high strength sheet metal 1

[mechengdude]

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

We start our by running stuff like this by HP alloys.

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.

AerMet 100 from Carpenter would be a possibility:

We use Easyform 400 or possibly 500 for stamped parts. The number is the yield strength in sensible units.

Depending on gauge, and width of the blank, I have seen alloy steels like 4130 in strip/coil form. In the annealed condition they wil have some formability, although I dont think you'd want to try drawing operations. Multiple cold working operations in a progressive type of die woudl probably not be to healthy (for the die) either.

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

I love materials science!

You might want to look at HSLA steels for our application. These alloys may allow you to do the forming with the as is material requiring no other treatment.

Some of descriptions of the different materials.

Yes I think that is a BHP Billiton HSLA. Well, now I look for it I can't find it, maybe I've got the wrong name.

Greglocock,

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

[GregLocock]

That's the same stuff.

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

Have you ever tried 6262 material?
Its good machinability with high-strength.
Corrosion resistance and finishing characteristics are better than 2011, 2017, 2024,and equal to 6061.

mechengdude- I guess you are going to have to tell us what sort of strength you really need, we have several options in this thread. In order of strength:

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

Look at ASTM A-1011

 

[GMIracing]

If in the EU, I recommend EN 10149-2 (Hot Rolled) or EN 10268 (Cold Reduced)
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.
