Q:Is 30CrNiMo8 a kind of high alloy STEEL?
Pretty sure it's low alloy steel, it's harder to smelt as it can contain up to 50% of other elements.
Q:Which is stronger, Wood or Steel?
steel bridges that have been made of wood lasted way longer than steel bridges NOT true. Why do you think bridges are made from steel or concrete, and not wood? wood rots and splinters and doesn't last more than 10 years when exposed to the weather. .
Q:Can stainless steel cut well?
There are many kinds of stainless steel. 440c, 420j, ATS34, and so on. Cold steel uses 420 type steels in several of their products. High carbon stainless steels cut well but edge retention is not very good but that also depends on the heat treating of the metal. I could go on all day but very, very basically stainless steels lack the shatter resistance necessary when stretched to great lengths. This is in part why other steels make far better swords. The stuff sold on QVC is just plain junk. Do not buy a stainless steel sword. A blade made of 440S means it belongs hung on a wall...
Q:Guns, Germs, and Steel?
i dont really understand this question but if it means to how it was before then it was absent because the native americans were not into technology so they obviously had no guns created that was something that they had traded to get from europe as for the germs i ddo not know about thta really except for if it means that common disease and one of the diseases most used in history books is malaysa from mosquitos but when they had traded with europe they got all sorts of diseases now for steel the only reason i remember them traveling for is for gold and i dont remember them ever looking for it until 13 colonies were established as you can see im not exactly sure about germs and steels but i know that the guns part is correct
Q:Damascus steel sword question?
There, the true Damascus is a region of spain, which is similar to getting swords made in Pakistan
Q:What is the weight of a molecule of steel?
Steel is an alloy consisting mostly of iron with a little Carbon thrown in. Steel is not a molecule, therefore, it does not have a molecular weight. Steel contains atoms of iron and carbon in a crystal lattice, along with various other alloying elements such as manganese, chromium, vanadium, and tungsten.
Q:Iron heavier than steel?
Steel is iron, with other things added that strengthen it and/or make it less rust liable. So, in general, steel is stronger than iron. In so far as the density, that depends on the steel alloy. Some are higher than iron, some lower. Remember there are hundreds of different steel alloys. edit: but the density is still close to that of iron. density steel 7750 to 8050 kg/m³ density iron 7870 kg/m³
Q:When did Chevrolet switch from wood spoke wheels to steel disk wheels?
Steel wheels were not available on the pickups until 1929. The cars had the options of steel disc or wood spoke wheels in the mid '20's. I'm pretty sure that '27 was the last year the wood wheels were available on passenger cars.
Q:Conductivity question for electricity through stainless steel?
I can only guess. I can't even tell if you are plating some other metal with copper OR if you are plating copper with some other metal. you state that you use the copper clamps only to confirm the current, but I don't see how that works. I suspect that the plating current actually goes through these clamps, so conductivity is very important. But, the conductivity of SS is about 1/5th that of copper, so that will definitely have an effect, and not a good one. .
Q:Runescape mithril vs. steel smithing?
i think steel would be better since there isn't a lot of mithril ore and it would take a lot of time to mine it and it will take also 4 coals to make a mith bar and 2 only for a steel bar
