DocDrew Posted September 9, 2008 Share Posted September 9, 2008 I know this is a tool, and not a blade, but you guys are really the masters at tempering, so,,, Just built a quickie wrench out of an old truck spring (leaf), guessing 5160, what's the tempering temperature, and what's the quench? Thanks, Drew Quote Link to comment Share on other sites More sharing options...
Rich Hale Posted September 9, 2008 Share Posted September 9, 2008 Dont want to give you a short answer when there is a bp on here that will be a good shop reference for this tool or almost antying you make in the future..Bp0078 Quote Link to comment Share on other sites More sharing options...
Tim92 Posted September 10, 2008 Share Posted September 10, 2008 I have read to fully harden 5160 you need to temper at 475FBladesmith's Forum Board > 5160 Tempering Third post down hope it helps Tim92 Quote Link to comment Share on other sites More sharing options...
ThomasPowers Posted September 10, 2008 Share Posted September 10, 2008 WARNING that site/post is with respect to making blades of 5160 you do not want a tool to be as hard and brittle as a blade! You will almost certainly want to go higher in temp that a blade temper to get a spring temper. Quote Link to comment Share on other sites More sharing options...
Rich Hale Posted September 10, 2008 Share Posted September 10, 2008 Just a quick point here...You do not harden steel by tempering.. Steel is hardened by heating to a specific heat for a set period of time and then quenched by cooling. Some steels quench in air, some in oil, some in water, and some in brine. Tempering is a process of heating to a specific temperature for a set amount of time to take away some of the hardness. The bp I refered to above covers this better that space allows for in here..
