Use of zirconium in methanol

[materialsunshine]

Does anyone know if there will be problems related to the use zirkonium in a valve. The valve will normally handle seawater, but the media can occationally, for short periods, be pure methanol. The temperature is about 60C.

Zirconium seems like an awful expensive choice for methanol, why not high-moly stainless steels or non-metallics ?

Zirconium is unaffected by methanol:

Please see FAQ731-376 for tips on how to make the best use of Eng-Tips Fora.

Thank you for the help. The material is choisen because there is NO toleranse for corrosion for this part. The media is not normally methanol, but a mix of produced water and reservoir gasses. At this temperature, this inviroment is devastating for many materials. But I will check up the suggested materials,joeswoes, and see if they can "do the job".
