Q:Are steel casings reloadable?
Let me break it down for you. 1) There are two kinds of priming in current use these days -- you cannot tell from the outside which primer it is...only by looking inside the casing. If the casing has a single center primer hole, it is Boxer primed. If the casing has multiple primer holes, none of which is center, it is Berdan primed. Berdan and Boxer are the names of men who designed the priming systems.
Q:Why low carbon steel have poor magnetic properties?
The composition you mention is not a low carbon steel.The carbon and manganese content are high enough to mean that the crystal grain size will be small. A very large grain size is needed in steels for transformers,motors etc.The large grain size and lack of carbides in low silicon steels for magnetic purposes allows the easy movement of magnetic domain walls.Transformer steels typically have a carbon content of about 0.003% and 3.5%Si with the phosphorus and sulphur at a tenth of the levels you mention.The high Si content increases the electrical resistivity of the magnetic core and reduces the power loss from eddy currents(the core metal has voltages generated in it by the changing magnetic fields) and the power lost in eddy currents heats up a transformers core so it needs extra cooling;the loss is inversely proportional to the resistivity and 3.5%Si increases resistivity of iron by a very large amount.The presence of high silicon with ultra low carbon and manganese level allows the soft magnetic steels to be annealed at very high temperatures(850 to 1100deg C)without a phase change so that the crystals have 10,000 to 10,000,000 times the volume of the crystals in heat-treatable (Just)steel you mention.Fine for playing with and demonstrating electromagnetism but not as electrical engineering feedstuff.
Q:Stainless Steel Used In Knifes?
There okorder.com/ Stainless steel doesn't make the best knife blade. It doesn't sharpen as sharp or hold its edge as well. High carbon steel is better, but it rusts and discolors very easily so it's not as popular. A new thing (actually not new but popular these days) is to use a 'sandwich' of high carbon steel between two layers of stainless. So the actual edge is high carbon steel but the blade looks like stainless. I have some kitchen knives made this way (kind of expensive) and I love them. This same technique was used in Japanese katanas, swords used by samurai warriors.
Q:Iron heavier than steel?
Steel is iron, with other things added that strengthen it and/or make it less rust liable. So, in general, steel is stronger than iron. In so far as the density, that depends on the steel alloy. Some are higher than iron, some lower. Remember there are hundreds of different steel alloys. edit: but the density is still close to that of iron. density steel 7750 to 8050 kg/m³ density iron 7870 kg/m³
Q:The difference between aluminized color steel roll and ordinary color steel roll
Substrate selection: AZ150 (aluminum zinc content 150g/m2); G345A high strength galvanized steel sheet (55% aluminum, 43% zinc and 1.6% silicon) corrosion resistance data: 5%NaCL 35 DEG C, 1000Hrs, Field good, Scribe, No, Blister, 2mm belowQ.U.V: 2000hrs, MAX.2 color, light to keep the rate above 90%, the above data show that aluminum zinc coated board (AZ150, G345A, PVDF) is very suitable for the extreme environment of buildings or other facilities, highly corrosion resistance and weather resistance, and the major steel plate can ensure the service life of 20 years. In addition, high strength steel has been widely used abroad, and it has good economic performance, and it is also the domestic development trend.
Q:Steel Building Structures?
Which steel buildings are you asking about? The Empire States Building has a steel frame and is completely weatherproof. Most industrial factories have steel frames and are weatherproof. It is the cladding that makes them weatherproof. By the way there is a difference between weatherproof and waterproof.
Q:steel building for horse barn?
a great style of human beings are putting up those steel homes made by making use of agencies like Cleary or Morton because of the fact they are greater fee effective. yet in my opinion, i don't think of they greater wholesome horses all right. They dent very relatively, all the horse has to do is lean against it somewhat. additionally they provide no insulation so as that they are like little ovens interior the summertime and are fairly chilly interior the wintry climate. in case you're able to have adequate money it, i might flow with a competent previous formed timber barn.
Q:Is mild steel environmentally friendly?
Steel just rusts, it doesn't produce any emissions just sitting there. They even make architectural steel called Corten to rust to a nice patina. If you consider how the steel was made in the first place, a great big NO! Steel making requires massive amounts of electricity plus it gives off some nasty fumes in the liquid state. Leather itself doesn't emit much of anything, but the dyes might. Again though, if you look at how it's made, tanning leather is right up there with steel mills and paper mills for pollution, some of the worst.
Q:Steel Building Construction.............?
A true structural steel building is composed of steel columns, steel bar joist,steel purlins,steel roof frames,and steel siding. This is all load bearing structural steel. The vulnerable area of a steel building is the exposure of this steel to extreme temps during a fire. Steel becomes weak at high temps and begins to twist and distort like a noodle in hot water. Most all steel buildings now are specified by the architect/engineer to have fire retardant spray applied to the key components to protect against high heat during a fire. Even with that some beams/columns are also wrapped with several layers of type x fire rated drywall. Multi story steel buildings usually have lightweight concrete poured over steel decking for all floors above the ground floor. Any and all penetrations in these concrete floors must be sealed around to stop fire and smoke from spreading from one floor to the next, and fire rated doors at all stairways to each floor. Even ductwork that runs to other floors must have fire rated dampers that close if signaled by a sensor, this stops smoke/fire from spreading through the ductwork. Sprinkler systems are usually required in new structures that exceed at pre-determined square footage by the state you are in. Hope this helps you out.
Q:Steel or wood?? About the resistivity?
Steel is a conductor while wood is an insulator. There are no free electrons available in wood for conduction of electricity to take place. So wood has more electrical resistivity than that of steel.
