Q:Steel phases question!?
hey from what i learned in uni last sem, steel is originally ferrite form at first at room conditions. it will undergo poly morphic transformation to become FCC structure austenite form at 912 degree celcius. under conditions, it can become pearlite (which is a combination of ferrite and cementite) or bainitie( a finer form of pearlite). queching conditions to room temperature will form martensite which is the strongest but brittle steel form. tempered cementite is formed when we quench it and then raise temperatures before sir cooling. hope it helps, pls vote me best answer is i deserve it. thanks
Q:Pre-engineered Steel Building ........!!?
You just have to do small efforts for owing a steel building: Firstly you have to finalize a steel building company for construction work. After finalizing the steel building company, the next step is the paperwork - the agreements and contracts. Some steel building companies may also ask for a verbal approval for the factories to get the work started.
Q:what is the diiferent in composition between mild steel and cast iron?
Actually, the opposite is true. CAST IRON is generally brittle, while mild steel is not. Cast iron has a carbon content from about 2%-4%. Mild steel has less than one tenth as much carbon as cast iron- around 0.2% - 0.3%. Cast iron also typically has from 1%-3% silicon. Most mild steel contains no more than 0.3% silicon. Steel melts at ~1450 degrees C. The addition of large amounts of carbon and silicon to C.I. lower the melting point to around 1200 C and make it more fluid than molten steel. Obviously this makes it easier to melt and to pour. The main advantage of cast iron is it's cheap to produce. It also has some desirable properties despite it's brittleness. For example it's easy to cut and carve with machine tools. It's also very heat resistant and excellent at absorbing vibration. For this reason C.I. was commonly used for engine blocks and exhaust manifolds in cars and trucks in the past, (Cast aluminum engine blocks are more common these days because Al is much lighter and conducts heat better.) Cast iron also rusts much more slowly than steel which is why it's still commonly used for pipes. C.I. pipes have been known to last 300 years.
Q:TRAGUS PIERCINg?!Stainless Steel?!?
Titanium is better, and most piercings heal better with titanium used jewellery.
Q:Which is more reactive? Zinc or Steel?
Zinc. Steel is an alloy consisting mostly out of iron, In the reactivity seris, zinc is more reactive than iron. Therefore, zinc is more reactive than steel
Q:Stainless Steel Used In Knifes?
If your talking about a folding pocket knife, I think that it's basically six one way and a half dozen the other. I actually do prefer stainless for my pocket knives. I don't want to oil a knife to the degree I feel carbon requires, only to then stick it my pocket to attract dirt to the knife and oil to my pants. I'm the exact opposite on sheath knives though. I like 1095 carbon steel, plain edge sheath knives. I'll thrash on them HARD, and I rarely have major edge problems. Of course, I require them to be coated with some kind of powder coat or the like, because they can rust, but I do try and keep them clean and dry when in the sheath, so they won't pit the uncoated edge. My reasons for this sheath knife preference is multi-fold. First, these knives are simply affordable. I don't spend $80 dollars on a outdoors sheath knife. I use the tool too hard to want to spend more. I don't like the more traditional stainless steels such as AUS-8, 420HC, and 440C (not to mention the HORRENDOUS 440A) because I feel that the all else being equal, a stainless blade will bend before a carbon blade will break. I also think that carbon holds an edge at least as well, if not better, than traditional stainless, and it's much easier to hone. I don't know much about these new laminates, other than the very hard, but not so tough. They seem to be POSSIBLY too brittle for my use. That, combined with the fact that they cost a FORTUNE, means that I just won't be considering them.
Q:Measures to prevent cold rolling of packaged cold rolled steel coils? Who can give some professional opinions oh?
Cold rolled steel coils are generally sprayed antirust oil, according to user requirements, light, medium, heavy oil 3 types. Nevertheless, if the oil is volatile or in a humid environment, the steel plate comes into contact with the water for a period of time, indicating that it is beginning to rust.
Q:Is sterling silver safer than surgical steel?
Surgical steel.
Q:what is difference between high carbon steel blade for katana swords?
Carbon Steel Swords
Q:types of stainless steel?
Types of stainless steel There are over 150 grades of stainless steel, of which fifteen are most common. The AISI (American Iron and Steel Institute) defines the following grades among others: - 200 Series—austenitic iron-chromium-nickel-manganese alloys - 300 Series—austenitic iron-chromium-nickel alloys Type 301—highly ductile, for formed products. Also hardens rapidly during mechanical working. Type 303—free machining version of 304 via addition of sulfur Type 304—the most common; the classic 18/8 stainless steel Type 316—Alloy addition of molybdenum to prevent specific forms of corrosion - 400 Series—ferritic and martensitic alloys.
