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 content of kitchen knife any good?
I am a former chef and have used Chinese chefs knives, different types from cleavers, even french knives, they are mostly carbon steel, and are made with a cold forged process, they are as good as the European knives and are marketability cheaper, I have one a french knife a 8 one with a green non porous handle. I like it, it is light weight and very well made, and keeps an edge quite well, just look for the better type available.
Q:Does steel make its own static electricity?
If you sprinkle iron filings near a bar magnet (on paper, etc.) the filings will try to line up with the magnetic field (because iron atoms behave like tiny magnets). Bringing the compass near steel (mainly iron with a little carbon) will cause the iron to try to align with the magnet of the compass needle, however, because the needle is free to swing it also aligns with the magnetic field set up between the needle and steel. Any static electricity would have nil effect on the magnetic field.
