Nasr's Sauber C34 car has been an early season hit and his best time of 1min 21.545 in 108 laps was enough to end Ferrari's dominance on the leaderboard from the opening couple of days.
However, technical problems persisted for McLaren and Red Bull as Alonso and Daniel Ricciardo were at the back of the grid both in time and laps completed.
Raikkonen took over from new teammate Sebastian Vettel in the SF15-T, but couldn't match the pace set by the German on the opening two days as he was 0.205sec behind Nasr in his 92 laps.
Mercedes continued to prioritise mileage over speed as Nico Rosberg racked up 151 laps to add to his world record 157 lap effort on day one.
Rosberg could even have managed more, but his W06 had to be towed back to the garage after stopping on the track midway.
McLaren looked to have put a disappointing opening couple of days during which Alonso and Jenson Button managed just six laps apiece behind them early in the day.
Alonso was able to log 32 laps yesterday morning, albeit 14 seconds off the pace set by Nasr. Yet, worse was to come as cooling pressure problem in the power unit prevented any running after lunch to once again leave them as the team with the least amount of mileage on the day.
