Q:Judge Quality of Steel?
The quality of the alloy can be very well be judged by its appearance and lustrous surface. The more luster on the surface the more refine will the steel be. To judge its tenacity and endurance, the alloy can be subjected to a series of procedures involving stress and shock. The reaction to these processes can determine whether the steel be fit for the purpose required.
Q:What is the maximum width of galvanized steel strip, please? The galvanized coat is 275, and how long is one coil?
As far as I know, the galvanized rolls of WISCO are wider in width than other domestic steel mills, and can produce 2080 wide steel coils.
Q:Key differences between the term structural steel fabrication & steel fabrication?
Structural steel is steel construction material, a profile, formed with a specific shape or cross section and certain standards of chemical composition and strength. Structural steel shape, size, composition, strength, storage, etc, is regulated in most industrialized countries. Fabrication, when used as an industrial term, applies to the building of machines, structures and other equipment, by cutting, shaping and assembling components made from raw materials. Small businesses that specialize in metal are called fab shops. Steel fabrication shops and machine shops have overlapping capabilities, but fabrication shops generally concentrate on the metal preparation, welding and assembly aspect while the machine shop is more concerned with the machining of parts.
Q:difference between titanium and stainless steel?
Stainless steel is more corrosion resistant than steel and titanium is more corrosion resitant and lighter. However, titanium is more prone to picking up (scratches caused by normal tools creating scratches and leading to stress fractures). The Lockheed Blackbird had to have tools treated lithium grease (i could be wrong) to prevent this. I'd stick with stainless steel as i think any titanium exhaust you can buy will be a titanium composite due to its cost
Q:Explain how you could make plastic sink and steel float?
you can use the steel to make a hollow box, or a ship. There are thousands of steel ships floating in the oceans. plastic, specific gravity ranges from 0.6 to 2, so the higher density ones will sink. Here are some that will sink: Nylon (Polyamide) 1.15 g/mL Plexiglass (Polymethylmethacrylate or PMMA) 1.19 g/mL Lexan (Polycarbonate) 1.2 g/mL PVC (Polyvinyl chloride) 1.16-1.38 g/mL PETE (Polyethylene terephthalate) 1.38-1.39 g/mL .
Q:What could the impurities in steel wool be?
Impurities in steel wool would be of the elemental type. I'm sure steel wool is a mixture of different low grade not good for much of anything else materials. There may be excessive impurities such as lead, cobalt, boron, aluminum etc... in the steel wool. There may also be solvent residue on the wool i.e cleaner, lubricant etc.. I'm sure every batch is different - I know the iron level is high thats what makes them rust quickly.
Q:Best steel for a all purpose knife?
Do you want apples or oranges? It's that kind of question. Here's my opinion. For large blades (over 6) 5160 or L-6 done properly makes a nearly unbreakable knife. I once pulled my 65lb vice out of the work bench with an 8 L-6 blade. As carbon content goes up edge holding increases but at the cost of overall strength. For smaller blades I prefer O-1 and 52100, these steels have about twice the edge holding as 5160 but cannot pass the 90deg bend test without breaking. 1095 is a fine steel, I prefer to make damascus from it, but when I do make a blade I want to show a temper line as this steel will do it well. Then we get into high alloy, D-2 is about as balanced as they come and for a smaller blade is second to none save the CPM steels. The CPM steels are very expensive and like the homogonous steel come in many alloys. As far as a chipping edge, that's more an indication of improper heat treating than anything. Carbon steel has more strength and edge holding potential than stainless. D-2 has enough chromium to be somewhat stainless but not beyond the threshold that grain growth becomes an issue. One last thing, the grind is important. The popular hollow grind cuts easily but is weak at the edge because it is thin. A flat grind has more mass and done properly cuts as well as the hollow. The convex is the strongest and is best suited for chopping or a polished edge to push through the material.
Q:Thermal expansion of steel?
It seems you are trying to convert celsius to Fahrenheit, Why? There is no need. Delta L= alpha (initial length) (delta celcius) what you need is an alpha, it should be given in degrees celsius to the negative first (steel's alpha happens to be 0.000036 1/celsius). You also need the length of the beam at 35 degrees C. This answer (delta L) needs to be added (if heat is rising) or subtracted (if heat is dropping) to the original length.
Q:what is the tensile strength of steel?
It is refereed to the ultimate tensile strength which is the point at which the specimen of steel fail (rapture) when subjected to a force,measured by unit force divided by cross section of steel.
Q:Where can I find an atomic structure of carbon steel?
This Site Might Help You. RE: Where can I find an atomic structure of carbon steel? What website can I use to find a good picture that shows the atomic structure of a carbon steel?
