Q:Do they manufacture steel buckshot?
Steel shot is used for hunting migratory waterfoul. Since buckshot is inappropriate for waterfoul hunting , it is not manufactured. Steel is less dense than lead and for the purposes for which buckshot is appropriate, lead is permissable and is more efective. There is no need for steel buckshot.
Q:What type of steel is most bullet resistant?
If you want to stop a bullet with steel, you need strength, ductility, thickness, or some combination of these. The higher the strength, the greater the force the steel can withstand before it breaks. The higher the ductility, the more the steel can deform before it breaks. Unfortunately, when you increase the strength, the ductility usually goes down. That's why you may need substantial thickness. 1 centimeter of precipitation-hardened stainless steel (15-5 or 17-4, for example) is probably enough to stop most handgun bullets.
Q:How to restore rusted stainless steel?
Stainless steel doesn't rust, whatever acid you got on it was some pretty bad stuff to make a reaction like that, you can try sanding down past the reaction point and polish it out but that's about it, that or it wasn't stainless to begin with. if its brushed chrome to simulate stainless it would have to be replated, not cheap. and probably not worth it
Q:what is best cookware? stainless steel or iron?
Some utensils are both cookware and bakeware. The choice of material for cookware and bakeware items has a significant effect on the item's performance , particularly in terms of thermal conductivity and how much food sticks to the item when in use. Some choices of material also require special pre-preparation of the surface - known as seasoning - before they are used for food preparation. Stainless steel cookware is a great choice for safe cooking. Many kinds of cookware react with the foods, either changing the taste of the food or even releasing harmful materials into the food that can cause imbalances or diseases. Many non-stick coatings like teflon are safe - but once they get scratched or overheated they can start to leak chemicals in the food that are according to some scientific studies dangerous and possibly carcinogenic. Both the cooking pot and lid handles can be made of the same material, but will mean that when picking up or touching either of these parts oven gloves will need to be worn. In order to avoid this, handles can be made of non heat conducting materials, for example bakelite, plastic or wood. It is best to avoid hollow handles because they are difficult to clean or to dry.
Q:are steel guitar strings ok? :)?
Nylon strings aren't better The very notion of such is absurd. They're different. They sound different and feel different. Different guitars are designed for different types of strings. Nylon string guitars are most commonly associated with classical music (you'll never see a real classical musician play a steel string guitar) Whoever told you that nylon strings are better should be ignored altogether. They're obviously not a good source of information.
Q:is alloy steel is same with stainless steel?
Alloy Steel Vs Stainless Steel
Q:what steel is best for a survival/utility knife?
INFI steel used by Busse Combat is probably one of the best steels around right now, but the price reflects that. The heat treat is a HUGE part of the toughness of a steel. A good heat treat can make a bad steel a good one, or a good one a great one. I personally prefer 1095. It's a good ole tool steel on the lower end of the price scale and it holds up well. I've always had good experiences with 1095.
Q:Can steel dive deeper into sun?
Dont understand are you going to put them in sun ? Sun made from gas wich is on fire. Its impossible to get to the sun and not to get burn. Steel is really more solid and strong than iron so its more hard to break it or to bend. But in camparing of fusion temperature - iron is a bit more better, though it would not make a big difference .From metals - tungsten has the highest fusion temperature - near to 3400 C . Iron is near to 1530 C, steel is near to 1300 -1500 C. So according to this tungsten can go most close to sun. Right near the sun temperature is millions of degrees so anything will fuse and burn there.
Q:Acoustic Guitar Strings? Nylon vs. steel?
Steel strings sound much better as in brightness and tone. Nylon strings sound dull and don't hold tune well but are easier to press. You need to build calouses on your finger tips and using steel will do this, just take it easy until they form and stop when they start hurting moderately. When you put new strings on a guitar, it's very good to break them in by pulling on them from the neck upwards to stretch them out. If you don't, you will need to tune them much until they wear themselves in. Good luck and make some sweet music !!
Q:shinning ammo with steel wool?
You could, but if you have access to a vibrating case tumbler, it would work much better. I just tumbled a batch of 1,000 of tarnished and dirty Romanian 7.62X25 and it now looks like brand new commercial ammo.
