Q:Besides stainless steel....?
can she wear sterling silver or white cooper?
Q:serious question! Dual-phase steel?
Dual Phase steels refers to a distinct group of alloys which are used for automotive bodies. These were developed to give improved deep drawing (for shaping) and strength while on the road. Most of the work was started at the same time in the 1970s as a response to the oil crisis (history repeats!) with SSAB in Europe, US Steel and British Steel leading the way. There are many variants of the dual phase alloys prefered by each of the auto manufacturers. The work on these steels led the way for TRIP (transformation induced plasticity) steels, rephosphorised steels and HSLA (high strength low alloy) steels. There is a distinction between these steels and duplex steels which typically refer to austenitic/ferrtic stainless steels. Also be aware that everyday low carbon steels with 0.1%-0.6% carbon will have a ferritic/pearlitic structure but are not considered to be dual phase So to summarise: Who - major steel companies worldwide When - from about 1973 onwards (up to around 1977 when the developments went in other directions) Where - Europe, USA and Japan (but I'm not sure who it was in Japan doing the work)
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:What company sells strong steel doors for homes?
You can find strong steel door here...
Q:I buy steel!!!?
..mm where are you located? .. how much steel is a lot of steel to you? .. whats it worth to you? .. do ya want it from salvage sorce, or from milled sorces? There is a lot of it around, even places that would pay ya to haul it off..
Q:The difference between aluminized color steel roll and ordinary color steel roll
Aluminized color coated sheet is a new type of material produced in China in recent years due to its high end applications. It is often used as an indication of CCLI. It is made of galvanized steel sheet (55% aluminum, 43% zinc and 1.6% silicon), which is more galvanized and more corrosion resistant. It is processed by surface degreasing, phosphating and complexing treatment, and is coated with organic coating.
Q:Which one is better to start? Steel or Acrylic tapers?
steel because they dont get that infected also they sre easier to put in. but they do get cold in the winter
Q:What exactly is broken steel in fallout 3 and does the game end if you have broken steel?
Broken Steel is a dlc for fallout 3 it ups the level cap and makes it have more quests after the game is over
Q:how to clean old steel coins?
if you collect coins, you need to learn that they must never be cleaned. cleaning, while it might make them look pretty, ruins their value as a collectable. ask your coin dealer.
Q:what is the stucture of high carbon steel?
That is kind of a broad question because high carbon steel can cover a broad range and you did not mention the condition. But I will try to keep it simple. If it is in a wrought condition, it would likely be pearlite plus carbides along the grain boundaries., The atomic structure would be body centered cubic. Sometimes high carbon steel is spherodized annealed and that would be ferrite with lots of round carbides. The atomic structure would be body centered cubic. If it is quench and tempered, it would be martensite and would probably have noticeable carbides if the carbon content was high enough. The atomic structure would be body centered tetragonal
