Spring material in 96% sulfuric
Spring material in 96% sulfuric
(OP)
What type of spring material would be recommended for 96% sulfuric, ambient temperature. This is a pipeline application so it probably has no entrained air.
We currently stock Inconel X750 springs. But I am afraid that these will not last very long. Is that true in your experience?

There are grades oof SS like 302L and 316L that have very low amount of carbon, you may want to try these.
X750 has 0.08 max %C as does 302 and 316. The "L" versions have 0.03% max carbon, the 316L will perform better than the 302L. You may also consider using HASTELLOY® D-205TM alloy, which is designed specifically for high sulfuric acid concentrations and does come in wire.
