Q:What grade of steel is best for a permanent magnet ?
The type of steel you require is Steel ( Iron + Carbon, mainly.),{many different types of steel } with a high Cobalt and Nickel content. These alloyed together give the best Permanent Magnets, mainly due to their own individual magnetic properties / characteristics being retained in the Alloy. All 3 metals can be magnetised by there own, but Cobalt is known to cause cancer. Nickel, is poisonous and can also cause sever Dermatitis and the destruction of skin tissue.But when alloyed together with Iron they are pretty harmless. Interesting thing is, All of these metals (in this case Elements) can share the same Mass Number ( 60 ). And yet are totally different in their other properties beside Magnetism. Cobalt - Samarium - alloys, create some of the worlds most powerful permanent magnets. And were used in medicine, But are now superseded by Neodymium magnets which are employed instead. Edit; What you could try is, mild steel which is widely available and easily found. . The steels mentioned above are pretty exclusive materials and I personally would not know how to test for their contents, of which they are made from. Soft Iron is good for making electro-magnets if you fancy a go at making one. .
Q:examples of some common alloy steels, what are their compositions and properties?
Steel is an alloy consisting mostly of iron, with a carbon content between 0.2% and 2.1% by weight, depending on the grade. Carbon is the most common alloying material for iron, but various other alloying elements are used, such as manganese, chromium, vanadium, and tungsten.[1] Carbon and other elements act as a hardening agent, preventing dislocations in the iron atom crystal lattice from sliding past one another. Varying the amount of alloying elements and form of their presence in the steel (solute elements, precipitated phase) controls qualities such as the hardness, ductility, and tensile strength of the resulting steel. Steel with increased carbon content can be made harder and stronger than iron, but is also less ductile. H.
Q:1943 Steel Pennies....?
I think they are worth about a pennie.
Q:.308 steel cased ammo in my remington 7400?
I shouldn't have an R-25, however probabilities are that when you use metal cased ammo in it you are going to sometimes handle stuck instances. That's the rate you pay for the cheap ammo. As a rule when a case sticks without problems tapping the butt firmly on the ground then pulling the charging handle will dislodge and eject the case. It can pay to invariably have a cleaning rod with you, if the above repair does not work, you push the case out with the rod.
Q:acrylic vs. steel tapers which is better?
Steel is better. Acrylic is porous so isn't as suitable for piercing jewellery as steel. Steel can also slide through easier for some people, acrylic isn't quite as smooth. For tapers it doesn't make a huge deal of difference as they're only passing through your ear briefly, not being worn as jewellery, but if they're close in cost anyway then go for the steel. And the plugs you insert after putting the taper through should always be steel, titanium or glass until your stretch has healed.
Q:advantages and disadvantages of steel structure?
Disadvantages Of Steel
Q:quinching steel... hardening?
boy what a though question ! let me explain. when you rapidly cool a steel from high temperatures(depending on steel type) with water or oil or other means , it is called quenching. it depends on the steel type to say if it is better to quench it with oil or water but basically in water you will have a harder steel rather than oil. for some steels if you do this you will ruin it's properties ! you can't totally tell what kind of steel do you have until you get it analyzed with Quantometer analyzer with a pocket knife it is more like an estimation and it can't be trust able generally if you can scratch the steel with your knife it means it is not a hard steel and it might not be expensive. I hope that helps but for more information i need to know more !
Q:has anyone heard about the 2010 specialized allez steel?
Steel? I doubt it's made out of steel, more labor and a heavier frame. Most likely aluminum. Shimano 2300 you say? The Shimano 2300 is the lowest of the low of Shimano road components. Most likely not too reliable and heavy. www.cyclestore.co.uk/productDetai... I think this is what you might be looking for.
Q:Welding Stainless Steel?
Yes you can use regular welding rods for stainless steel. But you will not have the properties of the stainless. The weld joint will have a different color than the stainless if you grind/grain/finish the weld. It could also rust. The joint could be weaker. It is best to use a rod that comes as close to the base metal stainless as possible. (30 years welding - certified)
Q:Welding question Can you weld copper or brass to steel?
GTAW,Weld Copper to steel, RN-60. Silver Braze Copper to Steel, Grade 4 Silver.
