Heat Treatable Structural Steel Tubing Needed
Heat Treatable Structural Steel Tubing Needed
(OP)
Hello!
I'm working on a design that depends on the availability of rectangular steel tubing in 3" x 5" and 3" x 10" sizes, both 3/8" wall thickness. My design calls for a yield strength of about 130 ksi, and is weight sensitive, so throwing more mild steel at it doesn't make sense. We'd rather heat treat it than use more material.
Are there any structural steel grades, welded or seamless, that have a composition comparable to a 4000 series steel? For that matter, is there a source for 4000 series (4130, 4140, etc.) steel in this structural shape?
Thanks,
-Rodney Sparks

Contact a domestic structural tube manufacture to be sure.

However, I want to heat treat the welded assembly, so I don't necessarily need tubing that is already quenched and tempered. Is there a commonly available steel under a different spec than A514 that has a similar composition that I could quench and temper after welding in order to arrive at >=100 ksi?

Here are two suppliers of 4130 rect tubing. We used this a lot in building machine frames.

If you can use 70,000 min yield you might take a look here.
