Q:Is carbon steel strong?
Real katanas need regular maintenance, they rust easily and dull quickly. If you get a replica chances are it will break the first time you hit anything with it. If you can find one, the WW2 officers swords were of good quality and the modern metals mean it doesn't rust or dull as easily. If you do insist on getting a carbon steal blade be ready to oil it often. It will rust at the mention of moisture.
Q:Buy a steel building!!!!?
Before okorder.com/... Hope this will prove helpful to you.
Q:Question about steel studs.?
Steel studs are mainly for commercial applications on non bearing walls. 100 studs, must be one big assed bathroom. Do yourself a favor and install a pressure treated bottom plate, even if you use steel studs.
Q:manufacturing process of steel containers?
There are many types of steel containers and many different mnfg processes. There are also thousands of different steel alloys. Steel is used for canned food, compressed air cyclinders, hydraulic pressure vessels, electrical boxes, and many other containers. Steel containers are made out of sheet metal by soldering, brazing, spot welding, seam welding, riveting, bolting, screwing, etc. Heavier wall containers are fabricated of plate steel. Some steel containers are made by deforming the steel by extruding, forging, spin forming, drawing, ironing, etc. Some steel containers are made by machining. You should be able to find plenty of references if you search for these terms. good luck
Q:Welding Stainless Steel?
Yes you can use regular welding rods for stainless steel. But you will not have the properties of the stainless. The weld joint will have a different color than the stainless if you grind/grain/finish the weld. It could also rust. The joint could be weaker. It is best to use a rod that comes as close to the base metal stainless as possible. (30 years welding - certified)
Q:Damascus steel knife?
Ok, lets define what is Damascus steel. The modern Damascus is basically any steel that shows a pattern. Patterns are accomplished by 1. manipulating the crystal structure or 2. by combining 2 or more different alloys together. The blade you are looking at is referred to as a pattern welded blade. Damascus is only as strong as it's base components + heat treat and design. The strongest will be obtained by combining high carbon and low carbon steels. I do this by using steel cable. The patterns aren't real bold but are interesting none the less. To break it you must brake the hard steel and tear through the soft iron. The laminated stuff works the same way. For greater edge holding I use all high carbon, varying alloy content from simple carbon to chromium/nickle alloys. These are what you normally find in pattern welded blades. A fine pattern that has many lamination's crossing the edge will offer the best edge holding. Properly done one can get the DCE or damascus cutting effect where the soft layers wear away faster than the hard layers almost making the blade self sharpening. Is that blade good? Buy it if you like it, it won't compare to a well made hand forged blade but is much cheaper. sorry for the overload.
Q:Is diamond lighter than steel?
Diamond has half the density of steel but would make a terrible sword because it is not very tough. Toughness is a material's ability to resist breakage from forceful impact: Diamond has a toughness of 2.0 MPa·m1/2 and has a critical stress intensity factor of 3.4 MN·m−3/2. That makes it tough for a gem but are poor compared with steels. Plus diamond has a cleavage plane.
Q:steel shafted fairway woods...?
If your club has a graphite shaft in it and you want to switch to steel an option is to get a dynamic gold lite shaft. The other option is to make sure you trim the shaft to the 42 length with the gold shaft to lighten up the swing weight. You can get away with about 42 3/4 with the lite shaft. I have found steel to be very consistent in my fairway woods and don't think I'll ever go back to graphite. I have mine cut to 42 1/2 for the 3 wood and 41 1/2 for the 5 wood with Dynamic gold s300 and they're fine.
Q:Damascus steel sword question?
There okorder.com, the true Damascus is a region of spain, which is similar to getting swords made in Pakistan
Q:Help! I did something to my stainless steel ring?
I would first check it with a magnet. If it is attracted to the magnet it has too much steel in it and that is what oxidized,not the CR. U might try to clean it with a good acid .
