Q:how is structural steel cut?
Most I-beams are manufactured in a factory by rolling the red hot steel billet through several sets of rolls till the I-beam takes it's final shape. All we normally do to a factory stock I-beam is cut it to length, trim the ends, punch out the mounting holes and or weld on shear tabs. Some I-beams like tapered ones are built from scratch in the shop using plate steel. In fabricating in the shop, a plasma cutter or cutting torch is used along with a hydraulic plate shear. Repairs during erection, usually a cutting torch because you are several stories in the air. If the beam has to be taken to the ground, still a cutting torch because on a job site power availability is poor to connect a plasma cutter. Wingman
Q:How can i make difference between iron and steel?
Iron and steel have different thermal expansions and specific heats. You could either heat it up and see how much it changes in length or you could put it in water inside a calorimeter and observe how much the temperature of the water changes
Q:Is stainless steel good for a butterfly knife?
This isn't really a question for this section, but I'm still happy to help out since I'm a big cutlery nerd as well. One thing to look out for when buying a knife is a lack of specifics on what steel is being used. High Carbon Stainless Steel doesn't tell you what the steel is, just what it MIGHT be. Chances are it's something along the lines of 420HC or 440A, both of which are softer steels. They aren't the worst steels around, but they are very quick to dull. You'd be better off looking at the Balisongs of Benchmade. They'll cost more, but you'll know that you're getting something made with quality materials and that won't break on you. And if it does break for some odd reason, Benchmade's warranty and customer service are both fantastic. Although if a more questionable knife is okay with you as long as the price isn't too high, then at least 420HC and 440A aren't too brittle and will take a decent edge even though they'll dull quickly. As for whether stainless steel is good for a knife or not, that depends on the type of stainless steel and what you're going to use the knife for. Many stainless steels are more brittle than a carbon steel, so high carbon stainless steels are a bit more likely to rust but a little tougher as well. In a butterfly knife, a steel like that is a good way to go, although the steels used by Benchmade, as I mentioned, are of a much better quality.
Q:What is the malleable temperature of carbon steel?
It needs to be RED hot, the hotter the better. Yes you can use a camp fire if you put the file directly in the hottest part of the coals, but it'll take about 5-10 minutes to heat. Charcoal briquettes would probably work better as a heat source. You can use something like a blow dryer to intensify the coals, that might help. You'll also need a bench vice, and the biggest pair of pliers you can find, for leverage. Bending steel's not easy even when it's hot. You could also use a bit of steel pipe that'll fit over the end of the file. Stick the file in the vise when red-hot, slip the pipe over the free end, and use the pipe to bend it. OR, you could use the old-fashioned method of just holding it with pliers in one hand, and hitting it with a 5lb sledge hammer with the other. use something solid as an anvil, like a large steel pipe. you mighe be able to get away with using a small log, but you'll have to work twice as hard. Safety glasses are MANDITORY for this type of thing. Do not attempt without eye protection at all times. Ear plugs are also a very good idea.
Q:Remington 870 wingmaster steel shot duck hunting?
Because of environmental concerns steel, bismuth and tungsten is replacing lead shot, for bird hunting. The problem with steel shot is the hardness, which can cause damage to the bore and choke in older shotguns. Unlike lead there is no give to steel and it can damage the bore especially if the choke is on full. Tungsten is also very hard, but it is often alloyed with other metals making it softer causing less damage in older models shotguns. Bismuth falls in between tungsten and steel, being the softer of the two by far.
Q:Steel shot?
All buckshot I can think of at the moment is lead. Steel shot is used for waterfowl hunting because lead is illegal for that use. They don't want all that lead shot falling back in the water and causing lead contamination. There would be no reason to make steel buckshot, and it would be pretty ineffective. Steel is much less dense than lead. So a steel 00 pellet would weigh much less than a lead 00 pellet. So it would carry a lot less energy to a target. Buckshot is used for just that, Bucks. Well large game like deer, bear, and for self defense. In uses like that you need that extra energy. Lead shot is used for everything, except where lead shot is illegal, which is waterfowl hunting. Steel shot really isn't very popular anymore. Waterfowl shot just can't be lead. It doesn't have to be steel. They've come out with other stuff, like bismuth, that is a lot more dense than steel, but still not as dense as lead.
Q:Brass or steel cases through an AR-15?
What the person that told you that failed to mention is that steel ammunition is slightly less malleable than brass so it does not expand as tight to the chamber walls to seal the gap from expanding gasses. This causes a little bit of carbon to build up over time and can make brass ammunition get stuck. The simple solution is to shoot brass before steel, or to clean the chamber really good after firing steel ammunition.
Q:How to restore rusted stainless steel?
Nope, stainless steel is actually coated steel that can be removed by acid or scrubbing too much. it would need to be re dipped to go back to normal. would cost a fortune however.
Q:Steel plugs in the winter?
Personally, okorder.com They are spot on for sizing, they do customs, and amazing quality like i have never seen before and I have been through a lot of plugs. Hope this helps :)
Q:what steel is best for a sword?
Carbon Steel is the most common, while most live-steel(designed for use) ready sword utilize on of the spring steels you mentioned. Hybrid steel like those used in the Slayer series seem neigh-indestructible. The steel should be strong enough to not notch on a strike, but flexible enough to flex when you bend it, lest it shatter on a hard blow.
