Where can I purchase 17-4PH in the H1150 condition?
Where can I purchase 17-4PH in the H1150 condition?
(OP)
Hi,
Does anyone have a source for this? I am located in western Canada and everybody seems to only supply it in condition A.
Thanks in advance

I expect the reason is that there are many possible conditions and the suppliers just keep it in the condition the mill supplies.

I'd almost always rather machine it somewhat hardened over the "A" condition. Easier on tooling, cuts consistently and much better, and you don't have to do any post-heat-treat machining for precise surfaces that may move out of tolerance from heat treating. H1150 puts it in the high 20s to mid 30s HRC which it beautiful to machine.
We typically either get it "A" or a heat treated state I cannot recall. We typically source steels from Alro or EMJ.
I believe you can get H1150 from EMJ if they are in your area. ( http://www.emjmetals.com/ )

Honestly, we do hard-machining of steels up to about 58 HRC depending on material without having to switch to ceramic tooling.

To get an idea of heat treat costs, a few weeks back I purchased 24' of 3/8" diameter 17-4PH (AMS 5643) cond A cold finished bar and then had it heat treated to cond H1025. The material cost was $88 including shipping. My local aerospace heat treat vendor charged $130 for the lot, including paperwork. That works out to $23.90/lb total for a relatively small amount of material. The material was delivered to my house within 2 days after ordering, and the heat treater had the material ready for pick-up within 3 days after I dropped it off.
Here's a tip. If you are making multiple parts from a long length of bar stock, before sending the raw material to the heat treater it is best to cut the bar stock into pieces just long enough to machine a part from. Heat treaters typically have many different sizes of furnaces, and they usually prefer using small ones since they are cheaper to operate. Sending cut pieces of material to the heat treater will reduce your lot charge, and will ensure your job is not delayed waiting for a larger furnace to become available.
