Hello,

Looking for best material for a check valve for cryogenic application on LNG at -196°C

Is ASTM A351 CF3 better than A351 CF3M ?

Thank you.
 
Normally 304L type stainless steel would be specified.
 
No corrosion issues, so no reason to up the alloy content CF3 should work fine.
It should be solution annealed, some casting specs don't require this.
