- Q:Well actually I was just wondering why people were bashing on stainless so much for katanas. I heard that they don't hold their edge as well as carbon steel blades or Damascus steel. So what makes it so inferior to carbon or other types of steels?
- No real swords are made of stainless steel. Its is simply a poor material for swords. Only kitchen knives that are required to be easy to clean and corrosion resistant are made of stainless. Adding chromium and other trace elements adds nothing to the ability to cut well or hold an edge. It is not strong enough to withstand the forces involved, being too brittle and lacking in toughness. Those decorative swords are not really swords at all.... rather they are sword shaped objects.
- Q:How are steel coils inspected for thickness variations?
- Steel coils are inspected for thickness variations using non-contact measurement techniques such as laser or ultrasonic sensors. These sensors are capable of accurately detecting and measuring the thickness of the steel coils at various points along their length. The collected data is then analyzed to identify any variations in thickness and ensure the quality and consistency of the steel coils.
- Q:How are steel coils protected from extreme weather conditions?
- Steel coils are typically protected from extreme weather conditions using various methods such as covering them with waterproof wraps, storing them in climate-controlled warehouses, or applying anti-corrosion coatings. These measures ensure that the coils are shielded from moisture, temperature fluctuations, and other environmental factors that could potentially damage or degrade the steel.
- Q:I'm putting a bathroom in my basement. I'm an Ironworker btw. I wanted to go with steel studs due to the fact that they are light, and I won't have a big mess. I live in the Chicago area and they should be easy to find. Here is my question. Are they not being used anymore? I ordered 100 studs from Lowe's but they didn't have track. The delivery guy was a retired Carpenter and he told me that I got all the studs they had, they no longer stock steel studs, and they don't have track. Am I missing something? Menards didn't have track either.
- Ask a Carpenter friend where you can buy metal studs. There should be a large drywall supplier somewhere close to your area - they usually also stock metal studs and ceiling grid that sort of all goes together for contractors. You will have a choice of 20 or 25 gauge studs track. 25 gauge is pretty flimsy so I suggest using 20 gauge. Get a small box of tek screws to attach studs to track. Also get some self drilling drywall screws 1+5/8 for 5/8 thick gyp bd. or 1+1/4 for 1/2 gyp bd. I would also buy MR drywall (moisture resistant) for any work in a basement. Another tip : Buy some 1x4 composite trim boards to use for your bottom plate. Clean the slab good where you plates will go, then use some Liquid Nails hd and glue your plates down to the slab. That way you won't be drilling holes in the slab that could allow water to seep up through them. The composite trim will not wick moisture and it will keep your metal studs up off the floor should you ever have a water problem in the bathroom. Keep your drywall up off the floor about 1/2 by laying a scrap pc. of drywall against the plate before you hang the board. Allow enough room to line the perimeter of your door frame with 2x 4 vs. metal stud. It makes it easier installing the door and trim.
- Q:What are the common defects in steel coil finishes?
- Steel coil finishes can be affected by various defects that can impact both their appearance and functionality. Before using or selling the coil, these defects may need to be addressed. One common defect is coil breaks, where the steel strip breaks during winding or unwinding. If not dealt with, this defect can cause a discontinuity in the coil's surface and potentially lead to further damage. Another defect is edge wave, which refers to a distortion or waviness at the edges of the coil. This can occur during the rolling or cooling process and can affect the coil's flatness and uniformity. Corrosion is another issue that can arise if steel coils are not properly protected or stored. This can result in rust and degradation of the steel, impacting its strength and appearance. Streaks and stains can appear on the surface of steel coils due to improper cleaning or contamination during production. These defects can affect the aesthetic appearance of the steel and may need to be addressed before use. Scratches and dents can occur during handling, transportation, or storage of steel coils. These defects can impact the flatness and surface quality of the steel and may require repairs or adjustments. If a coating or paint is applied to the steel coil, several defects can arise, including blistering, peeling, or uneven application. These coating defects can affect the durability and appearance of the steel. It's important to note that the severity of these defects can vary, and different methods of repair or mitigation may be needed. Regular inspections and quality control measures can help to identify and address these defects before they become more significant issues.
- Q:How are steel coils processed and shaped into different products?
