    Database of Charpy Data - Where to find

    blacksmith37 and EdStainless, I don't have the printed version I do have access to the online version. Volume 1 is Properties and Selection: Irons, Steels, and High-Performance Alloys. Is this what your seeing? Vol 3 is Alloy Phase Diagrams.

    Database of Charpy Data - Where to find

    I am sure this exists and don't mind paying for it. I am looking for a comparison of Charpy test results of different steels (4130,4330,9310,3312,4340,300M) at different hardnesses. I have searched through ASM International and found nothing.

    Help with heat treating 52100

    So the material would come in as rolled. So it could annealed..... The part is hung vertically when heat treated in oil at 160°. Have heard a few comments about having it stress relived, the recommended process was, Rough Turn with .125" of dimensions Stress Relieve 2nd Operation rough...

    Forging 1045 Cold Rolled

    We currently produce a machined wrought connecting bar that is composed of 1045 Cold Rolled Steel, this material has a YS of 85ksi and a UTS if 115ksi. We are exploring forging this piece but are concerned about using 1045 Cold Rolled bar. As the heating to 2300°F due to forging may effect the...

    A514 from one supplier to another = problems!

    More info from each of the suppliers. - As it turns out the machining was changed in an effort to reduce cycle time. This definitly could be causing this problem. - The one vendor that supplier the "good" plates plasma cut them. Waiting on the other vendor. Swall, the part is to be flat...

    A514 from one supplier to another = problems!

    They will not be annealed or stress relieved as ASTM A514 only calls for Q&T. None of the mill certs from each company show any post processing other then the temper. The disc are cut from 3/4" plate. Would flame cut or plasma cut change the stresses?

    A514 from one supplier to another = problems!

    We have ran into an interesting problem in regards to A514 material. The pieces are 13.5" diameter discs of 3/4" thickness, the are machined down to a slim profile of about .188". The finished piece almost looks like a bowl. Anyhow from one supplier we get very little movement after...

    Help with heat treating 52100

    I need some help in regards to heat treating a camshaft of 52100. - Currently we start with a round 2" billet, its roughly 6.5" long. - Its rough machined, down to an effective diameter of about 1.25", with an eccentric lobe in the center (hence the 2" bar material). 0.020" is left on all...

    Solidworks Subscription/Maintenance & Simulation

    Yes throughout the day 4 of the licenses are being used by 5 people. 2012 SW has one feature that we would use all the time so I am wanting to upgrade. The advice to skip maintenace packages to every other year is what I think I will be doing, as we skipped over 2011 altogether.

    Solidworks Subscription/Maintenance & Simulation

    kellnerp, I have voice my displeasure with reseller about feeling locked in with my simulation. I will look at 3rd party sources. Thanks

    Solidworks Subscription/Maintenance & Simulation

    We are currently using Solidworks in a networked license arrangement (5 seats). Our maintence contract has come up for renewel. I am looking at around $14,000. Are their any legit :) methods of reducing this fee? 1 seat of SW Pro 2 seats of SW Pre 1 seat of SW Pre/Sim 1 Seat of Flow...

    Help with spec for new Cad Station

    I agree with kellnerp. Lowest end quadro (depending on your assembly size and if your doing rendering) and fastest processor available. The processor is the key.

    Heat Treat Standards on print

    Salmon2, a couple of the numbers I used were to illustrate what is typically on the print. The numbers may not be correct, I was more focused on how to explain or call them out on the print correctly. Thanks for all the feedback though.

    Heat Treat Standards on print

    What we currently have done is for example, 1045 Q&T Min 75 ksi Yeild Min 100 ksi tensile Min Elongation 15% Hardness Approx. HRC30 (MIL-H-6875) I would think this is enough, but I would think I would need to mentioned to descale the part as well. The challenge comes in when case hardening, I...
