high strength sheet metal
(OP)
Can anyone give any recommendations on a "high strength sheet metal"? To give a little more detail, I have used a variety of aluminum and steels in the past for bent sheet metal parts. They are all typically not brittle which is obviously why they are used for sheet metal (ie) no one wants a part to crack during the fabrication process. What I need now is something much stronger than the typical aluminum 5052-H32.
In the past I've used some ultra high strength materials like MP35N for machined parts to reach very high strengths but have never needed it for bent sheet metal. What I'm looking for now is the "MP35N of forming material". The material thickness is in the range of about .125". Cost is not a concern in this application. Any suggestions appreciated.
Thanks

Nice folks and really know specialty (HP stands for High Performance) metals.
They know the metals and the markets. Sometimes what we want is a year out and they are honest about that.
No connection, just a happy customer although Scott and Jerry did take me fishing once.

Greg- Are those trade names of HSLA Steels? Is there a corresponding SAE J4nn spec that applies?

I love materials science!

Could be that this is the material you had in mind?

It works out chepaer than mild steel if you are fatigue strength limited.

Its good machinability with high-strength.
Corrosion resistance and finishing characteristics are better than 2011, 2017, 2024,and equal to 6061.
RE: high strength sheet metal
MP35N -- Stainless -- Yield up to 290ksi, Tensile to 300ksi
4130 -- not stainless and can hit ~190ksi UTS.
HSLA Steels -- not stainless strength to ~100ksi? (SWAG)
Aluminium -- soft, corrosion resistant, low modulus strength to ~80ksi

RE: high strength sheet metal
If in NAFTA, I recommend ASTM A 1008 (HR), ASTM A 1011 (CR) or SAE J2340 (HR & CR)
They cover HSLA sheets of various TS levels. Formability is of course reduced with increased TS.