- Steel coils are processed and shaped into different products through a series of manufacturing techniques. First, the coils are uncoiled and straightened to remove any deformities. Then, they go through processes like cutting, slitting, or shearing to achieve the desired width and length. Next, the steel is shaped using techniques like rolling, bending, or stamping to create specific profiles, such as sheets, plates, or tubes. Additionally, various heat treatments and surface finishes can be applied to enhance the strength, durability, and appearance of the steel products. Overall, a combination of mechanical, thermal, and chemical processes is employed to transform steel coils into the wide range of products we see in industries like construction, automotive, and manufacturing.
- Q:what happened to all the steel beams from the WTC buildings? did anyone do any forensic analysisof any of the steel?
- Some of the steel was recycled for sale to other countries where they aren't so picky about reusing building materials. NIST had 200 pieces of the steel for their investigation, which they returned last year. This was covered in the press. The rest of the steel was held at JFK international airport's Hangar 17. Much of it will be placed/has been placed in the new museum beneath the Memorial at the WTC site. Thousands of pieces are being given out for 9/11 memorials all over the world. Just about every day you read in the newspaper about another piece going here or there to this city or that city. Yes, a lot of the steel was tested for a number of chemical compounds. It had to be for safety reasons before storing it and giving it out. Depending upon what countries the recycled beams were sent to and their rules, it was sometimes tested at the ports of entry over there, as well.
- Q:A 100 kg solid steel ball with a radius of 5 m is being spun on ice with an angular velocity of 5 rev/s pointed into the ice (clockwise rotation when viewed from above).A student shoots a 10 kg marble at the steel ball. The marble hits the ball along its side as shown with an initial velocity of 5 m/s to the left. If, right after the collision, the final velocity of the marble is 2.5 m/s to the left, what is the angular velocity of the steel ball after the collision?
- You need to do conservation of angular momentum about the steel ball's axis. Angular momentum = I.ω The steel ball's initial ω = 5 rev/s = 5*2pi rad/s = 31.4 rad/s The steel ball's moment of inertia I = (2/5)*m*r^2 = 40*25 kg.m^2 = 1000 kg.m^2 The marble's initial ω = v / r where r is the perpendicular distance from the steel ball's axis You need to look at the diagram for this. The marble's I about the steel ball's axis is I = m*r^2 where r is the same as above. (marble is treated as a point mass). Then work out the total initial ang. momentum = final ang. momentum and solve for ω...
- Q:for my engineering project I have been asked to design a method of suspending a TV of weight 14Kg from a gantry, the TV must be 5m below the gantry. My team have decided to use as a suspension method a steel cylinder of outer diameter of 10cm and an inner diameter of 8, however we now need to work out both the max stress and strain and the actual stress and strain. and help would be useful
- In most engineering calculations we have to make some assumptions about ideal behavior of a material otherwise we would not be able to simplify our equations to manageable sizes. Your steel cylinder (which I'll call a pipe) is made of a certain type of steel. That steel type has property tolerances listed in a steel manual to help you know about your steel before you begin. You'll need to know the cross-sectional area of the pipe and the weight of the TV to determine an average stress on the pipe. Obviously the weight of the TV is the force it generates. The force is its mass x gravitational acceleration. Since we typically think of steel as an elastic material, we think of it stretching like a rubber band or a spring. You pull it down with a TV and it deflects a certain amount, and will return to its original length when the TV is removed. It is typical to assume that all steel, regardless of its strength, has the same value for this elastic property. It is commonly referred to as the elastic modulus. This value will help you determine what type of strain occurs under what type of stress. So, once you have the stress, you can get the strain by using the elastic modulus. Once you have the strain you can determine the deflection based on the pipe length. Having the steel properties will help you determine how close your TV comes to stressing the pipe to its yield stress. If you reach a yield stress, your steel will deflect, but when you take the TV off it will not return to its original shape. I hope I've helped outline some of the things you'll need to do for the project, I tried not to give away specifics so that you can actually engage your brain around the project. Enjoy, learn a lot, and realize that this skill could easily turn into a career where you are designing projects that when done correctly save people's lives every day of the year.
- Q:i have noticed in guns, and artillery the shell casings are always made out of brass. brass is expensive, weaker and dosnt look as good as steel. so why use it for casings? i am aware some of the case must be deformed. but just a small brass percussion cap could be used just for that and steel for the rest. whats going on?
- Expansion and more resistant to rust. Besides, steel cased ammo is made in East Eur..abia in all kinds of calibers but many people complain about it not being able to expand or that the steel wears out the extractor faster (not true), then they go and buy some.
