Q:opinions on steel vs synthetic cable?
Steel is more dangerous, both in a fatal metal whip way and a metal splinters in my hand way. Steel weighs more. So why would anyone continue to use steel? Cost and care. Care: Steel can sit for years without having to worry about dry rot (as long as it's not out in too horrible of weather conditions). Steel is much more resistant to fraying. You don't have to baby steel so much to keep it in good conditions. Cost: As of right now, steel is less than half the cost of synthetic. A synthetic rope can cost as much as many electric winches which include a steel cable. I find that I don't use my winch nearly enough to warrent the extra care or cost of a synthetic. The weight savings would be nice, but I kind of ruined that a long time ago with the winch bumper, rock sliders, plate steel fenders/flares, belly armor and frame plating.
Q:Do they manufacture steel buckshot?
I know of no one who makes steel buckshot. Probably for several reasons. Steel is much lighter than lead. Penetration depends on energy, which is the weight of the pellet vs. the velocity of the pellet, equated into ft.lbs. Steel pellets have to travel much faster to achieve the same energy as a lead pellet. Steel, being lighter, would lose energy much faster downrange. The weight difference would be like teeing up a golf ball, and striking it with a club, and teeing up a ping pong ball and striking it with a club. The distance in flight would be obvious. Steel also, is much harder than lead, and would be hard on the barrel, and choke. It also would not deform, which would cause ricochets. Steel shot was a handicap for waterfowler's when the USFWS made non toxic shot mandatory. Waterfowl are bottom feeders, and they were eating the spent lead pellets, and dying from lead poisoning. Steel shot cut the effective range of a shotgun from 45 yards to around 35, and resulted in many cripples and lost birds. Environmetal, makes a T size shot which is .20 caliber, and is called Hevi-shot. Lead is heavier than steel, and Hevi-shot is heavier than lead. At the same velocity, you have 12 to 15% more energy than lead. and probably 20% better than steel....Hope this helps
Q:Is blue steel stronger than stainless steel? i heard it is.?
Stainless steel requires less maintenance, but I've got a K-38 Combat Masterpiece from 1974. Back then SW used the real blueing process, and the blue steel looks like its a foot deep. Probably the best looking gun in the accumulation. Still new in the box, never fired. Its my Vietnam tribute gun, same one I carried as a Security Policeman in the Air Force from 1969-1971.
Q:Where can I go to find out info about different blade steels online?
White steel is a common shorthand name for white paper steel (shirogami hagane) which can be any of several fairly simple high carbon, water hardening steel grades. The carbon content varies by grade, and runs from 0.8 to 1.4%. The range of carbon content within a grade is a tight 0.1%. For example, the carbon content of Shirogami Hagani No1A is specified to be between 1.3 and 1.4%. Each grade also contains 0.1-0.2% silicon and 0.2-0.3% manganese, and only trace amounts of the impurities sulfur and phosphorus. Blue paper steel (aogami hagane) is also offered in several grades, with carbon content ranging similarly to the white grades. However, blue steel contains the additional alloying elements chromium and tungsten, and one grade (aogami super) also contains molybdenum and vanadium. The blue steels can be quenched in water or oil, whereas most of the white grades need a faster quench and require water.

Q:Is Grade A Surgical Steel...?
Well a lot of people get microdermals done with surgical steel,yes titanium if better but it can be done with surgical steel.If you want the titanium you can always ask the piercer where they get their jewelery and if they could order them for you.You could also go to a different shop and ask if they have titanium dermals you should be able to buy them off of them.If hes an expensive piercer and your paying a lot for them you should be able to get the ones YOU want.Its YOUR body not theirs. =] hope this helped.
Q:why do you heat steel when hardening?
Gary is right, but maybe I can simplify it. It's very complex..... When you heat (hardenable) steel the carbon and iron form crystalline structures. Martensite and Austenite are most prominent, but there are others. Those are the hard crystals. When you quench it, those structures don't have time to dissolve as they would with slow cooling, so you freeze the crystalline structure in that state. Since that is too hard for most things, you temper it. Heating to a certain temp lets ~some~ of the crystals dissolve away. Annealing is heating and letting it cool slowly, so those structures will break up back into carbon and iron, leaving the steel soft. It's like a little atomic machine - crystals form, dissolve away, form again, with heat. It's waaaaay deeper than just that in detail, but that's the gist of it.
