HELP FINDING A SUITABLE METEL FOR METHANOL SUBMERSION
HELP FINDING A SUITABLE METEL FOR METHANOL SUBMERSION
(OP)
We have an automotive fuel system part we need to machine that will be subject to 99% Methanol. We are open to nearly any metal as long as it has a high level of machinability and is not an exotic (expensive) material. We have considered 300 series stainless and a few Brasses. The OEM part we are replacing is brass but known for corroding over time.
Can someone point us in the right direction for a material selection that will machine nice, is relatively inexpensive, and will perform well in Methanol? We do not need 100% corrosion resistance but an improvement over the OE parts is a must.

We also will need to stay with metallic materials due to this being a metering valve.

The Outokumpu's Corrosion Handbook is listing all the austenitic stainless steels as suitable for methanol environment (100% @ 65 deg C - boiling point!), with less than 0.1 mm/year corrosion rate. In fact, that's equivalent to almost 0 mm corrosion allowance or using Outokumpu's words, 'corrosion proof'. You can also visit the Outokumpu website and order your own free famous Corrosion Handbook (there are quite a few other similar books on the internet from other sources).
