Q:Is 30CrNiMo8 a kind of high alloy STEEL?
Yes,30CrNiMo8 is a high grade alloy steel. *These steels generally contain higher carbon concentration (0.25%). As they are hardenable their mechanical properties can be tailored to specific needs by suitable adjustment of the annealing temperature. Finished products can be hardened to have a high surface hardness in combination with a tough and ductile core. The mechanical properties increase with increasing carbon concentration. Cr and Ni add additional improvements in properties. The Mn grades are a little cheaper. V and Mo add improved temperature resistance. The grades Cxx are developed for less stringent quality requirements but are cheaper.
Q:How is steel manufactured?
Abed is off on some of the details... Steel is, by definition, Fe-C. There are thousands of different steel alloys and I am not aware of a single one that is simpkly Fe-Ag. There are different processes but the chemistry is basically the same, converting the iron compounds we dig out of the ground into metallic iron. Iron is typically found as iron oxides or iron sulfides (not with a lot of carbon). We add carbon so the carbon takes the oxygen from the Fe atoms making Fe + CO/CO2. Research iron smelting, iron ore, reduction of iron oxide, these types of things. You will find plenty of information because this is one of the most important industrial processes humans have. Good luck
Q:What are the end uses of steel coil? galvanized steel coil?
Steel coil is the name given to thinner sheet steel when it is manufactured - it comes out of the machine and is formed into a coil for ease of handling storage and transportation. Thin sheet steel is used for plenty of stuff. It can be slit (cut) into thin strips as well as just cropped and used at one of the standard lengths x widths it leaves the mill. There is a big market for this material. It is used in many construction and engineering applications for things like ducting, boxes, gutters, down pipes, flashings, panels, car bodies etc., anything made of thin steel Galvanising is a flash coating of zinc which improves it's corrosion resitance. Cost wise it is a relatively cheap material. The chemical composition of steel varies, it is mostly iron but has various other elements added or present as impurities that change it's characteristics, depending on the end use. These additional elements can be selected to give better weld ability, hardness, tensile strength, corrosion resistance, flexibility and so on. In many applications excess of these chemicals is undesirable. For example sulphur and carbon are generally better at lower levels. The chemical composition data is contained in a material data sheet and expressed as a percentage of the chemical present and which gives the composition of a particular batch of steel, allowing it to be selected for particular applications and traced for quality assurance purposes. The list you have there shows presence and quantity of other elements in a particular batch of coil. The thickness is 0.23mm, quite thin.
Q:serious question! Dual-phase steel?
Dual Phase steels refers to a distinct group of alloys which are used for automotive bodies. These were developed to give improved deep drawing (for shaping) and strength while on the road. Most of the work was started at the same time in the 1970s as a response to the oil crisis (history repeats!) with SSAB in Europe, US Steel and British Steel leading the way. There are many variants of the dual phase alloys prefered by each of the auto manufacturers. The work on these steels led the way for TRIP (transformation induced plasticity) steels, rephosphorised steels and HSLA (high strength low alloy) steels. There is a distinction between these steels and duplex steels which typically refer to austenitic/ferrtic stainless steels. Also be aware that everyday low carbon steels with 0.1%-0.6% carbon will have a ferritic/pearlitic structure but are not considered to be dual phase So to summarise: Who - major steel companies worldwide When - from about 1973 onwards (up to around 1977 when the developments went in other directions) Where - Europe, USA and Japan (but I'm not sure who it was in Japan doing the work)

Q:Where do I need hot galvanized steel coils and color coated rolls?
In industrial or coastal areas, due to the influence of sulphur dioxide or salt in the air, the corrosion rate is accelerated and the service life is affected. In the rainy season, the coating has been soaked by rain for a long time, or the temperature is too large and easy to dew. It will be corroded quickly and the service life will be reduced. A building or building made of colored coated steel plates, often with a long service life when washed by rainwater, otherwise affected by sulfur dioxide, gas, salt, and dust. Therefore, in the design, if the roof slope is greater, the more difficult to accumulate dust and other dirt, the longer the service life; for those areas or parts that are not often washed by rain water, should be regularly washed with water.
Q:Is 100% carbon steel baking sheet safe?
This Site Might Help You. RE: Is 100% carbon steel baking sheet safe? Hi there! I just purchased two cookie sheets labeled as non-stick 100% carbon steel. I've never heard of carbon steel before, and I'm trying to be careful about not using certain products that are harmful to health such as aluminum and Teflon. Is this a safe metal choice for...
Q:Steel or nylon strings?
I urge you to read the answer from OU again and ignore the others - who obviously haven't got the first clue of what they're talking about. You pick the guitar for the type of music (and sound) you're after. You can play basically everything on a steel string that you can on a nylon string, plus a whole lot more... And no, a classical guitar is NOT easier to play than a well adjusted steel string with light strings - in fact it's the opposite. A classical guitar has a wide, flat fingerboard, something which makes chords much harder to play. Furhermore, the scale is longer (the scale is the distance between the nut and bridge - the length of the vibrating string if you will). This longer scale increase the distance between the fret (increasing the reach), and also increase the string tension. Finally, the action (string height) is larger on a classical/nylon string guitar as opposed to a steel string guitar which has been properly adjusted. Most guitars off the shelf have an inferior set up for a beginner, and this is why many have this funny idea that a steel string is much harder to play. You may also want to check out guitar body sizes (steel string) that is smaller than the large Jumbo or Dreadnought varieties. In essence, if you play classical music, or classical finger style guitar - choose a nylon string instrument. If not, then get a steel string and have it properly adjusted. Make sure you try out a lot of models as the necks, bodies, woods etc, differ a lot.
Q:A question about steel?
Your terms of strong and durable are not specific enough to know what you really need. Are you describing an application where you are using this as a spring or a structural support? Here is description home depot provides: Simpson Strong-Tie straps and plates join and reinforce joints with simple, versatile solutions for a wide range of connections. Available in many lengths, widths and thicknesses, YOur temcan be used on the wide or narrow face of lumber for light repairs or heavy-duty projects. Many straps are designed to be used back-to-back on a piece of lumber without fastener interference. A versatile, medium-duty strap for a variety of connections and splices Designed for use on the edge of 2x members, with a nailing pattern that reduces potential for splitting Install where plates or soles are cut, at wall intersections and as ridge ties 12 in. Length Made from 18-Gauge steel Stainless Steel offers extra corrosion resistance for exterior and treated-wood applications Install with 10d common nails If your application sounds like what they describe you should be fine. If it doesn't you may have trouble. As far as tempering your stainless I doubt you will be successful. If you take a magnet and it is not attracted to this strap, the strap is 304 SS. 304SS only gains strength through work hardening (making it thinner by rolling) Heat treating doesn't affect it.
Q:how can one go about melting and casting steel?
The other answers are correct. But don't attempt this unless you have lots of experience.
