Q:Damascus steel knife?
Pattern welded /damascus is too expensive to use as an everyday knife, as it can cost more than silver. It's best kept as a collection piece. You'd be stupid to keep it in your pocket or use it everyday. that would be a waste of money. Knives you use everyday might be lost or stolen, or they may get rusted, worn, or dirty..... ruining their value. From that point of view the strength or edge-holding ability means very little. Specifically, the bushcraft knife is pattern welded steel. True damascus or Wootz steel is something you'll only find in museums and private collections. they stopped making it several hundred years ago. Despite what many people have claimed, Wootz damascus was inferior to modern tool steels in every respect. It was a brittle, dirty material. It's legendary status has more to do with myth and storytelling. The reason they stopped making was undoubtaby because more modern methods came along that produced a more consistent product, more quickly and easily. Old technologies tend to be abandoned for good reasons. With pattern welded steel, about a dozen strips of two different grades of steel have been stacked, welded together, the twisted and forged to create interesting patterns. This more of an artistic process and doesn't improve the properties of modern steels. Pattern welded steel is for the most part, inferior to a homogenous blade made of a single grade of steel. First of all, PW is a handmade product which means there will be faults and oxide inclusions incorporated into the steel. The welding process is not perfect. Secondly, in the hardening and tempering process you end up with a compromise between the properties of the two different grades of steel. You end up with a product that is not quite as good as either steel would have been individually. The blade may either be too brittle or too soft.
Q:how do you rate the hardness of steel?
Find your portable hardness testers from our latest collections thats for sure having the ability to test hardness of metal alloys and plastic by applying some amount of pressure on it. All our evaluators can evaluate in Brinell, Rockwell and Vickers machines.
Q:what are some advantages of stainless steel?
313 times as resistant to rust and corrosion as mild steel. 30% stronger and more durable than mild steel. 15% more conductive than mild steel. Easily wiped clean. Scratches can be easily polished out.
Q:What is the Rockwell (HRC) Indentation Hardness of Steel?
The general purpose default steel for hard tooling applications is A2 It's cheap, readily available and comes in many different shapes and sizes. It's easy to machine soft. It's easy to harden, you can do it yourself. It is very dimensionally stable during hardening. All the steels mentioned above are specialty steels - expensive to buy, hard to work with, expensive to heat treat and dimensionally unstable during heat treat.
Q:how is steel made????????
That is an ENORMOUS subject that won't fit in this little box. Run an internet search on steel making. Essentially, steel is an alloy of iron and other metals chosen to give it the desired properties. These metals usually come from ores that are extracted from the earth. Actually, iron has too much carbon for most steel making purposes, and the carbon must be burned off. Iron is melted in a blast furnace, and oxygen is used to burn off the excess carbon. Then the molten metal is mixed with molten alloy metals and poured into molds to make ingots, which are blocks of steel of a size convenient for handling. Steel can also be made by re-melting scrap metal and adjusting the amounts of various adulterants or alloy metals at molten temperatures. The ingots are taken to rolling mills to be shaped into rods, pipes, sheet metal, and structural shapes. Molten iron and steel can also be poured into molds to produce complex shapes.
Q:CONNECTING STAINLESS STEEL TUBE (SOLDER?)?
Soft Soldering All grades of stainless steel can be soldered with lead-tin soft solder. Leaded solders should not be used when the product being soldered is used for food processing, serving or transport. Soldered joints are relatively weak compared to the strength of the steel, so this method should not be used where the mechanical strength is dependent upon the soldered joint. Strength can be added if the edges are first lock-seamed, spot welded or riveted. In general, welding is always preferable to soldering. Recommended procedure for soldering: · 1. The steel surfaces must be clean and free of oxidation. · 2. A rough surface improves adherence of the solder, so roughening with grinding wheel, file or coarse abrasive paper is recommended. · 3. Use a phosphoric acid based flux. Hydrochloric acid based fluxes require neutralising after soldering as any remnant traces will be highly corrosive to the steel. Hydrochloric acid based fluxes are not recommended for soldering of stainless steels. · 4. Flux should be applied with a brush, to only the area being soldered. · 5. A large, hot iron is recommended. Use the same temperature as for carbon steel, but a longer time will be required because of stainless steel's low thermal conductivity. · 6. Any type of solder can be used, but at least 50% tin is recommended. Solder with 60-70% tin and 30-40% lead has a better colour match and greater strength.
Q:Where can you get a thick sheet of steel?
Try a local Fastenal store, they can order it for you by the sheet. If that doesnt help, then try a welding or fabricating store.
Q:Steel Building Structures?
Which steel buildings are you asking about? The Empire States Building has a steel frame and is completely weatherproof. Most industrial factories have steel frames and are weatherproof. It is the cladding that makes them weatherproof. By the way there is a difference between weatherproof and waterproof.
Q:on pokemon diamond what pokemon are week to steel types?
Rock pokemon are weak against steel type moves.
Q:Are the shafts on my clubs graphite or steel....?
Most steel shafts are stepped, meaning there will be a series of ridges that run down the lengeth of the shaft every few inches. Also, take a piece of metal and tap the shaft with it. If it makes a ping type of sound, its metal. If it makes a clunk sound, its graphite. Or, look out the window and ask the first person you see walking by. Unless they are younger that 10 years old, they should be able to tell you pretty easily.
