Chrome moly is somewhat stronger than the old 1025 steel that was usedwhen the Piet was designed, but the wear factor shouldn't be a problem. How much stronger depends on the temper or heat treat. Fully tempered4130 is four times stronger than similiar 1025, but the rudder bar cutfrom 4130 isn't tempered. I don't know why chrome moly or 4130 steel wasspecified for that. Didn't really think about it as we used 4130 steelthroughout. The weight difference would be negligible.John Langston writes:>I asked this one before but didnt get any answers>yet.
