Q:What does Blue Steel meen?
Reference is to a gun which is typically the process of Bluing the steel of the guns metal parts.
Q:Is Galvanized Steel a raw material?
The term 'raw material' usually refers to the components that a manufacturer must purchase in order to make a product. For example, an automotive manufacturer would purchase galvanized steel from a steel supplier, and would consider galvanized steel to be a raw material for his production process. However, I suspect that your instructor means to imply something slightly different. I suspect that the question is really asking what are the 'primary' or 'fundamental' components of a paper clip. In that case, the definition goes beyond what must the paper clip manufacturer purchase, and is really asking what fundamental physical elements go into the manufacture of paper clips. So the answer would be iron, carbon, oxygen, etc, because those are the elements that are required to produce steel. By the way, I'm not sure that paper clips are made from galvanized steel - or for that matter, even from steel. But that's another question.
Q:is 440 stainless steel good for throwing knives?
For throwing knives, 440 isn’t necessarily a bad choice. Does it list whether it is 440c or 440b? That matters somewhat. The advantages of 440 Stainless is that it’s relatively hard (for a stainless), it resists rust significantly, and it’s not so hard that it would shatter or break. On the down side 440 is notorious for not taking or holding an edge, but for a throwing knife, that’s probably not much of an issue. If you’re looking for something to train with, you’re fine here. It’s plenty of steel enough to stick in wood or other targets. Odds are it won't bend if you slam it into some wood. If it lands on concrete, eh, it's going to scratch and all that jazz, and it might hurt the tip if it hits first, but as has been said, you can use a file or grinder to get the tip back.
Q:physics compression:Steel rod?
You need to calculate the stress on the rod and compare this with the mechanical properties of the steel. It would help if you were given more info. You will need to know something about the steel such as the yeild stress and E, the modulus of elasticity. The value of E is about the same for a wide range of steels. So long as the applied stress is below the yield stress, the strain is all elastic and is calculated from E. The real answer is that you can not answer this question since you do not know what the temperature is. Given the applied load, the change in length will be much different at room temperature than at 1500C.
Q:Brass or steel cases through an AR-15?
What the person that told you that failed to mention is that steel ammunition is slightly less malleable than brass so it does not expand as tight to the chamber walls to seal the gap from expanding gasses. This causes a little bit of carbon to build up over time and can make brass ammunition get stuck. The simple solution is to shoot brass before steel, or to clean the chamber really good after firing steel ammunition.
Q:What are black steel pipes made of ?
Black Steel or ductile steel pipes are made from scrap for the most part. Galvanized pipes are made from new raw materials and are electroplated to resist rust.
Q:Angular Velocity of a Steel Ball after a 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:What's the process of making steel?
I believe you are asking about two vastly different processes. This is science so, if you want a specific answer, you have to ask specific questions. VERY Basically... 1) Pig iron production works by melting iron and pouring it into molds that produce ingots called pigs. 2) fraction distillation separates different substances (typically starting in liquid form) by controlled heating so, since different substances boil at different temperatures, the vapors can be captured selectively.
Q:Casting Stainless Steel?
You have 2 options. Sand casting or investment casting. Stainless steel can be cast with either of these methods. In either case a model or pattern will have to be created. For sand casting the pattern is all that is needed to go to casting. For investment casting the pattern is used to make a wax casting, which is then coated with the investment. The wax is burned out and the metal is then poured into the cavity. If you are making just 1 or 2 pieces you can have waxes machined. This saves the intermediate step Depending on the size machining may still be your best option. Especially if you want just 1 part.
Q:keeping a stainless steel stove clean and shiney?
How grimy is your range? I actually have a stainless range and all I do is discover a soapy sponge on it, with dish cleansing soap. I get rid of each and all of the knobs and burners approximately as quickly as a week (and every time I fry something and splatter oil everywhere, yet i attempt to disguise issues with foil as quickly as I fry to sidestep a multitude). It takes possibly 5 minutes to scrub my range because I shop it clean and not in any respect, ever use it if it has spills on it. i've got found out via the years to wipe issues up right now, or the spills get baked on and become very confusing to get rid of. My range is electrical powered, so I take off the electrical powered burners and gently wash those with a soapy sponge too (I carry them and rub the soapy sponge on them, then carry them below the faucet to rinse, without getting the plug in factor section moist). My range continues to be very clean this way, and that i take advantage of the rougher side of a non-scratch sponge for something that desires some scrubbing. in the experience that your range has undesirable stains caught on it, you ought to use very, very advantageous metallic wool on it. An SOS pad will paintings, do in basic terms no longer rub too problematic or you will take off the shine from the range. SOS pads are ok on each and all of the immaculate areas of the range. whilst completed washing it, take a humid dish towel and wipe each and all of the cleansing soap off, then dry the range and it will seem large.
