Comparison of 440C with SS 321 for valves for steam service




Dear Sirs,
We are manufacturing Control valves and most of our valves are used in High Temperature Steam applications with temperature more than 450°C.

We use 440C as the trim/wetted parts for these valves. Recently we had observed that 440C is not suitable for high temperature steam applications and came up with an idea of using SS 321 or SS 410 Nitrided.

Can anyone suggest or comment whether the above material (SS 321 or SS 410 Nitrided) shall be a better solution for SS 440C (steam application)

Regards
