The all-rounder's brutal 50, which included five sixes, came off just 15 deliveries as the Sixers posted 5-177 at Blundstone Arena on Sunday night.
Christian came to the crease with the Sixers 3-58 at the start of the 12th over after they struggled early on a nippy pitch and didn't stop swinging until he fell one ball after notching his milestone.
Adelaide's chase got off to a quick start courtesy of Salt and Jake Weatherald, who paired up for 52 inside five overs to gain the Bash Boost Point, but Christian broke the stand and finished with 1-25 as the Strikers ended on 7-139.
Seamer Dan Worrall had the ball talking early for the Strikers after they elected to field, taking 2-12 off four straight overs that included 18 dot balls.
For the second time in as many matches, Adelaide opted to use the X-Factor Substitution, bringing Liam Scott in for his maiden appearance in blue. Under new rules this summer, teams can replace a member of their starting XI at the 10-over mark provided they haven't batted or bowled more than one over.
While he was unable to get the job complete with the bat, a positive for the Strikers was Jon Wells getting plenty of time in the middle. He finished unbeaten on 36 in a performance that Adelaide will be hoping is a sign of things to come from their top run-scorer last season.
The Strikers now turn their attention to a fixture against Brisbane Heat on Wednesday evening at the Gabba, with first ball scheduled for 6.45pm ACDT.
