4130 steel heat treated hardness Introduction

heat treating 4130 steel - Metal and Metallurgy ...

Feb 25, 2005 · RE heat treating 4130 steel. 23 Feb 05 14:25. 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 2 hours. Immediately quench in oil (this is most important to perform as rapidly as possible).

Two questions; 1. Where and how did you perform the hardness testing? 2. Did the furnace contain a protective (reducing) or inert atmosphere to prevent surface decarburization during heating and soaking at 1600 deg F?I 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 determine if you had achieved a thru-hardened, quenched and tempered microstructure. I would also confirm the chemical composition of the stock to make sure it was 4130 alloy steel.I 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 2 hours. Immediately quench in oil (this is most important to perform as rapidly as possible). Place back in the furnace at your original tempering temperature of 700 deg F for 30 minutes (at temperature), remove from the furnace and cool to room temperature. I don't have immediate access to my reference material to confirm the 700 deg F tempering temperature, but off the top of my head it appears to be about right for your required hardness range.Thank 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. This gives an austenitize recommended temperature of 1500 - 1600 F Water Quench Temper at 400F gives around 47 Rc Temper at 500F gives around 45 RcWhen they did the Rockwell testing was the sample lying flat, in direct and complete contact with the anvil? Any bow or gap will produce a wildly soft reading. Testing hollow sections is trickyAISI 4130 heat treatmentAug 07, 2016Post Weld Heat Treatment of 4130Mar 19, 2010See more results

I've milled pre-treated 4140 at 550-1200 sfm with good milling grades. The harder ones (over 38Rc) needed the slower speeds, but the more-common heat treat of 28-32Rc can run quite fast.
