mild steels will almost allways be corroded by HCl and H2SO4.  Depending on the pH and electric potential conditions different oxides and other iron ions will form, but it is very difficult to prevent the corrosion.  in addition, the oxides that will for are generally not adherent meaning they will not stick to the surface and protect the metal.\n\nthe bottom line is except for very rare conditions the steel will corrode and will be eventually completley destroyed, and i'm sure you can imagine what this will do to the properties.  to prevent this, just use an appropriate stainless steel alloy

Go to azom.com they have info on both 304, 316 and many other metals.\n\nIn a nut shell, 316 stainless steels are more corrosion resistant than 304 stainless steels

That depends on the alloy of steel you are talking about. The term alloy is almost always used incorrectly these days, especially amongst bicyclists. They use the term to mean aluminum. What the term alloy really means is a mixture of metals, any kind of metals. Almost all metal used today is a mixture and therefore an alloy.\n\nMost steel has other metals added to tune its properties, like strength, corrosion resistance, or ease of fabrication. Steel is just the element iron that has been processed to control the amount of carbon. Iron, out of the ground, melts at around 1510 degrees C (2750°F). Steel often melts at around 1370 degrees C (2500°F).

There is a HUGE amount of infomation on metallurgy out there, but if you want an interesting search, try searching out why the HUBBLE Space Telescope failed - there was some deformed metal and the reason the optics tests passed before launch is an interesting story about materials, optics and people.\n\nI'm a metallurgist, and of all the exotic materials it turns out steel has the greatest range of properties (from annealed iron all the way up to ball bearing steel and stainless).  Titanium is interesting stuff (good for corrosion and medium temps (500°F-1000°F), but aluminum can have the highest density-to-strength ratio.  Research on how tungsten filaments are made is interesting too.  \n\nMark Twain said that a metallurgy student would learn more making his own pocket knife by digging the ore out of the ground, refining it into steel, and fabricating the knife than he would by book learning - do you have a passion you're particularly interesting in?  Learning about something you're interested in is effortless.\n\nAnother optics subject of interest is what is currently going on in semiconductor photolithography - they are reaching the limits of what can be done with light and refractive materials (CaF lenses) and immersion lithography (see link below).

Ferrous metals (iron/steel) rust and non-ferrous (aluminum/copper) metals oxidize.\nBoth are chemical reactions and effects of oxygen and moisture present in the atmosphere.\nBTW, ferrous metals are magnetic, non-ferrous metals aren't. Try it.

Can be quenched with water?

2-all of the microstructure of it is a structure named Perlit(consists of ferit and cemantite , later is a hard phase) . all of matterial that is very hard they are brittle unless we treat them.3- all of cast iron is not britle we hane ductile cast iron but generally they are britle because of cemantite phase.4- it is very hard then is brittle.5- because when tempering harsness decreases.6- it deponds on final application.1-all of alloys that are weak they are ductile . we need smaller force to reform them.hope they are useful for you.

Aluminum will oxidize, but the aluminum oxide forms a coating over the remaining aluminum that prevents further corrosion.\n\nBy contrast, iron oxide (better known as rust) will not form such a coating, it will warp and crumble and expose more iron to rust.

Titanium is used for a lot of things because of its unique properties.  For structural things, like aircraft parts or bicycle frames, it is usually alloyed with aluminum and vanadium because it is far too brittle in its pure form.  Even alloyed, titanium will not bend much before breaking (unlike mild steel or aluminum, which are very ductile).  This one of the reasons surgeons use it for bone pins and the like.  The extreme hardness and lack of ductility are common to most metals that have the same face centered hexagonal crystal structure (the arrangement of atoms in bulk material) more ductile metals tend to have cubic crystal structures.  \nIt is stronger than steel by weight, but not necessarily by volume, though it beats aluminum on both counts.  \n\nOne of the reasons you don't see it in more places is that it is very expensive to refine and work with.  Casting it requires much higher temperatures than steel and it is very sensitive to impurities so it is difficult to weld.  It is very hard so it is difficult to machine or cold-form.

You should find that under the ASTM Manual for steel. Your engineering department should have a copy, otherwise try finding it on line.

If the spheres are of same volume, their apparent loss of mass will be the same.\n\nIf the spheres are of same mass, Aluminium sphere's apparent loss of mass will be more.

Paramagnetic materials like Aluminum have magnetic properties, but cannot sustain a permanent dipole moment alignment. Hence it qualifies as a candidate for your question.\n\nAlso ferromagnetic materials (common ones are Cobalt, Iron, and Nickel) above their associated curie temperatures behave the same way. No permanent magnetization.

Aluminium or aluminum is the chemical element in the periodic table that has the symbol Al and atomic number 13. It is a silvery and ductile member of the poor metal group of chemical elements. Aluminium is found primarily as the ore bauxite and is remarkable for its resistance to corrosion (due to the phenomenon of passivation) and its light weight. Aluminium is used in many industries to make millions of different products and is very important to the world economy. Structural components made from aluminium and its alloys are vital to the aerospace industry and very important in other areas of transportation and building in which light weight, durability, and strength are needed.\n\nAluminium is a soft and lightweight metal with a dull silvery appearance, due to a thin layer of oxidation that forms quickly when it is exposed to air. Aluminium is nontoxic (as the metal), non-magnetic, and non-sparking. Pure aluminium has a tensile strength of about 49 megapascals (MPa) and 400 MPa if it is formed into an alloy. Aluminium is about one-third as dense as steel or copper; is malleable, ductile, and easily machined and cast; and has excellent corrosion resistance and durability due to the protective oxide layer. Aluminium mirror finish has the highest reflectance of any metal in the 200-400 nm (UV) , and the 3000-10000 nm (far IR) regions, while in the 400-700 nm visible range it is slightly outdone by silver, and in the 700-3000 (near IR) by silver, gold and copper. It is the second most malleable metal (after gold) and the sixth most ductile. Aluminium is a good heat conductor which is why it is used to make saucepans.

Hi. As with most things it depends on the cost of manufacture. : http://www.steelonthenet.com/commodity_prices.html

Depends on the crystal structure of the alloy they constitute
