Thanks boo1 for the reply - I concur with your evaluation. Unfortunately those who wrote ASME B30.20 and if I'm not mistaken ANSI/AWS D14.1 did not include a vast array of building materials that may be suitable for the applications at hand. Using a low to medium carbon steel with a SF=3 shows...
Thank you davefitz for the reply. It is interesting to see how this is handled in the pressure vessel standard. Do you have recommendation on how to correlate this to the ASME B30.20 standard (Below-the-Hook Lifting Devices)? The only design guideline that I can find presented here is: "A...
I am trying to determine how the industry handles fatigue when designing to a pre-determined safety factor. If I want to design to a SF=3, it would seem purtinent to ensure this safety factor exists over the full life of the system. In order to determine this, you would need to know that the...
Thanks for the reply TVP! I found the carpenterdirect.com (cartech.com) about the same time as I got the e-mail. To this point, this website has been the most comprehensive source that I've found. I'll look into the other web sites as well.
Thanks for the help, I think I've found enough...
For the application, the hardness is not a characteristic that I care much about. In general it comes with the territory of the high strengths and consequently often makes the machining a slower process.
Do these alloys result in a "case hardened" form after heat treating? If this...
Thanks Jimbo51 for the reply. I've been looking at the 15-5 (H900), the 17-4 (H900) and the 440 series stainless. One ASM chart shows the 440 series to be easier to machine than the precipitation hardened options, however this is in the non-heat treated state for all of them. I do not know...
We are wanting to fabricate rotation shafts out of high strength stainless. Due to lead times of our product, it would be best to machine the shafts in the high strength condition rather than heat treating afterwards. Does anyone have a recommendation on an alloy that would meet the following...
