Q:What makes Steel stronger than Iron?
Cast Iron' is typically brittle, while 'Maleable Iron' has a small percentage of carbon which allows it to be hammered and formed. Steel is an alloy that consists mostly of iron and has a carbon content between 0.2% and 2.1% by weight, depending on the grade. Carbon is the most common alloying material for iron. Steel is a crystalline structure of iron molecules interspersed with carbon molecules. This is properly known as cementite. The hardness and malleability of steel depends not only on the carbon content, but on how the carbon and iron molecules are arranged to one another. Internal stresses in the steel's crystalline structure will increase or decrease depending on the temperature it is subjected to and the rate at which molten steel is cooled. This 'tempering' can increase the strength of the steel at the expense of brittleness.
Q:About hydrolics which one used in steel melting shop?
The correct spelling is hydraulics. I haven't heard the term steel melting shop you probably means a foundry or a steel mill The most obvious example i can think of is hydraulic-operated fork lifts. Hydraulic cylinders are used to lift the forks and to tilt them upwards or downwards. The valves are coneccted to levers next to the steering wheel. Hydraulic pressure is supplied by a hydraulic pump driven by a propane or diesel engine. In some forklift designs the wheels are also not connected directly to the engine, but driven by hydraulic motors. There are also a large variety of machines used in steel mills and metalworking companies to cut and shape metal parts. for example, press brakes, plate cutting shears, stamping presses, hole punch machines, drawing presses, etc. These types all operate in much the same basic way. They use a very large cylinder or group of cylinders to apply many tons of force to different kinds of metal working tools.
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:Stainless steel or Carbon steel knives?
You didn't say WHICH type of stainless steel, which will make all the difference. There are $2 stainless steel knives and $200 stainless steel knives. The best stainless knife steels will rival the best high carbon steels when it comes to edge-holding properties. These days MOST of the best knives on the market are made from premium stainless steels because of the lower maintenance, but a high carbon steel knife has classic appeal and great edge-holding properties.

Q:Angular Velocity of a Steel Ball after a Collision?
You need to do conservation of angular momentum about the steel ball's axis. Angular momentum = I.ω The steel ball's initial ω = 5 rev/s = 5*2pi rad/s = 31.4 rad/s The steel ball's moment of inertia I = (2/5)*m*r^2 = 40*25 kg.m^2 = 1000 kg.m^2 The marble's initial ω = v / r where r is the perpendicular distance from the steel ball's axis You need to look at the diagram for this. The marble's I about the steel ball's axis is I = m*r^2 where r is the same as above. (marble is treated as a point mass). Then work out the total initial ang. momentum = final ang. momentum and solve for ω...

Q:Steel case ammo in an AK?
The ak was designed with the steel cased ammo in mind. The only real wear is going to be the chamber area, and even at that, it is going to take many thousands of rounds to wear it out. be more concerned with the corroive ammo, and clean the firearm well with warm soapy water or military bore cleaner after each shooting session.
