Q:Can stainless steel cut well?
There are many kinds of stainless steel. 440c, 420j, ATS34, and so on. Cold steel uses 420 type steels in several of their products. High carbon stainless steels cut well but edge retention is not very good but that also depends on the heat treating of the metal. I could go on all day but very, very basically stainless steels lack the shatter resistance necessary when stretched to great lengths. This is in part why other steels make far better swords. The stuff sold on QVC is just plain junk. Do not buy a stainless steel sword. A blade made of 440S means it belongs hung on a wall...
Q:About types of stainless steel for knifes.?
The two main ingredients in knife steel are carbon and chromium with some extras that have varying effects on hardness and toughness. Aus8 is similar to 440A stainless with less chromium which would make it a little stronger. I've tested aus8 blades and wasn't real impressed with its edge holding compared to even 5160 carbon steel (the lowest grade I use).
Q:buying Stainless Steel refrigerator?
It's not about color necessarily. Stainless steel is easier to clean and for the most part scratch resistant. It's easier to take care of.
Q:Is boron steel harder?
The only thing that affects the hardness of steel is the carbon content. But there are many elements that can make it easier for a steel to achieve its maximum hardness. And Boron is an extremely effective element that increases the hardenability of steel. Adding as little as 0.002% Boron can have a big impact upon quenching of a steel. Boron is usually added when you need the hardness of a heat treated steel part to extend deep below the surface. For example, lets say you had a two identical plain carbon steel parts, but one had boron and the other didnt, and you wanted to heat treat them both After quenching, the surface should be the same on both, and lets say its 55 Rockwell C. In the plain carbon one, the hardness might drop down to 50 at 2mm under the surface, but the boron treated one might not drop to 50 until 4mm under the surface. Now, these numbers were completely made up, and it would depend on the specifics as to what the difference might be.
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:Pistol Polymer Frames? Good as Steel? Walther P22 OK?
All polymer frames are cast around steel 'skeleton' inserts, which bear the stress and wear between receiver slide, as well as other wear points. The great advantage to polymer frames is the lower weight over the polymer composite compared to an all-steel or other metal alloy receiver frame. As all wear contact points are 'steel-to-steel', the service life expectancy of a polymer-frame weapon will be the same as an all-steel frame design. NO polymer-frame design I know of has ANY stress or load contact points between metal and polymer-only surfaces. My polymer-frame H-K USP and my Glocks are constructed this way.
Q:Bendable steel for crossbow bow.?
So i do know way more about compound bows than I do about crossbows, but i'm going to enterprise an opinion. For my part, i would probably lean toward the compound bow. A part of it's only that i like them higher. However, moreover to that, more often than not when you find yourself hunting you will carry the crossbow loaded, on the grounds that the are typically awkward to load when you have the shot. If you're hunting from a blind or from a tree stand (and might figure out easy methods to load the item whilst you're up there) that's almost always ok. But when you need to tote a crossbow round whilst it's loaded, that may be a bit dicier proposition. Most crossbow safeties are lovely crude making the likelihood of by chance firing one alot bigger than with a rifle. Now, to the plus facet, a crossbow has essentially the entire upside of firing a rifle - best accuracy, same ergonomics, can run a scope on them. Without the downside - no real recoil, no longer too loud and you simply have a lovely excellent trigger on about any of them. Compounds are way more work. Plus it is much tougher to be accurate under stress with a compound than a crossbow. Regarding the protection? Don't particularly find out about that. After I was once doing shooting alot of archery, my 3 - D bow for outdoor stuff was once at ninety two pounds with a fifty five% letoff. My goal bow was once round 60. I had to pretty on the whole take care of string stretch, and tuning with the three - D bow. So i'd expect a crossbow to be in that regional. 5 hours to your nearest Bass pro? Good for a crossbow perhaps it's valued at it because no longer too many places raise them. Nonetheless, should you do back to a compound bow it appears rough to feel that would be your nearest archery professional shop. Thinkingblade

Q:what's the difference between natural rolled oats oatmeal and steel cut oatmeal?
Steel cut oats have health benefits. They are delicious and very good for you! The difference between regular oatmeal and steel cut oatmeal: Steel-Cut Oats are whole grain groats (the inner portion of the oat kernel) which have been cut into two or three pieces using steel discs. Golden in colour and resembling mini rice particles, they are as nature intended - nothing added and nothing taken out. Rolled oats are flake oats that have been steamed, rolled, re-steamed and toasted. Due to all of this additional processing they have lost some of their natural taste, goodness and texture.
Q:What's the difference between Stainless and Clear steel?
Stainless steel is different than regular (clear?) steel because is is an alloy, or combination, of steel and other elements. Stainles steel has 15% chromium, which is very resistant to rust than regular steel. That is why stainless is more expensive
