The SpaceX Super Heavy Starship (SHS) will switch from 301 steel alloy to 304L steel alloy for some parts and then a new custom steel alloy.
The 304L steel is a lower carbon version and it will reduce welding issues.
Marcus House indicates that there are a lot of Raptor engines coming through.
The third prototype version of the Starship (SN3) is rapidly being stacked.
Some parts will use 304L, as it has higher toughness at cryo temps. Will move to internally developed alloys probably end of year.

Lot of Raptors coming through! Now operating both horizontal & vertical firing stands in McGregor.

Pretty close. Design is evolving rapidly. Would be great to flatten domes, embed engines & add ~1.5 barrel sections of propellant for same total length. Also, current legs are a bit too small.
