Fixture material
Fixture material
(OP)
I have been away from design for a few years.
What type of steel is suggested for a tool/fixture that will be placed into an oven for one hour? (couple hundred degrees)
I need steel that will not move or very little movement.

RE: Fixture material
How much movement (due to thermal expansion assumed) can be tolerated?
Answers to these two questions will define the maximum acceptable coefficient of thermal expansion that would be acceptable for you. Then pick a material with a lower number.
Depending on how little "very little movement" is, you may want a ceramic rather than metal.

5 x 12 x a x a couple hundred = 0.020

Sorry, I have been away from materials for a few years.
I'm looking for a steel that sees 250F for at least one hour, may be in contact with some corrosive materials.
I need it to last, has metal to metal contact, no rust...or very little.

It's a start up company and it is difficult to get info from others.
If you could please give me a range/type of materials, I can pick from the list.

For starters I would look at the appreciate size C/S mechanical tubing, available from any steel service center for the frame and if you need hard points I would use something like 17/4 SS machined to accommodate your component. The 17/4 would provide a nominal rust resistant hardened landing area. I would paint the CS with an appropriate paint for your environment, ours are painted with a high build inorganic/epoxy system.
There are some awfully good powder coating systems available at reasonable prices.
Interlakes has build quite number of bases and jigs for us especially if precision is involved.

I will stick with it.

Depending on your requirements an H1100 (4 hours @ 1100F, air cool)heat treatment works quite well in most cases.
