Default What is the steel in hydraulic pistons?

In article ,

Check Craigslist for a used Olympic barbell. The ends are 50mm and about
18" long. I have been cleaning out a house with an old gym and got rid of
several of them.



Now that I think about it, I have a specialty bar left over. It is about 3
feet long and seems to be stainless steel. It is a constant diameter,
probably 2" rather than 50mm. You can have it if you are near Cleveland.
