Q:Does the factory choke on my rem. 870 handle steel shot?
All Modified chokes will shoot steel with no problems. It is only when you get more restrictive, full, xfull, and on that you start to run into problems while shooting steel. There are manufacturers out there that make full chokes that can use steel. Carolson is one of them. That is if you want a full choke for steel.
Q:making holes is iron and steel?
It really depends. If you are drilling iron, I assume you are talking about cast irons and there are many different types, some are easier to drill (and machine) than others. For steels, there are many many different types of steels which can have a huge range of physical properties. In fact, your drill bits are almost certainly made of some type of steel alloy. If your drill bit has the same hardness as the steel you are trying to drill, it will be difficult to drill. If the steel is harder than the drill bit, you won't make a hole, you'll just break your drill bit into smaller pieces. There are drill bits that use carbide inserts or diamond composite inserts and these will drill through steel. You can do a quick check. Take a drill bit and, just by hand, see if it scratches the steel. If it does, then the drill bit is harder than the steel and you can probably drill a hole. If you have trouble drilling holes, consult a machinist. There are many factors which influence how well you can drill holes including use of cutting oils/lubricants, cutting speed, pressure, rake angle, etc.
Q:Ways to damage steel?
Your best bet would be a grinding wheel attached to a small electric motor. Even if you slipped, your skin is too soft to be cut by the dull wheel. Steel, however, is easily cut. But perhaps you don't have access to electricity or pressurized air to run such a tool. In that case, a simple file would work well, though you'd be somewhat more likely to injure yourself. If you had no tools, but access to whatever chemicals you wanted, you could try a weak acid. This would take a long time, and require constant scrubbing to bring fresh acid into the pits in the metal, but it would eventually eat through the collar.
Q:Several reading methods of steel tape measure
Direct reading method when measuring the steel tape zero scale alignment measurement starting point, proper tension (stretching force with steel tape tension or tension on the calibration ruler identification shall prevail, with the spring balance measure), direct reading measurement end point corresponding to the scale scale.
Q:How is steel coloured?
Steel can be plated(Chrome),Blackened(Black Oxide),Powder coated(color of your choose).All of this is done to prevent rust.All of these aforementioned processes can be worn off through being used.I suggest polished Stainless steel.
Q:what is brass and steel used for and why?
By instruments do you mean musical instruments? Brass is used for musical instruments because it's strong but very malleable. It's easy to hammer and roll into sheets, or form into tubes and complex shapes. It's easy to work with using hand tools. It's also very corrosion resistant and polishes very well. It has an attractive gold-like color. It also has some effect on sound, though the shape and design of an instrument is much more important to the sound than the material that's used. Apart from musical instruments, brass is used for items that need to be both durable, easy to manufacture, and resistant to the elements. For example plumbing items like valves and screw couplings.brass is a lot easier to cut with machine tools than steel. It's also traditionally used for hardware on doors and cabinets because of it's color, low friction properties, and corrosion resistance. Brass also is toxic to bacteria, and so brass doorknobs disinfect themselves after about 9 hours. Steel is very strong and very cheap. Steel is basically iron with a small amount of carbon added which makes it much stronger. Iron is the fourth most common element in the earth's crust, after oxygen, silicon, and aluminum. Brass being a mixture (an alloy) of copper and zinc, with other metals sometimes added. Copper and zinc are the 27'th and 26'th most common elements. Therefore, it make sense that brass is much more expensive than steel. Steel is used for too many things to be listed. The use of steel technology has impacts on almost every aspect of modern life. Nearly all of the man-made objects you touch on a regular basis were made using steel tools and steel machinery.
Q:damascus steel knife making?
Here's what you need, the cable should be a minimum of 9/16 with large wires. You need some borax (20 mule team from the store). A good hot coal, coke, or gas forge. If the cable has fiber rope in the center it will need to be removed. Fuse the ends of the cable to keep them from coming apart. I use my welder and while I'm at it I weld a handle to make it easier. Heat it in the forge when the forge is properly heated, rotate it. Some people will burn the oil out, but I've found that the forge does that just fine. Rotate the cable while it's heating. When it begins the turn red pull it out and sprinkle the borax over it, don't hold back use a lot. It will begin to melt and bubble into the steel. Put the cable back in the forge, rotate and watch. This is the critical part. When the steel starts to turn from orange/yellow to almost yellow/white take it out and lightly (I use a 2lb hammer) begin hammering the cable into a square or rectangle. If you do it right you'll notice that it will begin to fight the hammer, that's when you know the weld it taking place. You'll have to repeat the process down the length of the cable. Once you have the billet made you can begin the process of shaping the edge and tang. Once you have it shaped, follow proper forge procedure then grind all the yuck off and finish shaping. Then harden and temper and finish it out. Good luck. I almost forgot a very important part. Befor you start hammering put the cable in a vice while at welding temp (if you are strong you can use a couple of plyers) and twist it tight. On the next heat hold the cable in your left and and lay it on the anvil. Concentrate on your light hammer blows being on your side of the cable. This forces the cable strands together. If you are using smaller cable like 9/16 you can double the cable up and weld two peices together, it is easier and makes for a prettier blade. Doing this you don't have to worry about twisting the cable and you can hit it much harder to start with.
Q:stainless steel properties??
Stainless steel is a generic term for a whole range (there are more than 60 types) of Fe-Cr alloys. They all contain some amount of C and some alloys include a good number of other alloying elements. In almost all cases, the materials have corrosion resistance due the Cr atoms that are in solid solution with the Fe matrix. Under corrosive conditions, the Cr forms a thin tight coherent layer of Cr-oxide. This Cr oxide coating prevents further corrosion so long as it is not chemically or physically removed. If the SS has been subject to mechanical abrasion, the corrosion resistance can sometimes be restored by a light exposure to nitric acid which passivates the surface, restoring the Cr-oxide layer. The carbon content is an important factor in corrosion preformance but so is the heat treatment. Under the wrong conditions and in different environments, all SSs can rust. One of the most common corrosion problems is sensitization which occurs in the heat affect zone (HAZ) around welds. If the C content is high enough and the heat is high enough, the Cr atoms in solid solution form Cr-carbides and are no longer available to form a protective Cr-oxide. The corrosion resistance can be restored by appropriate heat treatment.
Q:Methoding - Steel Castings?
It is very difficult to define Methoding of Steel castings by one sentence. Actually it encompasses the total casting process. Normally it would mean a) Pattern design i.e. what type of pattern it would be- wooden, metallic, split or full, loose or fitted on a match plate or any other, how will be the parting line. b) Design of the gating system. c) Design of risering i.e. numbers, size and location of risers. d) Design of molding process i.e. sand system to be used, mold box size. But to do justice to the above mentioned activities, you need to consider other parameters of the casting process such as chemical composition, solidification characteristics, pouring temperature, pouring time, knock out time etc. As I said Methoding of Steel castings means designing of the total casting process from inception to final product.
