Steel

Steel

(OP)
I am designing a custom press using a 25 ton hydraulic cylinder, and I was curious if anyone had suggestions in types of steel that are relatively cheap with a strong enough yield strength to handle 50000lb of force. The engineer I was working with wanted to use 4130 normalized steel but it seems to be pretty pricey.

RE: Steel

Not nearly enough info provided.

Bad geometry can easily overcome high end material mechanical properties.

Unless you have severe weight or space constraints I'd expect properly sized commercial steel structural shapes could be selected that work just fine.

I expect commercial presses are made of readily available commercial steel structural shapes

RE: Steel

Are you looking for rolled steel structural sections? If in the US, you might be looking at the AISC sections; they come in rolled sections and plate. They are quite inexpensive.

RE: Steel

I built a 10-ton press using readily available rolled shapes (Standard channels, A36 material). As Tmoose noted, the geometry will control the stress levels.

(OP)
Thank you all for the pointers.

RE: Steel

Detail appears to be in inch units. Any reason why you are limited to 1/2" thick plates? If not why the high strength steel? Also, assuming this act similar to a coat hanger, I'd look at the possibility of bucking sideways. It appears too skinny at thickness shown.

RE: Steel

If deflection is a controlling factor, the higher strength steels wouldn't gain you anything.
If weldability or fatigue are concerns, higher strength material may not be advantageous.

RE: Steel

Most log splitters are in this range or heavier and, as far as I can tell, many use standard AISC rolled shapes
