High Temperature spring material

High Temperature spring material

High Temperature spring material

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 ?

RE: High Temperature spring material

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.

RE: High Temperature spring material

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 ***

RE: High Temperature spring material


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


RE: High Temperature spring material

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

RE: High Temperature spring material

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.
