Lap steel is a lot easier. I suppose it depends how much of a challenge you want. A good lap steel guitar is usually cheaper than a good pedal steel too, so that's another consideration to take into account.
