Elon Musk tweeted that the Super Heavy booster grid fins will be made of welded steel instead of titanium.
Btw, regarding Super Heavy: given that Falcon 9 grid fins are *already* the largest single piece titanium casting ever (humans for scale in pic below) … how on Earth are you going to manufacture the grid fins needed for Super Heavy!?

Elon Musk in his Starship presentation had said that the Mark 3 version of Starship would be the version that goes to orbit. Recent video of the construction shows that new single seam rings are being made. Those would appear to be the first rings for a Mark 3 Starship.
