Titanium may be good to replace 4130, but expect to pay much more and
welding requires special consideration. 6AL-V4 has a 160,000 PSI.   Harry

I am in need of a robust, salt water resistant alloy for my seaplane landing
gear arms. I thought most titanium alloys had the compressive strength
around 70,000 psi. 160K is impressive.  What does the V4 indicate?

The shop next to me has just started doing titanium welding.  Inert gas has
to be applied to both sides of the weld I 'm told.
