Q:AR-15 rounds - steel vs. brass?
steel bore - brass copper chrome-lined steel bore - steel is fine. steel jacketed bullets are harder than copper jacketed bullets and would result in higher pressure, more wear in a steel barrel than a chrome-steel barrel. chrome-lined steel is roughly 2X as hard as 4140 steel. even better, nitrated chrome steel is roughly 3-4X harder than 4140 steel. but it s fairly new is a bit pricey. most AR barrels are chrome-lined. you can tell easily if the chamber and bore has a silvery look. regular steel is just black. steel cased rounds are reliable, however plain, uncoated steel cases may feed with some difficulty due to a rougher case finish that results in more friction than the polished, smooth brass cases. cheap ammo (doesn't matter if steel or brass) always shoots more dirty. aside from that I would recommend you try a bit of each of go with whatever shoots most accurate and feeds without problem.
Q:Finding Steel for hobby welding?
They will sell any quantity of metal and even cut it to size - my experience has been that their prices are not wildly out of line for single pieces of full length stock compared to buying singles where you have to buy a minimum. They also may have sizes that ordinary places consider odd. I was looking for 5/8 square 16 gauge and was told it would have to be shipped in from Houston (to Dallas) by my nearest supplier and found it in stock at MetalSM. But check if you get something odd - the 5/8 cost more than 3/4 at both places and MetalSM actually gave me 3/4 but took it back even though I had cut it. Also check the regular steel suppliers in your area as well as retail welders metal supply places.
Q:Is Damascus Steel Fake?
Well, it depends on what you call fake. Modern Damascus steel is perhaps similar, but it is not what people would call Damascus steel in 1500. It is made to look similar, but structurally it is different. For the most part the specific way of making Damascus steel is lost to history.
Q:how is structural steel cut?
Most I-beams are manufactured in a factory by rolling the red hot steel billet through several sets of rolls till the I-beam takes it's final shape. All we normally do to a factory stock I-beam is cut it to length, trim the ends, punch out the mounting holes and or weld on shear tabs. Some I-beams like tapered ones are built from scratch in the shop using plate steel. In fabricating in the shop, a plasma cutter or cutting torch is used along with a hydraulic plate shear. Repairs during erection, usually a cutting torch because you are several stories in the air. If the beam has to be taken to the ground, still a cutting torch because on a job site power availability is poor to connect a plasma cutter. Wingman

Q:Steel structures....!!?
What information are you looking for specifically? information on steel structures could refer to lots of things. Try the American Institute of Steel Construction, or the American Society of Civil Engineers. Google to find them.
Q:can i heat treat and temper ASTM A36 steel?
A36 is plain carbon structural steel. A36 could almost be considered junk steel. It is not suitable for cutting tools in any respect, as it is far to soft to hold an edge. A36 generally cannot be heat-treated, A36 can only be strengthened by cold-working, and even then, only up to about 60,000 psi. Heating the steel will only make it softer. The only real virtue of A36 is that it's easy to work with, it's easily cut and machined and it is very easy to weld. This is good for making steel structure, but not for knives. Probably the most popular material for knife blades is type 440C stainless. 440C is easy to work with in the un-treated state, and the heat treatment procedure is relatively simple.
Q:Help with Steel and Iron please?
alloy is a mixture of multiple metals or some other elements. like some steel is mixed with carbon and iron so that alloy is more hard than the pure iron. some of them is mixed with aluminium and iron. that's all depends on the requirement.
Q:What minerals are mixed to make steel?
