Q:Why low carbon steel have poor magnetic properties?
The composition of the steel is almost tertiary to many other considerations, except that there are certain elements and percentages of elements which tend to affect the crystaline structure in the steel. The most basic question is whether the crystaline arrangement of atoms in the steel is martensitic or austenitic, and many factors influence that. In general, martensitic structure is magnetic and austenitic structure doesn't respond much to magnetic fields, but there are varying degrees of martensitic and austenitic -- there is never a pure state. Read the articles at bottom.
Q:Engineering Materials - tool steel question?
It all depends what the application actually is. For hammers I would select a hammer grade B1 steel. For impact loading where an edge is needed I would be going for O1 or similar (oil quenching steels tend to be a little tougher than air hardening). For mining tools a very high manganese steel (Hadfields steel) - this is not a true tool steel. The best place to start is by looking at the ranking of the properties which you want - hardness v toughness v strength - and then use this to put the steels in rank order. Price and availablity then sort the problem out for you (in the real world).
Q:how to make a unique piece of steel?
If you really want to do this, you should be getting some books on steel metallurgy rather than asking on Yahoo. ASM sells a Metallurgy for the non-metallurgist that would be a good introduction. Most university libraries will have the full ASM handbook that includes detailed information for different grades of steel (vol 1), heat treatment and surface hardening (vol 4), testing (vols 8-12), and casting (vol 15). A reference for continuous cooling transformation diagrams will also help in designing a heat treatment process. If you want to make something stronger than most commercial steels, you'll need to get into nanotechnology and unconventional steel processing methods like powder metallurgy. You can increase the strength of steel by about 1000% by reducing the grain size from 50 micron (typical for conventional processing methods) to 100 nm (achievable through high-energy ball milling). Though you'd also need to customize the chemistry to stabilize the grain size during the necessary thermal processing, I believe zirconium works well with iron.
Q:I buy steel!!!?
Not sure what the question is. Oh...and this isn't a place for classified ads.
Q:AK47 firing through steel?
It can't go through inches. It can go through up to 1/4 of an inch of plate steel but not much more. An M-16 can go through it as well and has less powder behind it but the 7.62X39 is a fat round and it takes a little more to get it through.
Q:who would buy shredded scrap steel in GTA?
We are one of the biggest steel mills in Asia. Under our group, we have steel mills in Thailand and Bangladesh. On the monthly basis, we purchase steel scrap HMS1/2 80:20 and the shredded ISRI210/211, ISRI211 by bulk and 20' container to Thailand and Bangladesh. Due to the limitation of our existing shredded steel scrap supplier, we need to get more supply of the shredded. Please contact us or offer us of ISRI 210/211 or ISRI211 CFR Chittagong, Bangladesh with 500mt - 2000mt per shipment by 20' container. If any questions, please feel free to contact us.
Q:Which is a greener building material, steel or wood?
Of course wood+1
Q:my first pedal steel guitar?
Try okorder.com -The Art of Steel Guitar/ Steel guitar players -Take it away Leon- McAuliffe and 'Speedy West' were a couple greats. In the late '50s, Speedy was playing a Fender 1000 Pedal steel. He often did duets with Jimmy Bryant The Fastest Guitar Player In The Country! / note also the 'Emmons Guitar Company':
Q:Whats better, 1045, or 440 stainless steel?
Type 440 combines such a high grade of cutlery steel, toughness and economy that it is actually known as razor blade steel. Browsing around (a lot) more, it seems that 1045 Surgical Steel is popular in straight razors used by barbers. These razors are honed by stropping with leather and last practically forever. From the above, I would guess that it might be easier to lose the edge on 1045, but also easier to re-sharpen it, that it won't easily knick because probably not so hard as 440. I'm not sure if it would be more expensive, unless it has a superior handle etc. So, I would expect to spend a little more effort over the lifetime of the 1045, maybe pay a little more for it, but have a longer lifetime. hth.
Q:How do I remove rust from a steel saw?
I would suggest rust removal by electrolysis. Search youtube for that. It probably will not affect the metal but there are no guarantees. I would run a test on another metal. Also this process can be dangerous because hydrogen gas is a by-product - remember not to smoke or be cooking nearby! The Easy way is with BlackStar Rust Remover. It will turn the metal black and convert the rust to metal which can then be painted or left black.
