An old heat treat question
Yeah, I know it has been asked and answered but here it is again. What are the heat treat parameters for blade and spring for the following steels? ATS-34, A2, D2 and any other favorites for that matter. I have seen some very high tempering temps and am just curious about that. My favorite steels are listed and yes, it is a help for me. The spring treat is of particular interest. Thanks, Dave

www.crucibleservice.com will give you the HT for those alloys [ using 154CM data for the ATS-34 ]. While they show high tempering temps for ATS-34 blade makers use 400F ,that will work fine .

I actually have data on heat treat but the treatment of springs is of interest to me. That is where I have seen a difference in heat treat. I assume that makers heat treat springs a bit differently than blades

Working springs are heated and quenched just like a blade to get max. hardness, then drawn back to around 45 Rc, so they can flex a little without breaking. Not all steels will make a usable spring. |

I believe that 1095 is refered to as a "spring" steel. Wouldn't it be a bit simpler to work with?
Just a thought. Larry |

1095 is a great spring steel and was used by Bob Ogg for years. However, it is certainly not stainless. I have one friend that swears that ATS34 makes a fantastic spring. But regarding this steel, I have seen several heat treatments for spring use. It seems the initial treat is the same but the temper part is different for springs. And that was the question....

Sorry, didn't understand the question. Any steel that is used for springs can be called a 'spring steel'. Just drop the hardness down ,so for ATS-34 temper about 1000F.
