Q:Carbon Steel strength grading?
Yes. Most high quality knives are made of carbon steel versus say stainless steel. High strength carbon steel holds an edge well and is strong.
Q:Spyderco or cold steel?
Given okorder.com/ but always shop around and try Ebay...
Q:Heat treatment of mild steel? Process description macro-micro
Alright, usually whu heat you heat treat mild steel, this is because you would like it stronger than you got it. To do this you must alter the grain structure of the part or in other words, the CRYSTALLITES. Ultimately you'll end up altering the nature of the grains structure changing the tensile strength it can handle, yield strength, and even change the elongation percentage that it can tolerate under load. Heat treatment controls the rate of diffusion, and the rate of cooling within the microstructure to create these elements. Usually what they use to do this is add an element to it to make it stronger such as carbon to increase its rockwell hardness, which by the way the lower you go the harder the part can become. Heat treatment can be used in more ways than this. It can also be used to weaken the parts grain structure. This will lower the parts mechanical properties making it softer and more ductile or easier to manipulate if you have to bend it into a particular shape. Typically if you allow the part to cool after heat treatment it does go through annealing. The part will be heat treated into different stages. The first being the austenitic crystal phase which depending on how hard and strong you want it, will be at its peak. When it is cooled, it will go through a will transform to martensite which is a hard yet brittle crystalline structure. Martenised part will usually be tempered to a certain degree to improve the mechanical properties to what is needed. There is more to this and you can use the link below to read more about it.
Q:High Speed Steel Information!?
wikipedia: High speed steel (often abbreviated HSS, sometimes HS) is a material usually used in the manufacture of machine tool bits and other cutters. It is often used in power saw blades and drill bits. It is superior to the older high carbon steel tools used extensively through the 1940s in that it can withstand higher temperatures without losing its temper (hardness). This property allows HSS to cut faster than high carbon steel, hence the name high speed steel. At room temperature, in their generally recommended heat treatment, HSS grades generally display high hardness (above HRC60) and a high abrasion resistance (generally linked to tungsten content often used in HSS) compared to common carbon and tool steels. see reference for more info .
Q:Help! About Steel!?
The strength and corrosion resistance depends on the mix. Pure steel is pure iron plus 6% pure carbon. It is the carbon molecules that give it a tough crystallized strength. Pure iron is wrought iron and you can bend that with your hands. Strength also depends on the shape of the beam the most common steel beam is the W flange more commonly called the I beam. That is because the strength of the ‘I’ beam is just a little bit less than if the entire I beam was filled in; however the weight and material savings is huge. Steel itself has no corrosion resistance and is often given a zinc coating just to resist oxidization. Manganese, vanadium and tungsten are just some of the other elements added to improve the steel.
Q:What is the accuracy of steel tape inspection
This is the smallest scale brothers precision measuring tools, minimum scale steel tape is mm, mm is estimated to read out the data, such as steel tape measure length is 12.5 mm, which is 12 in the steel tape on the scale with the number of 0.5.It was read out. So the accuracy is millimeters.
Q:how to wash/clean stainless steel fridge?
Quite a few companies make stainless steel cleaners. Don't use Windex, I was told when we bought our stainless fridge and stove. Go to Home Depot or a store like it and I am sure they will have some to choose from. I bought these pre-treated wipes for Stainless Steel at Bath Beyond (like Lysol makes) and they work wonders for a quick cleaning. Linens N Things also has some wipes.
Q:how do I build a steel galvanizing plant. Hot dipped Galvanization?
bcaz of the very corrosive conditions in petrochemical plants, steel without coating doesnt work. coating with zinc (e. g. hot dip galvanizing) help protecting the steel for more time, in simple words , zinc is corroded instead of iron and until there is some zinc on the surface steel is protected. we usualy dont use paint coating bcaz: 1.any porosity in the paint coat result in severe corrosion and steel should be completely coated with paint to be protected ,instead large prosity in zinc coating doesnt matter at all 2. usual painting materials arent proper for the severe corrosive condition ASTM standard( american society for testing and materials) offer world accepted standards for painting quality control
Q:Do any of you teens out there know what a Steel Guitar is?
Well, my digital piano has a Steel Guitar setting that makes it kind of sound like one, but other than that I know nothing about them.
Q:How difficult is it to harden steel?
harder steel has a higher carbon and chromium content
