Elevated Properties of Steel and Stainless Steel
Elevated Properties of Steel and Stainless Steel
(OP)
Has anyone run across published physical property data for steel and/or stainless steel at high evevated temperatures? We're attempting to input steel property data into a FEA analysis for a muffler. Steel temperatures run in the 1000F neighborhood in these applications.

First, I think that I've found enough information to satisfy my immediate needs. So thiank you.
I had hoped to find an authoritavie resource or study that specifically address high temperature strength properties of sheetmetal type materials. Often, published high temperature data is for structural steels used in buildings are are specifically related to strength requirememts during fires. There is some data out there on specific high temperature use steels, or stainless but much of that info on the internet has been generalized, published by company marketing departments, or else not specific to steel types that are in everyday use for small engine exhaust systems.
To answer the question about types of steel, we use 304, 409, 430, stainless materials and also aluminized CRS materials of which base steel is probably of a commercial steel (?) type.

It is the best source. Most data is older but it has all be reviewed.
I'll get the ISBN when I get home.

Be really cool to know for exactly what grades you need data . . . there is no such thing (pretty much) as 304, most is dual certified 304L/304 adjusted to meeet the 304 min yield requirements. Or else dual certified 304/304H, carbon level to meet both specs.
I put a lot of effort into getting together accurate data for Rolled Alloys data sheets before I retired. There is a lot of data available. I also have had some doubts about marketing-published data but managed to sort it out. The Swedes tend to be honest.
And after looking up all the fine tensile & modulus properties I must tell you that 80-90% of all high temperature failures I investigated over three decades were because the designer, or the installer, failed to recognize that metals will expand with heat. One may permit the metal to expand freely, or else watch it bend, crack or tear. Data is nice but recognizing, and allowing for, thermal expansion is make or break. In my experience it is nearly impossible to convince a degreed engineer of this. Small farmers and Skilled Tradesmen do tend to understand.
