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.
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.
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...
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...
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...
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?
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...
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...
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.
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...
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.
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.
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...
When creating manufactuering prints is their a standard on how to specificy the strenght the of the material or Heat treat procedure?
For example, I have specifcied a print for a forged valve. Can I just specify the Yield Strength, Tensile Strength and Elongation. Or is there a standard I...
We had a lab analyzed some unknown ball joint material, and the results were rather puzzling.
The lab unidentified the material as 8640, but with .2% copper. Could this be a custom grade of material specifically for increase wear resistance?
I was curious if someone can direct me to a source to help me estimate the amount of deflection from a rubber cylinder suspension bushing.
The load would be radial towards one side of the bushing. And with a given load I am looking to determine the deflection of the elastomer.
Thanks in advance.
I was curious if someone can direct me in the right direction. I am looking to predict the amount of compression/displacement of automotive cylindrical rubber bushing versus the load applied. The load of course would be applied as a radial force from the center sleeve towards the outside of...
