Titanium or Stainless steel?
Hi all,
I have a question about material choice for a bleeding nipple going into aluminum. The existing one (zinced steel) is fused in the aluminum hole. Removing it strips the aluminum thread.
The choice of material I have is 316 grade stainless steel or grade 5 Titanium.
Given that the torque on the bleeder is only 20Nm the only concern is corrosion resistance and especially galvanic corrosion from the road salt.
Which one would you chose for this application?
Should I be worried about galling with stainless steel?
Thanks!
