High Temperature spring material

[EngineerRed]

I'm looking for a spring material (preferably alloy steel) that could withstand operations in temperatures as high as 1200 deg F . Can anyone suggest a material please ?

I don't think you're going to find an alloy steel that meets that requirement. You'll need a nickel or tungsten alloy. ASTM-A286 would be the lowest spec material that approaches that requirement.

I think Inconel X750 would be your best choice (1300 F max.).


*** Per ISO-4126, the generic term
'Safety Valve' is used regardless of application or design ***

*** 'Pressure-relief Valve' is the equivalent ASME/API term ***

Ceramic?

EngineerRed,

Titanium is a good spring material. What is its maximum high strength temperature?

Depends on how hard it needs to be . As answered Inconel X, 718, MP 35 N, you are going to need to talk to a vendor. Possibly Standard Pressed Steel , Jenkinstown PA ( if they are still in business). Titanium is a non-starter

If you want to operate at 1200F you need to be looking at materials where the aging or temper temperatures are above 1400F.
These will all be Ni alloys.
