heat treating 4130 steel - Metal and Metallurgy ...

eng-tips› …› Metal and Metallurgy engineering ForumFeb 25, 2005· I tried to heat treat a piece of 4103 steel .125 thick 6 inches long shaped like a "u". I put the piece in the furnace at 1600 degrees for 2 hours (the oven was preheated), then oil quenched, and anealed at 700 degrees for 1 1/2 hours.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 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?

4130 Oven Heat Treat - Heat Treating, general discussion ...

Apr 24, 2013· 4130 is popular for bicycle frames (and aircraft frames) primarily because it doesn't demand heat treating post-welding. You can also get work hardening stress from bending. This 450-500° heating would relieve some of the bending stress but I'd guess a 7° bend introduced next to no stress.[PDF]
