How to Heat Treat A36 Steel Career Trend

How to Heat Treat A36 Steel. A36 grade steel is considered low-alloy; however, because the carbon can range up to 0.29 percent at the most and mild steel is anything below 0.25 percent, A36 is considered the safest mild steel. As such, direct heat treating is not applicable. Case hardening is the process for treating A36 steel.

Heat treating A36 steel rings - Metal and Metallurgy ...

Jun 27, 2008 · Heat treating A36 steel rings. A36 has a max carbon content of about 0.28%, which would produce a maximum theoretical hardness,assuming 99.9% martensite transformation, of about 52Rc. Since it is unlikely that his quench is that effective, I would venture a guess that he would be lucky to achieve an as quenched Rc hardness in the mid 40s.

Limbowhale, This guy is pulling your flipper. The maximum hardness of steel is essentially a function of the carbon content. A36 has a max carbon content of about 0.28%, which would produce a maximum theoretical hardness,assuming 99.9% martensite transformation, of about 52Rc. Since it is unlikely that his quench is that effective, I would venture a guess that he would be lucky to achieve an as quenched Rc hardness in the mid 40s. You are using a far better material for the reasons you indicated. your material is also much tougher and would resist chipping and fracture of the gear teeth.But his customer is carburizing the steel - doesn't that increase the carbon content near the surface?Yes 4340 is better material than A36 in a head to head comparison. I don't know the application and what durability is required, but if the customer is to get the most out of carburizing it is probably with a CP of at least 1.10% in order to get the reported hardness and depth. They may not be telling you that they are also shot peening to improve fatigue life. As far as the 4340, the noted Brinell is on the low side for a gearing application. I would look into induction hardening of the teeth of your gear and then challenge the customer again.I'm surprised their carburized gear doesn't last FAR longer than yours. How does your fail--tooth wear? Shotpeening won't help there. You need surface hardness. You might try low-temp. nitriding the 4340, which might outlast their gear. Gold is for the mistress - silver for the maid Copper for the craftsman cunning in his trade. "Good!" said the Baron, sitting in his hall But iron - cold iron is the master of them all. Rudyard KiplingThis thread reminds me of a problem a maintenance department had with a pinion from a hand hoist at a previous job. It seems this particular pinion failed after many years of service and the maintenance department was making new ones, which were lasting only a few weeks. They were using a 0.40-0.50 carbon Cr-Mo steel at 300-350 BHN. I suggested to the maintenance supervisor that he flame/induction harden the teeth (which were what was failing). He argued that it wasn't wear, that the teeth were breaking off and making them harder wasn't the answer. I told him that fatigue was probably the base problem and that the hardening operation would stop the fatigue. I was convincing enough to get him to try it. As far as I know, that pinion is still in service (although this was over 10 years ago, so it wouldn't surprise me if the entire hoist had been replaced). That maintenance supervisor was very surprised. The bad side is that he started coming to me with all of his problems after that... rpDown and dirty method for heat treating 4140 part - Metal ...Mar 25, 2012Heat treating A36 steelJul 13, 2006See more results

can i heat treat and temper ASTM A36 steel? Yahoo Answers

Nov 08, 2009 · A36 generally cannot be heat-treated, A36 can only be strengthened by cold-working, and even then, only up to about 60,000 psi. Heating the steel will only make it softer. The only real virtue of A36 is that it's easy to work with, it's easily cut and machined and it is very easy to weld.
