Q:What steel is the most magnetic?
From what I understand, the best material for cores is not the most magnetic but the rather the one having less loss due to hysteresis,
Q:what happen if carbon steel is exposed to an oxygen?
Assuming the steel isn't actually melted, two things will happen. First, a layer of iron(ii) oxide, FeO will slowly develop on the surface, getting thicker over time. This layer is usually poorly bonded to the metal surface, it tends to flake off, exposing fresh metal. This is known as mill scale, it's also known as wustite which is the mineral term. Second, the surface of the steel will become decarburized, essentially becoming pure iron, not steel. The depth of the decarburized layer depends on the temperature, time, and the diffusivity of carbon in the steel at the given temp. This has some implications to engineering, in hot-rolling or forging of steel shapes for example. It's often the case that the stress and strain in a material is greatest at or near the surface. Therefore the weakened, decarburized layer at the surface may have a much greater detrimental effect on the steel's performance than might be expected. In a more specific example, die and tool steels depend on their carbon content for their strength and wear resistance, Therefore if such steels are heated in an oxidzing atmosphere, wear resistance is totally destroyed: The thin decarburized iron layer will be extremely soft and malleable.
Q:I want to make a stainless steel chess set and need help...?
stainless steel is really hard to work with and will be really expensive to pour as not too many foundries do that. As far as tools go, I know that for e.g.drilling stainless steel cobalt bits are best, but even they don't last for very long. If you use normal drill bits stainless steel will ruin them. So how much metal working skills do you have? I would suggest to use a material you have experience with. Or make a chess set from nuts and bolts. You can buy them from stainless steel and the assembly is easy. See links for a few examples and/or use google to find more.

Q:What are black steel pipes made of ?
Black Steel or ductile steel pipes are made from scrap for the most part. Galvanized pipes are made from new raw materials and are electroplated to resist rust.
Q:how do you rate the hardness of steel?
There's an instrument called a hardness tester. It has a stylus which is pressed into the surface of a sample of steel with a calibrated amount of force. The distance it penetrates tells you how hard the steel is. (This is sometimes called 'indentation hardness'). The most common scale is the Rockwell Scale. Actually it gets a little complicated because there are several scales, one for tungsten carbide (the hardest man-made material), one for aluminum and brass and soft steels, and one for hardened steels. Another scale for indentation hardness is the Brinell scale. It's a little less complicated, with one scale to measure the hardness of wood, plastic, etc. as well as steel.
Q:Steel horse shoes vs. aluminum?
IMO, steel is fine. The only time I've felt that aluminum was important was: 1. A horse with a specific shoeing issue that required an aluminum shoe. 2. A racehorse-- every micro-gram counts. 3. Top level pleasure horses who need a little bit flatter knee. Everything else I've seen did just fine in regular steel shoes.
Q:Can carbon steel be solution annealed?
No. Carbon steel has two different crystal structures, FCC and BCC , depending on the temperature. when you heat steel up and then quench it, it locks the crystal structure into the BCC form. this makes it hard. whereas precipitation hardened austentic stainlesses remain BCC regardless of the temp, so the hardness change is not a function of thermally induced strain. you can anneal carbon steel but the thermal profile is closer to the precipitation profile of PH stainlesses than it is to the Solution annealing profile.
Q:Best hunting knife steel?
Don't know much about steels, but apparently SV30 is the toughest son of ore you can look for, and it's so tough I've heard of knife makers rejecting it for softer steel. Look for Gerber and Buck for low end SV30 knives under $100.
Q:Would aftermarket steel wheels weigh more than stock jeep wheels?
steel is steel is steel- they will always be heavy you would have to weigh them to find out--NOW if you are going to alloy wheels they are typically aluminum and yes they are lighter -this is good because it lightens your un-sprung weight and is less harmful to your suspension-good for your auto
