what are the characteristics of iron / steel?
- Technically, this is known as ductility. a material which can be permanently bent and stretched is said to be ductile. Pure iron, when it lacks carbon and impurities like sulfur and phosphorus, is relatively soft, ductile, and weak. It's about as soft as brass. It can be stretched to about 50% of it's original length before it breaks. The amount a sample can be stretched without breaking is known as elongation. The key to steel is the addition of about 2 parts per thousand of carbon, or around 0.2%. This alters the crystal structure and makes steel much harder, stronger, and tougher, though it also becomes somewhat less ductile. Mild steel, with a low carbon content, has an elongation of around 30% Adding more carbon makes the steel yet stronger, but further reduces the elongation. Adding more than 2-3% carbon produces what is known as Cast Iron. Cast iron is brittle. It has virtually no ductility. It's pretty cheap to produce though.s
Can you use steel strings on a classical guitar?
- NO ! NO! NO! Do not put steel strings on a classical guitar!! The increased tension can actually damage the guitar by causing the top to warp and can eventually pull the bridge right off of the guitar! I have seen it happen more than once! Ignore the other post, they are wrong! Classical guitars are designed to use nylon strings only!s
is stainless steel and surgical steel the same?
- No it's not. I have worked in several different shops, selling body jewelry for years.-All inside malls- Every place I have worked (all specializing solely body jewelry) have used surgical steal. Not 100% on the grade for all items, but *most* were 316. Some items will be stainless or titanium. Typically stainless is cheaper and personally, I'd rather have a variety in metals because not everyone in the world is allergic to nickel, so why not have cheaper stainless items available for others? If you go up to any mall cart and tell them you have a nickel allergy, they should know to only show you surgical steal....unless they're idiots, which unfortunately some of them are. That being said, I have walked into tattoo shops and they have tried to charge me 35$ for a back and ball for my Monroe.....just a solid white gem.....The receptionist tried to argue with me on the quality of surgical steal, telling me, my products are lower grade and that's why she can charge me nearly 4x the amount. Well, I'm telling you guys, it's bullshit. I saw a display item in the original packaging and it was from the exact same company I ordered from. This was a very popular/redound shop in my area. They lie to push their product because they believe they can con you into buying it because they are the ones who pierced you (or in my case, sat at a counter and had me sign a few forms). It's just a bunch of **** guys...seriously, don't fall for it.s

what happen if carbon steel is exposed to an oxygen?
- Assuming the steel isn't actually melted, two things will happen. First, a layer of iron(ii) oxide, FeO will slowly develop on the surface, getting thicker over time. This layer is usually poorly bonded to the metal surface, it tends to flake off, exposing fresh metal. This is known as mill scale, it's also known as wustite which is the mineral term. Second, the surface of the steel will become decarburized, essentially becoming pure iron, not steel. The depth of the decarburized layer depends on the temperature, time, and the diffusivity of carbon in the steel at the given temp. This has some implications to engineering, in hot-rolling or forging of steel shapes for example. It's often the case that the stress and strain in a material is greatest at or near the surface. Therefore the weakened, decarburized layer at the surface may have a much greater detrimental effect on the steel's performance than might be expected. In a more specific example, die and tool steels depend on their carbon content for their strength and wear resistance, Therefore if such steels are heated in an oxidzing atmosphere, wear resistance is totally destroyed: The thin decarburized iron layer will be extremely soft and malleable.s
I am getting a benchmade mpr (m390 steel) and am unsure if it is a good knife look at the chart below?
- From what I read M390 is relatively wear resistant, with very high stain resistance and good toughness. It is quite hard to qualify steel as better than other steel because it depends on many factors. E.g. for a small folder designed for delicate cutting D2 at high hardness would perform better, but if the environment is corrosive, like saltwater then M390 would be better. I'm not so sure about using stainless steels in large chopping style knives, but I've seen M390 used for them as well. Obviously hardness had to be lowered, which reduces edge holding ability, especially at low angles. Overall, it's a good steel, but if it will outperform S30V or D2 or 154Cm depends on heat treatment and blade geometry, knife designed use, etc.s
Why is steel a stiff material?
- Steel is NOT stiff. In fact it is worldly accepted metals (steel is a metal) are not rigid in mechanical terms, and rigid means stiff. Steel easy to shape, but is strong and therefore hard to break. Thermosetting polymers (hard plastic) which is stiff, is in fact easy to break (weak) and also hard to reshape without changing its state (solid to liquid). Whoever told you steel is stiff is wrong and possible meant steel is strong, or you misheard/misunderstood.s
Will carbon steel knives stick to a magnetic knife strip?
- in the journey that your talking a pair of folding pocket knife, i think of that it particularly is truthfully six one way and a 0.5 dozen the different. i in my view do want stainless for my pocket knives. i do no longer elect to grease a knife to the degree i think carbon demands, in basic terms to then stick it my pocket to attraction to airborne dirt and dirt to the knife and oil to my pants. i'm the precise opposite on sheath knives inspite of the undeniable fact that. i admire 1095 carbon steel, undeniable side sheath knives. i will thrash on them difficult, and that i not often have important side issues. of direction, I require them to be lined with some form of powder coat or the like, as a results of fact they are able to rust, yet I do attempt and save them sparkling and dry whilst contained in the sheath, so they gained't pit the uncoated side. My motives for this sheath knife selection is multi-fold. First, those knives are merely much affordable. i do no longer spend $80 funds on a exterior sheath knife. i take advantage of the gadget too difficult to compliment to spend greater. i do no longer in basic terms like the greater classic stainless steels inclusive of AUS-8, 420HC, and 440C (to no longer point out the HORRENDOUS 440A) as a results of fact i think that the all else being equivalent, a stainless blade will bend earlier a carbon blade will injury. I additionally think of that carbon holds an side a minimum of besides, if not greater appropriate, than classic stainless, and it particularly is lots much less difficult to hone. i do no longer comprehend lots approximately those new laminates, different than the very difficult, yet no longer so hard. they look probable too brittle for my use. That, mixed with the very incontrovertible fact that they injury the bank, potential that I merely isn't pondering them.s
