- Q:Does Stainless Steel rust?
- Theoretically stainless steel is supposed to be what it's name says it is - stainless. However there are different grades of stainless so yours might dis-colour if it's low grade. Think of all the stainless steel cutlery you use to eat with - if you keep it clean it doesn't go rusty ; it can if you don't look after it.
- Q:Heat treatment of mild steel? Process description macro-micro
- Mild steel is a solution of carbon within iron, etc. When the steel is very hot the carbon is well distributed. As the steel is cooled iron crystals form excluding the carbon that will then collect at the boundaries (grain boundaries) between iron crystals. If cooling is rapid at any point in the cool down crystal growth will cease (affecting final grain size and the mix of carbon and iron at the grain boundaries). The ductility or hardness of the resulting steel will be determined by the grain sizes and makeup of the carbon/iron mix between grains. Ductile iron permits 'slabs' of iron to slip past each other within iron crystals and location of carbon atoms may help prevent slip resulting in hardness. Therefore, heat treatment usually consists of 'soaking' the steel at a temperature high enough to dissolve all the carbon uniformly then cooling it down slowly or rapidly to obtain optimum grain size and interstitial carbon between grains to obtain desired 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:what effect does reducing the carbon content have on the properties of steel?
- Very high carbon steel (0.96 to 2.11%) is hard and not very ductile (difficult to mold or shape). It is also difficult to weld, but has the lowest melting point. As the carbon content is reduced, the steel becomes softer, more ductile and melts at a higher temperature. Stainless steel is an alloy of Iron, Carbon, Chromium. The fourth element would depend upon the grade of steel, but Nickel is probably the most common.
- Q:Why are most homes framed of wood rather than steel?
- In most locations a 2x4 is slightly cheaper than a steel stud. The labor is cheaper with wood because it's less skilled and there are many people to swing a hammer cheaply. Most contractors do what they know and most only know wood.
- Q:where is cold formed steel framing used?
- It will vary from location to location. A possible way of telling is how the material is joined. If the material is riveted together it is likely cold rolled. If the material is welded then its probably normalized steel (possibly annealed but less likely). Cold rolling increases the yield strength of the material so less of it is needed. However, it also make the material more brittle. Welding creates defects in the region surrounding the weld and these are more likely to grow and cause failure in a cold rolled steel than a normalised or annealed steels. In addition the heat from the welding will change the microstructure that was deliberately introduced by the cold rolling process resulting in a localised drop in yield strength. Normalised and annealed steels are more ductile and tougher than Cold rolled steel but they have a lower yield strength. Because they are tough and ductile they are less sensitive to crakcs and defects so welding won't lead to as big a reduction in strength. Another possible consideration is the environment they are used in. Steels exhibit a transition temperature (actually more like a range) where they go from behaving like a ductile material to a brittle material. A well known example of what this can cause are the Liberty ships in WW2 (Supply vessels from the US to the UK). These were made by welding together sheets of cold rolled steel to form one continuous Hull. Unfortuantely the transiton temperature of the steel taht was sued was around 4 degrees while the Baltic Ocean is about 0 degrees. As a result small cracks would grow and then when the reached a critical size they would tear through the ship at the speed of sound in the metal (1500m/s) and these massive cargo ships would literally snap like twigs. So, if the steel is being used somewhere really cold its unlikely to be Cold rolled too.
- Q:Steel vs. Dark Pokemon?
- i would choose dark because it has alot more speed and power steel focuses more on defense a good team would be something like Umbreon Honchcrow Shiftry Spiritomb mightyena Sharpedo
- Q:Steel Price .........!!?
- depends what u want..
- Q:STAINLESS Steel....?
- Stainless Steel is named that because when compared to untreated steel it is virtually stainless. It is virtually stainless, and harbors very little germs and bacteria. That is why it has been the standard in the food industry for years.
- Q:Is boron steel harder?
- Boron Steel
