Q:is stainless steel plated or alloyed/mixed?
stainless steel is an alloy normally iron with additions of C, Mn, Ni, Cr, and Nb - amounts added depend on properties required. Corrosion resistance is due to a very thin but dense layer of chromium oxide which forms at the surface and prevents further attack. Ordinary steel on the other hand becomes coated with a porous layer of iron oxide(rust) through which the atmosphere can pass and cause further corrosion.
Q:How to restore rusted stainless steel?
Nope, stainless steel is actually coated steel that can be removed by acid or scrubbing too much. it would need to be re dipped to go back to normal. would cost a fortune however.
Q:How can the outer diameter and weight of steel coil be converted?
Of course, the calculation is relatively coarse, and the volume has a lot to do with the tension.
Q:Question about the strength of steel..?
If done correctly it should increase the tensile strength at least.
Q:is stainless steel and surgical steel the same?
This Site Might Help You. RE: is stainless steel and surgical steel the same? i need the same kind of body jewelry they use in the piercing shop but when i go to order them they say stainless steel, not surgical steel, and i have REALLY sensitive skin so i need to be sure, whats the difference?
Q:How to sharpen a knife with the stone and the steel?
The site listed above gives you a great step by step procedure on how to do this yourself. A Sharpening Steel is used to sharpen the fine edge of a knife. Many knives only need this done to have a refined edge. Any fine edge of a knife can have minor burrs that occur with normal use. To sharpen this type of edge, merely run the knife at an approximate 7-8 degree angle, away from yourself on the Sharpening steel repeatedly (no more than about 8-10 times each side, alternating each side as you go). Give the knife a quick wash, to remove any unwanted detritus, and you are ready to go. If you want to resharpen an entire knife, use a wet stone. Remember some stones have a natural oil in it, some do not. If you are already using a stone with oil, continue to use it with Mineral Oil as the lubricant. If it is a dry stone, use warm water. You'll never be able to change a stone once you use oil. Make sure its as flat as you can. Wet it with warm water, or the mineral oil, rub the knife away from yourself (on the coarse side) at a 5 degree angle on both sides. Alternating sides approximately 20-30 times each. Flip the stone over (dry finer side), and at a 6 degree angle, rub the knife blade toward you on both sides approximately 10 times on each side. Using either your Sharpening steel, or 550-600 coarse emory paper, rub the knife away from you 5-7 alternating times on each side at about a 7-8 degree angle. Clean the knife well. You now have a VERY sharp knife that will require this entire treatment ony 2-4 times a year at most. Otherwise, keep using the sharpening steel. I GUARANTEE this works best.
Q:Is Steel crystalline in its makeup?
Steel is crystalline. In general the bigger the crystals the better.
Q:Steel Arch Building.........!!?
i think a moment frame steel building with a parabolic arch from two corners with the top middle capstone looks pretty nice on four sides. on a plane view, the capstone forms a cross on roof top with a rectangular elevator shaft at middle and with several floors act as weight on the capstone. the four corners roof top floors have to have heavy columns reaching down to the foundation. then u draw a inverted V from the root of the arch to the capstone and filled the area between the arch and inverted V with trussed web members. this trussed arch can act as a wind bracing for the moment frame building. u have to investigate the proper angles for the trussed web members. if u set a vertical web member from the arch to the inverted V, that is at the largest gap and then build the truss web member from there. i would not only use one facade but double facade to increase the capacity of the building to resist vertical and lateral loads. however, the arch needs a tie beam to make sure the roots of the arch won't spread apart under compressive load and the load must be contain inside the arch. no one has build one like that yet.
Q:what caused my stainless steel sink to get rust spots?
Stainless Steel is the marketing name. For truth in advertising, it should be called Stain Resistant Steel. It should be easy to scrub rust away with an SOS or Brillo pad. To prevent rust from recurring: * thoroughly rinse all chloride containing soaps away * scour the sink at least weekly to remove any residues * if the water source has high mineral content—especially iron—more frequent sink scouring is needed, plus towel drying the sink. * don't allow salt to remain in the sink—rinse it out
Q:question on shotguns and steel...?
Damascus steel in gunmaking Prior to the early 20th century, all shotgun barrels were forged by heating narrow strips of iron and steel and shaping them around a mandrel.[22][23] This process was referred to as laminating or Damascus and these barrels were found on shotguns that sold for $12.[22][23] These types of barrels earned a reputation for weakness and were never meant to be used with modern smokeless powder, or any kind of moderately powerful explosive.[23] Because of the resemblance to Damascus steel, higher-end barrels were made by Belgian and British gun makers.[22][23] These barrels are proof marked and meant to be used with light pressure loads.[22] Current gun manufacturers such as Caspian Arms make slide assemblies and small parts such as triggers and safeties for Colt M1911 pistols from powdered Swedish steel resulting in a swirling two-toned effect; these parts are often referred to as Stainless Damascus.[24]
