Q:Steel seems to be much less expensive. What is the reason why? I've heard steel will ruin a barrel after time....is that true? But with the price difference maybe it don't matter? Is steel reliable? What are the negatives about steel I should know before buying?
steel bore - brass copper chrome-lined steel bore - steel is fine. steel jacketed bullets are harder than copper jacketed bullets and would result in higher pressure, more wear in a steel barrel than a chrome-steel barrel. chrome-lined steel is roughly 2X as hard as 4140 steel. even better, nitrated chrome steel is roughly 3-4X harder than 4140 steel. but it s fairly new is a bit pricey. most AR barrels are chrome-lined. you can tell easily if the chamber and bore has a silvery look. regular steel is just black. steel cased rounds are reliable, however plain, uncoated steel cases may feed with some difficulty due to a rougher case finish that results in more friction than the polished, smooth brass cases. cheap ammo (doesn't matter if steel or brass) always shoots more dirty. aside from that I would recommend you try a bit of each of go with whatever shoots most accurate and feeds without problem.
Q:Can steel coils be used in electrical applications?
Certainly, electrical applications can make use of steel coils. In the realm of electrical circuits, steel coils often serve as magnetic cores in transformers and inductors, which are indispensable components. The steel employed in these coils typically consists of high-quality electrical steel, possessing distinct magnetic attributes, including low core losses and high permeability. These attributes empower the steel coils to efficiently transmit electrical energy between various circuit components. Furthermore, steel coils can also find utility in other electrical applications, such as the construction of electric motors and generators. Taking everything into account, steel coils are extensively employed in electrical applications due to their magnetic properties and their capacity to handle high currents and temperatures.
Q:What are the different certifications required for steel coil manufacturers?
Some of the different certifications required for steel coil manufacturers include ISO 9001, ISO 14001, OHSAS 18001, and various industry-specific certifications such as the American Society for Testing and Materials (ASTM) certifications. These certifications ensure that the steel coil manufacturers meet quality, environmental, and occupational health and safety standards.
Q:How are steel coils used in the production of steel beams?
Steel coils are used in the production of steel beams by being unwound and fed through a series of rollers and machines. These coils are transformed into flat sheets of steel, which are then cut and shaped to create the desired dimensions and specifications of steel beams.
Q:What are the factors that affect the price of steel coils?
There are several factors that can affect the price of steel coils. These include the cost of raw materials, such as iron ore and coal, which are used in the production of steel. Fluctuations in these commodity prices can have a direct impact on the price of steel coils. Other factors include supply and demand dynamics, changes in production capacity, transportation costs, and global economic conditions. Additionally, factors like trade policies, tariffs, and currency exchange rates can also influence the price of steel coils.
Q:How are steel coils used in the automotive stamping process?
Steel coils are used in the automotive stamping process as they are unrolled and fed into stamping machines, where they are shaped and cut into various automotive parts such as body panels, chassis components, and engine parts.
Q:How are steel coils heat treated?
Steel coils are heat treated using a process called annealing. Annealing is a heat treatment technique in which the steel coils are heated to a specific temperature and then slowly cooled down. This process helps to relieve any internal stresses within the steel, improve its mechanical properties, and enhance its overall performance. The heating process involves raising the temperature of the steel coils to a critical point, typically between 800°C and 900°C, depending on the specific grade and desired outcome. The coils are then held at this temperature for a specific period of time, allowing for the transformation of the steel's microstructure. Once the desired time has elapsed, the heated steel coils are slowly cooled down in a controlled manner. This slow cooling process is vital as it allows the steel to undergo a gradual transformation, resulting in a more uniform and refined microstructure. This controlled cooling also helps to minimize the formation of internal stresses, which can potentially weaken the steel. The annealing process can be performed in different atmospheres, such as air, nitrogen, or hydrogen. The choice of atmosphere depends on the specific requirements and properties desired for the steel coils. For instance, annealing in a protective atmosphere like nitrogen or hydrogen can help prevent oxidation or decarburization of the steel surface. Overall, heat treating steel coils through annealing is a critical step in enhancing their mechanical properties, improving their formability, and achieving the desired characteristics for various industrial applications.
Q:a concrete or steel building?also, what is the density of concrete and steel? is concrete heavier in steel for the same volume?
minorchord2000 an engineer using a non-metric measuring system - it's priceless
Q:i need flint and steel. are there common household items i can get the flint and the steel from????
no common flint and steel in the house === you need to buy a Boy Scout - flint and steel fire starter kit === or a BIC lighter ... the other thing is a small jar filled with water [[ capped and water level near the top.]] hold the water-jar over some
Q:Can steel coils be custom-made to specific requirements?
Yes, steel coils can be custom-made to specific requirements.
