Fatigue Properties of Duplex Stainless Steel

AI Thread Summary
A user is seeking a stress amplitude vs. cycles curve (S-N curve) for Duplex Stainless Steel SAF 2205, having unsuccessfully searched various resources, including the Atlas of Fatigue Curves. A suggestion was made to refer to a specific document from AvestaPolarit, which contains relevant data, albeit for seawater conditions. Additionally, contacting AvestaPolarit or AB Sandvik Steel directly was recommended for more precise information. The discussion emphasizes the difficulty in locating specific fatigue data for this material. Assistance in finding this information is highly sought after.

Hello All,

I'm hoping someone can assist me in locating a stress amplitude vs. cycles curve (S N curve) for a Duplex Stainless Steel. The particular material I'm using is SAF 2205.

I have been searching far and wide, including the Atlas of Fatigue Curves, but I have not been able to find such data.

Your assistance would be sincerely appreciated.
Regards,
Rodney

See page 7 - http://www.avestapolarit.com/upload/documents/technical/datasheets/AVPDuplex.pdf ,
but that's in seawater.

One may wish to contact AvestaPolarit and/or AB Sandvik Steel directly for such data.

Thread 'How could I make it so ferrofluid drops do not coalesce?'

Hello! I've been brainstorming on how to prevent a lot of ferrofluid droplets that are in the same container. This is for an art idea that I have (I absolutely love it when science and art come together) where I want it to look like a murmuration of starlings. Here's a link of what they look like: How could I make this happen? The only way I can think of to achieve the desired effect is to have varying droplet sizes of ferrofluid suspended in a clear viscous liquid. Im hoping for the...

Thread 'How do you fabricate microfluidic chips in your lab?'

Hello everyone! I am curious to learn how laboratories handle in-house chip manufacturing using soft lithography for microfluidics research. In the lab where I worked, only the mask for lithography was made by an external company, whereas the mold and chip fabrication were carried out by us. The process of making PDMS chips required around 30 min–1 h of manual work between prepolymer casting, punching/cutting, and plasma bonding. However, the total time required to make them was around 4...
