Often replaced stainless thick wall with DOM for High Pressure Hydraulics because of burst resisitance and cost (namely TuffDOM 620: Tensile 100,00, Yield 90,000). Thick wall DOM was harder to bend than same size
solid round stock. And DOM "IS" harder to machine then
solid A36. You need to work with the stuff to know the difference, so yes, I stand by my statement.
Please explain your common usage of the word solid, it is confusing.
eg. Thick wall DOM was harder to bend than same size solid round stock. Same size solid what? It makes a difference what the material is, see my point?
DOM steels can be many grades, low carbon and alloy. So the DOM used on these tubes could be anything from low carbon to your TuffDOM, you see where I am coming from and that is my argument in the first post, it all depends on the steel.
