- Q:What is a better knife Cold Steel VS SOG?
- Look up a knife maker called Bench Made, the knife i recommend is the CQC7 its a tanto tip half serrated blade all low glare black folding with pocket clip. it has one of the hardest steel blades. You need to learn about steel hardness the harder the blade the sharper it can get and the harder the longer it will hold a edge. but hard steel can get brittle it can snap now as softer steel will bend and dull quick. the bench-made CQC7 goes for around $100 or that ball park...enjoy read some about the knife and think about what you want it for....my CQC7 can cut a coat hanger by pulling the serrate across the hanger!!
- Q:what is stronger Tempered Steel Blade or Carbon Steel Blade?
- 1. all steel blades are tempered, whether they are high carbon blades or low carbon blades. 2. It depends on what kind of steel they are made from. So im going to answer this question, using the following qualifications. 440A stainless steel 440C stainless steel - high carbon. The higher the carbon level, the more brittle a blade becomes. But the higher the carbon level, will increase a steel’s wear resistance , meaning it will have a better edge retention 2. They both will work well. Pros's / Con's The 440C blades will need less sharpening, but are harder to sharpen The 4401 blades will need to be sharpened more, but are far easier to resharpen. So it basically comes down to where you will be using them and how you will be using them. If your gonna be out in the middle of the jungle and stopping for the night, then the high carbon blade would probably be better, you use it all day, resharpen it at night. If your gonna be cutting brush, tobbaco, etc on your land, then the 440A would be better, because you can take a couple of min's to resharpen it often
- Q:whats the benifits of using steel material for fasteners?
- There are different grades of steels which can suit different application considering corrosion,surrounding atmosphere,pressure,temperature and many more. Let us take the stainless steel fasteners: 1.Resists Rust: The primary advantage to using stainless steel bolts is that they resist rusting. This makes them ideal for outdoor or marine uses, since moisture will not cause them to corrode. Rust basically eats steel and makes it weaker. A rusty, weak bolt can be a serious safety risk, because it can break under a load. 2.Clean: Stainless steel bolts are very easy to clean due to having a higher content of chromium, which creates a lustrous, mirror-like surface that is very smooth. This makes stainless steel an ideal option if aesthetics are an issue. 3.Temperature: Stainless steel has a high melting point, which makes it a good option in machines that are put through immense amounts of heat. The bolts will not fuse together, and can be unfastened when the machines need repairs. Also, in very cold conditions, steel can become brittle. By mixing nickel into the stainless steel, the metal resists becoming brittle at low temperatures. See the source link for details.
- Q:Are the shafts on my clubs graphite or steel....?
- Hold one club in each hand and hit them together like swords fighting, putting the impact point about midway down each shaft, and listen to the sound. If it's more of a clank sound, it's steel, and more of a click sound, it's graphite.
- Q:How to wear out stainless steel?
- Its called stainless for a reason :) many grades are out there, 300 400 series. You could use acid to make it look older but you wouldnt want to cook with it after chemically converting it with acid.Personally i like cast iron. It will last a life time + and looks very cool. Sorry no safe way to do it and cook with it. B^
- Q:whats the difference between weld steel and sheet metal?
- galvanized steel gives off poisonous fumes when you weld it
- Q:How does the reactivity of iron compare to steel?
- Steel is an alloy of iron and carbon and optionally one or more of numerous other materials. Copper is normally not used, except sometimes in small percentages. Steel is never yellow or orange in color. Reactivity of steel depends on the materials it is alloyed with. Chromium and nickel with steel make stainless steel, which is much less prone to reactive than iron. .
- Q:Does steel give off harmful gas when heated?
- Steel often has impurities that can generate fumes, which cause a fever identical to smoke inhalation. You always need to be concerned about what you are breathing around hot metal.
- Q:Can you give me the general working and description of a steel cooling bed?
- Another type of cooling bed is used for square stock. It consists of several beams with angles cut upward from the bottom. The beams move in alternating fashion so that the square beam is lifted and sat into the next 'tooth'. The angle is cut so that the beam rotates as it is set down. This keeps the stock straight while it cools.
- Q:1 inch thick steel target good for mosin?
- it depends on the type of steel. If it's soft steel it may stop the round, but leave a craterthat can causeirregular ricochets. If it's hardened steel (AR500 for example), the bullet will just 'splash' and fragment into little bits. It's better to shoot thin steel so the round goes through than shoot thick soft steel thatforms a crater. No matter what type you're shooting, put it no closer than 100 yards for a full power jacketed round. Try to hang the plateso it is angledslightly towards the ground so anymajor ricochets are directed into the ground and not up or back towards you.
