Where and how did you perform the hardness testing? 2. Did the furnace contain a protective (reducing) or inert atmosphere to prebest 4130 steel hardeningI was in our lab. We have a rockwell hardness tester. Yes, it did. I meant 4130 not 4103I would suggest you remove a sample and have a metallographic examination performed to verify your heat treatment process. This examination will debest 4130 steel hardeningI was looking for the proper times and tempatures for this process. I have the certs that it is 4130.Your austenitizing temperature of 1600 deg F is ok, the furnace soak at temperature should only be 30 minutes ( at 1600 deg F for 30 minutes) not 2best 4130 steel hardeningThank you, I'll try this tomorrow.I'd say that a 700F temper is a tad high for your required hardness. I would suggest 450F for one hour.Instead of quessing you can use MIL-H-6875 which can be found at http://assist.daps.dla.mil/quicksearch/An additional source of this data - not free however - is the ASM Handbook Volume 4 Heat Treating.
