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:Stainless steel laminate?
There okorder.com appliance paint 2. What you are referring to really is not laminate steel sheets, it's actually more along the lines of shelf liner paper looks like steel with sticky back film that you peel and stick. Place against product and begin to peel down slowly using squeegee or credit card to smooth out bubbles.Sheets can be purchased rangingin size on OKorder for $9.99 + dependent on size. Called stainless steel appliance film can buy a roll for $60.00 on OKorder (normally sells for $100.00) one roll will cover 3 average sized kitchen appliances. Hope this helps!
Q:where did WTC steel go?
Some of the steel was recycled for sale to other countries where they aren't so picky about reusing building materials. NIST had 200 pieces of the steel for their investigation, which they returned last year. This was covered in the press. The rest of the steel was held at JFK international airport's Hangar 17. Much of it will be placed/has been placed in the new museum beneath the Memorial at the WTC site. Thousands of pieces are being given out for 9/11 memorials all over the world. Just about every day you read in the newspaper about another piece going here or there to this city or that city. Yes, a lot of the steel was tested for a number of chemical compounds. It had to be for safety reasons before storing it and giving it out. Depending upon what countries the recycled beams were sent to and their rules, it was sometimes tested at the ports of entry over there, as well.
Q:why do you heat steel when hardening?
Halps is off base a little. The reason heat is involved in hardening of steels depends, a little bit, on how you are doing the hardening. If you are hardening by work hardening, you do not have to heat it at all. If you are barbarizing (case hardening), the temperature is raised to increase the diffusion rate of carbon into the steel, higher C content - higher hardness. If you are Thur hardening, you have to heat the steel to the austenitizing temperature (so the structure transforms to FCC crystals with higher solubility for C) and then quench it (cool it rapidly enough to freeze the C atoms in the martensite crystal structure). If you slow cool, the steel could end up softer than it started. All of these processes involve atomic level things. If you want to understand them on the atomic level, you need to study physical metallurgy of steels. It is a subject onto itself and is really quite fascinating if you are interested.
Q:how strong is carbon steel?
You need to be very careful when selecting a sword. Most f the sellers are lying about their swords. If we were talking about tow 400 year old swords you could bet that the folded steel blade would be the better. Today many rip-off sellers put that in the advertisement to get people that don;t know any better to buy their sword. Many new swords that are not folded are as good or better then folded. your best bet is to buy only from a reputable seller. There are two I know sell good swords Bugei Trading and Cheness. I like cheness because the swords are reasonable in price and very well made. Expect to spend at least $220 to get anything worth buying. Cheness has a line of swords Katana that are made of spring steel. Note: carbon steel varies greatly depending on the exact steel used, it carbon content (how much carbon), and how the sword is made and tempered. Many of the rip-off swords are made of carbon steel, just low quality steel and bad workmanship. ...
Q:Steel Strings or Nylons?
Steel because I bought a steel string guitar and that's what goes on it. Had I bought a classical guitar I would put nylon strings on it, but I don't particularly want to play classical guitar music, so I bought a steel string guitar. That's my story and I'm stickin' to it!
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:what is the difference between white steel and blue steel in reference to sushi knives?
This Site Might Help You. RE: what is the difference between white steel and blue steel in reference to sushi knives? looking to buy a sashimi knife. what is the difference between white steel (1and2) and blue steel (1and2) in terms on characteristics. what gets sharper? what holds edge longer? basically any info on the pros and cons of each steel would be SO GREATLY APPRECIATED! thanks in advance to all who...
Q:Structural steel architecture?
if u need to analyse a steel framed structure for joint details the best example would be of a mechanic workshop...the truss of such a workshop is always supported on a portal frame and in most of the case thats a steel structure...do keenly observe the joints at the footing plates that is connected to the girder section...nd also observe the joints in truss of such a frame....myslf m a civil engg. student.
Q:Is Damascus Steel Fake?
damascus steel it says is made from ore containing either tungsten or vanadium, although most tools I've seen are made from chrome vanadium, it wouldn't be hard in this day and age to get the proper material. Although it DOES say in wikipedia that apparently the technique died out a long time ago due to shortage of the ore. Then it talks about reproduction attempts. So theoretically, yes, it could be the deal deal. But it does refer at the bottom about damascend steel which is made with a different technique, you could be buying one of those. NEXT TIME JUST LOOK UP THE ARTICLE YOURSELF AND READ IT
