- Q:Is boron steel or carbon steel a harder metal? Which one is more flexible?
- The only thing that affects the hardness of steel is the carbon content. But there are many elements that can make it easier for a steel to achieve its maximum hardness. And Boron is an extremely effective element that increases the hardenability of steel. Adding as little as 0.002% Boron can have a big impact upon quenching of a steel. Boron is usually added when you need the hardness of a heat treated steel part to extend deep below the surface. For example, lets say you had a two identical plain carbon steel parts, but one had boron and the other didnt, and you wanted to heat treat them both After quenching, the surface should be the same on both, and lets say its 55 Rockwell C. In the plain carbon one, the hardness might drop down to 50 at 2mm under the surface, but the boron treated one might not drop to 50 until 4mm under the surface. Now, these numbers were completely made up, and it would depend on the specifics as to what the difference might be.
- Q:it isn't a SIGG water bottle or any other brand, as it's from thingsengraved what I'm wondering is, is this just as good as a SIGG water bottle, or is there any difference?
- The problem with stainless steel water bottles is the steel takes even longer to decompose in our landfills then plastic its self. So it just adds to the waste. If you use steel be sure to recycle it when you are done using it. Another problem is the fact that we don't really make steel here anymore so you have to pollute the environment shipping steel here that the bottles are made from. It gets ship here on trucks, ships, and what not. Very big polluters!! You'd be better off just getting a reuseable bpa free plastic water bottle made in the usa. Or some of those expensive corn cups.
- Q:Could someone please explain what happens when steel is heat treated and why these happenings cause the steel to become harder? Please dig down into the micro details of the crystallites but in somewhat laymen's terms. Also describe the processes which achieve these results; if you have the time. Thanks for your time and effort.
- 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:like the steel industry and the effects it had on industrial growth, 10 points!
- The single most important important advance in steel production was learning to accurately control carbon content. This was done through the Bessemer Process in which air was blown through molten iron to burn out impurities and excess carbon. Low carbon iron (wrought iron) could be easily worked into shapes. Medium carbon iron could be cast into useful and durable shapes. High carbon steel could be used for structural uses (beams and girders). Adding alloys such as nickel and silicon could produce very tough steels and steels resistant to rust. Adding vanadium to steel engine parts allowed Ford to produce finely machined engines in huge numbers with existing machinery.
- Q:How are steel coils used in the manufacturing of industrial pumps?
- Steel coils are used in the manufacturing of industrial pumps as a primary material for constructing the pump casing, impellers, and other critical components. The steel coils are first uncoiled and then cut into specific shapes and sizes, which are then formed, welded, and machined to create the various parts of the pump. The strength, durability, and corrosion resistance of steel make it an ideal choice for ensuring the longevity and reliability of industrial pumps in demanding applications.
- Q:How do steel coils contribute to the HVAC ductwork industry?
- Steel coils are an essential component in the HVAC ductwork industry as they are used to fabricate and shape the ducts. The coils are formed into various sizes and shapes, allowing for efficient air circulation and distribution within heating, ventilation, and air conditioning systems. These durable coils provide structural integrity to the ductwork, ensuring a reliable and long-lasting solution for HVAC installations.
- Q:How are steel coils used in the production of steel rings?
- Steel coils are used in the production of steel rings as the primary raw material. The coils are unrolled and cut into smaller sections, which are then shaped and welded together to form the circular shape of the steel rings.
- Q:What are the different types of steel coil slitting methods?
- There are three main types of steel coil slitting methods: rotary slitting, loop slitting, and pull-through slitting. Rotary slitting involves using circular knives to cut the coil into narrower strips. Loop slitting involves passing the coil through a loop that is formed between two sets of knives, which then cuts the coil into multiple strips. Pull-through slitting involves pulling the coil through an adjustable slitting head, where the knives cut the coil into desired widths.
- Q:I want to know if it is possible to make regular steel stainless.From what I understand stainless consist of chromium about 10 percent I think.Any way I'm wondering if properties can be added in a process or can this only be possible during actual manufacturing of the steel.And I'm not talking about chrome like stainless steel that's not to shiny.
- no an alloy essentiallly does not exibit its constituent properties if you want to add anymore the thing should be molten and hot and homogenous homogenous being the key word and no ss essentiallly mean that thing only
- Q:Why is it usually scorned by the shooting community to use steel cased ammo (like Wolf)? Always hear corrosive and steel is bad for the extractor/firing pin. Hulp a simpleton out!
