Q:I bought my Gerber Scout for 29 bucks at the local Walmart a couple months ago, and so far it's performed better than any of my previous knives (a couple of low quality Bucks, and a Winchester). However, my friend just bought a 50 dollar Buck knife and I absolutely love it, so I'm debating trading mine in and pitching in a bit of cash for the same kind.What troubles me is the fact that everybody seems to be bashing 440A steel. I hear a lot of bad things about it; how it is soft, chips easy, dull quickly, etc. How bad is 440A steel really, and would it be worth trading in my Gerber plus about 30 cash for a Buck Vantage Pro? Apparently the Vantage Pro uses S30V steel, so is it really that big of an upgrade, from 440A to S30V? Thank you.
Its the standard for most knives and its the easiest to sharpen, I have a couple 440 steel knives and they have never failed me, my oldest one is 11 years old and I have stabbed multiple people(in self defense, cut open backpacks, seat belts, fishing string, limes, thin rope, jeans, jackets, pockets, seats, popped tires, moved hot charcoal and other stuff, it just has to be sharpened every now and then. Although I really like carbon knives like KA-BAR's those are amazing and are the only fixed blade knife I would ever buy.
Q:Suppose that the hardness of steel is uniformly distributed, taking on values between 50 and 80 on the Rockwell B scale.Compute the probability that the hardness of a randomly selected steel specimen is less than 60. a..462b..333c..500d.2e..750 Question 8 Refer to question 7. Compute the probability that the hardness of a randomly selected steel specimen is between 70 and 75.a..167b..500c..063d..100e..
Suppose that the hardness of steel is uniformly distributed, taking on values between 50 and 80 on the Rockwell B scale. That would be... f(x) = 1/(80 - 50), 50 ≤ x ≤ 80 . . . . . 0 elsewhere Consider this following problem.. Compute the probability that the hardness of a randomly selected steel specimen is less than 60. Here, we have... P(x 60) Oh! Know that the mean and the standard deviation of the uniform distribution function are... ? = (a + b)/2 σ = (a - b)?/12 You should get... ? = 65 σ = 75 Now... P(z (60 - 65)/75) = P(z -0.07) Hence, you should get around 0.462. Good luck!
Q:steel of beam has been rusted ,how can i repair it?
The rust needs to be removed by what ever means works best for your situation.. Often a twisted wire wheel on a 4 1/2 angle grinder works quickly... a hand wire brush may work well for you, or just plain sandpaper and a LOT of elbow grease (hard work) will remove the rust. From there, a coat of primer paint made for steel. Any hardware store in your area would have such a primer, in quart cans or spray cans. Once that is dry (a good 24 hours for most formulations), you can spray or brush paint the beam most any color you wish.. I've had very good luck with acrylic enamel paints for such projects.. IF your steel is badly pitted, you should consider getting it inspected to insure it will still hold up or support what ever it was installed to do. If you want a smooth finish, once the rust removal is done, you can fill in the dips and pock marks with an auto body filler (Bondo is one brand name)... It comes in 2 parts (the main filler and a hardener) that are mixed well and used to fill in the holes and divits with a plastic spreader.. Once hard (in a few minutes with most brands of filler), sanding with sandpaper and a sanding block will smooth out the finish very nicely. From there, the same primer mentioned above and paint will finish up your project... Hope this helps some... Good Luck!
Q:I have two theories, which one's correct?My book says that steel is made up of 98% iron and 2% carbon.98% of iron's molar mass (55.85 g/mol) is 54.733.2% of carbon's molar mass (12.01 g/mol) is .2402.If you add them up that gives you that steel has a molar mass of 54.97 g/mol.However, steel's chemical formula is Fe(3)CThat would make it's molar mass 179.56 g/mol.( Because 3(55.85) + 12.01 = 179.56 )Which one is correct?
Steel is an alloy - a mixture not a compound; it doesn't have a chemical formula. Only elements and compounds have molecular weights, not mixtures that aren't composed of a uniform molecule, so neither answer is correct.
Q:I'm a hiker and cook on a camp fire with a canteen cup. So which would be a better material for cooking on a campfire with, aluminum or stainless steel?
Direct fire will kind of ruin stainless steel. I've screwed up several stainless steel pans cooking directly on a campfire. I have to agree with wildflower the best route by far in a small cast iron pan. They are pretty heavy though.
Q:exactly what is the differance between strontuim steel and stainless steel any differances as far as hardness .... need help.
Strontium steel is created by soaking a mild steel in strontium chromate, which has a pH of about 4 or 5, roughly the equivalent of acid rain. Chromate affects the cathodic reaction, with reduction of Cr6+ to Cr3+, and the surface film was composed of magnetite and hydrated chromium hydroxide. The Strontium is a radioactive isotope. The acid bath permeates the mild steel causing it to become mildly radioactive. Simular to oil imprengation of brass and other metals. Strontium Steel has a very high value of inhibition. However due to it's radioactive properties it is not a commonly used or manufactured material. As for where to actually obtain Strontium steel dowels. I have no idea i would speculate that you would have to purchase the raw stock and have it machined into a dowel for you.
Q:I bought a steel pendant on eBay, but it turned out to be too shiny.I've read on a couple forums that if I leave it soaked in urine for 2 days, it will get duller.Now, if it really does get duller, will the pendant get rusty afterwards?So is the shiny surface the only thing that prevents it from rusting?Any simple, non-urine ideas on how to make it duller are welcome too.Thanks!
Stainless steel will rust under proper conditions. I live on a boat on salt water, trust me. If the urine works it won't be prone to rusting any more than before. It's not the shine that inhibits rusting with stainless steel, it the % of carbon in the steel, compared to regular steel. IF the urine works it's because it is acidic (a mild acid). Wash it with a small brush and some baking soda to neutralize the acid when your done. A much stronger acid would be swimming pool acid. (Muriatic acid) but be careful you might test a spot with a Q tip on the back. If you try Muriatic acid it would take seconds.Then wash in baking soda water to remove all acid.. SS
Q:The hard industrial steels. If there's a bunch, what's a rough average? Also, what is is measured in?
Hrc Steel
Q:I'm wondering if steel casings are bad for a 1911. I know that an AK-47 will eat up steel casings all day long, but steel casings are bad for, and can be hard on an AR-15. I only have brass for my AR and that will never change. I'm curious as to how a 1911 fairs with steel casings. Is it bad for the gun or does it not matter? I'm asking because steel cased rounds seem to be the only readily available ammo these days. Thanks
steel casings go back to the early 1900's for 1911's. Most guns were always able to handle them and most of that has carried on. I would think glocks are a no no for steel for longevity but in the caribbean we have mainly steel casings and that's all we use. the 1911 is probably the most popular hand gun down there. I own one, and FM. Over 1000 rounds so far in her between me and my dad (previous owner)
Q:I know that mild steel is more brittle than cast iron....but that is all.......please help??Thank you in advance......Ruby:D
Mild steel is iron that has had most of the carbon removed in an open hearth furnace or a Bessemer converter. It is mainly the carbon content that makes iron brittle (iron is brittle, not steel).
