Brazing brass using brass filler rods - Bladesmith's Forum Board
2012年7月26日 · Brass brazing is used to join together metals that have a higher melting temperature than that of the brass itself. Not saying that it cannot be done but, you would need to know the exact composition of each alloy (and thus the melting point) that you are working with. Your best chance of success is to start with a big enough piece of brass.

Forging brass, copper and bronze - Bladesmith's Forum Board
2012年5月8日 · It depends highly on the alloy. Copper and brass generally can be forged. Traditional tin bronze can't, as it's red short (increasingly more brittle as it gets hotter). Tin bronze with around 17-20% tin (bell bronze) can be forged between 600-800°C. The latter is extremely brittle if cooled slowly, but strong if quenched.
Help Needed: High Temp Salt Composition and Maintenance
2021年10月23日 · Same with the graphite rod. I realistically fire these 4-5 times a year at most, but they’re still running absolutely fine 20 years later. I think I effectively changed the high temp salt once, mostly to fish out a dropped blade. I use Brownell Nitreblue for the low temp. Also inexpensive, and carries its own risks.
Melting copper - Hot Work - Bladesmith's Forum Board
2004年7月9日 · Rio Grande sells some pellet for deoxidizing melts and I think they contain phosphorus. They work great, but I have also heard that you can add copper fittings to a copper melt and accomplish the same thing because they are made of phos copper.
Heat Treating W-1 - Bladesmith's Forum Board
2015年12月10日 · To harden: 1475°F for 10 minutes, quench (brine) or (brine for 3 seconds then oil) or (Parks 50 at room temp) or (canola at 130°F) Once able to handle at room temp, you can check your file test, but be sure there will be a decarb layer to get thru, especially if unprotected during all that cycling. Max hardness after quench will be 66-67.

I REALLY Need Help With 5160 Steel Heat Treating and Tempering
2012年1月28日 · Test all the blades that you make for proper hardness before putting a handle one the knife, unless you like to remove handles to re-heat treat if it didn't work the first time. Put a rough edge on the blade and see if you can cut into soft …
removing the valve from a propane tank - Bladesmith's Forum Board
2009年7月18日 · I bled the tank and unscrewed everything I could. I took out the actual valve parts as opposed to getting the whole valve off. I could run a welding rod (cold of course) into the tank itself. and I filled it with water very slowely as the hole is very small using a hose . I then used a gas cutting torch to cut off the top.
Heat treat oven?? - Bladesmith's Forum Board
2019年1月17日 · The pros are that they heat the blade very quickly and evenly, prevent all scaling, and offer the option of "high temp quenching". And by that I mean that you can quench into a pot of salt at something like 600F, quickly beating the nose of the TTT curve, but then take your time to straighten any warps and generally gently cool the blade during ...
