  1. Hello, I am an acupuncturist who goes through a good quantity of surgical stainless steel needles, likely 316 or 304? Currently I have to send these needles as biohazard material to a certified waste disposal company. I am looking for ideas on how I could possibly repurpose this material for potential art projects. I understand that SS is difficult to melt, so casting may not be an option. I also understand that any use of this material would have to include sterilization because of the biohazard nature of the waste. My initial thought was that melting the needle would take care of that aspect, but the more I read about SS, melting does not seem like a great option. I would appreciate any idea that you may have. I kind of tripped into this forum, so maybe I am not in the right place. I also have zero experience with metal work, so I do ask for patience. Thank you so much.
  2. i am looking for a quick list of the melting point of the metals used in blacksmithing and an easy way to remember them can anyone help?
  3. Hi all, I'm a relatively green blacksmith/knifemaker with a bit of query that I hope you can help me with. I recently started using proper coal (anthracite) in my forge having before used charcoal and the increase in heat took me by surprise. Under a fast blow the coal managed to melt the 01 steel bar I was hoping to forge out into a blade in half! Now I'm not overly familiar with the rules of decarburization but from what I've gathered if the heat oxidises over critical temperature the carbon "leaks" from the metal. Now I went ahead and forged out a blade from the remaining stock but my question is this: Being that the steel has been melted (and then obviously heated and beaten several times to forge to shape) upon heat treat am I just going to be left holding a sharpened piece of mild steel? It sounds like a foolish question even in my head but I have to know whether going through the HT process is worth it or if I should just chalk it up to lesson learned. Any advice would be greatly appreciated. Cheers RaptureRaptor
  4. I am very new to melting anything but I have looked up a lot about it but still need some help, I am trying to melt some cans I can only melt one can at a time becuase I have to smash them very small. I tried to melt one today with my homemade foundry the thing I'm melting it in is an old 9 ounce co2 tank one that you would use for paintball, I cut the top off of it to put stuff in the bottom of it is round. So today I put my soda can into it and left it for about one hour and it was still the same just red hot, so I took it out and tap it with a hammer and it just went flat like a ball of paper does it not melt to a liquid? But before any of this I put 2 small parts of a knife that snaped in half its stainless steel, it was in there for about 5 or 6 hours and still did not even move everything was red hot but no melting. What am I doing wrong? Here is my foundry, its an old cast iron tea kettle its very heavy and strong and I put a blower on the opening it works really good better then I thought it would, it stays red hot. So I just need some help to find out what I am doing wrong and what I can do better.
  5. i have a fair bit of copper pipe and wire, as well as some bars, with cold shuts in the sides and i am planning to melt it all down, how should i go about this? i am planning to make a trough of angle iron with the ends welded up, will this work? are there fluxes needed? many thanks monty
