But they were pinned back in the final session and had to scrap it out for the points.
Sadly, with Cardiff Devils winning 8-0, they didn’t put a dent in the Welsh club’s lead at the top of the table.
Saturday’s 3-0 middle period made up for a sterile first session in which a five minute power play - given when Alex Nikiforuk boarded Markus Nilsson - came and went without troubling goalie Miika Wiikman.
Steelers went into the game one point ahead of Belfast Giants, in second place, six points behind leaders and title favourites Cardiff Devils.
And they were in for an explosive start when Geoff Walker fought with Jeff Brown centre ice - Brown lasting longer on his feet.
Mike Ratchuk, guilty of a couple of give-aways, was unfortunate with one darting run into the Notts slot.
But Panthers’ five-minute kill seemed to take the sting out of Steelers’ offence.
A speculative left wing shot from Mathieu Roy opened the scoring at 20;31.
His firm drive surprised the less-than-nimble Wiikman.
And Roy too - judging by his expression.
John Armstrong’s shot four minutes later doubled the advantage, Jonathan Phillips having deflecting the effort home.
And it was 3-0 when Ben O’Connor’s prompting set up Walker.
Nottingham’s Stephen Schultz and Brown both wasted chances on the Power Play to ensure a middle period clean sheet.
As much as Sheffield dominated that period, Nottingham dominated the next.
Robert Lachowicz ghosted past Davey Phillips to score at 42;39.
And just 47 seconds later Sheffield’s defence and first line were outworked - David Clarke scoring from the slot.
Panthers then had four clean chances to level.
There was a brief respite when Guillaume Desbiens broke clear, but Jindrich Pacl, who had taken over in goal at the second interval, saved brilliantly.
Captain Phillips scored an empty netter to ensure maximum points from an eventful game.
Coach Paul Thompson admitted Panthers had a dominating few minutes, but was pleased how his team closed the game down. “It was pretty easy for two periods...we just have to keep it rolling.”
* Steelers’ owner Tony Smith has swiftly responded to criticism from some Sheffield ice hockey fans for taking part in the fans’ 50-50 lottery draw.
Last Wednesday, after the game with Edinburgh Capitals, he won the jackpot...but immediately put the cash into a roll-over for tonight.
In the programme for tonight’s game with Nottingham Panthers, Smith wrote: “My inbox was full because of my 50-50 win. Some great comments which really mean a lot but as expected some nasty ones from people who don’t know me and have never met me.
“So to the ones who feel Steelers’ staff should never buy tickets I say you’re wrong.
“What you’re actually doing is throwing doubt on the credibility of not only the Steelers draw but the whole organisation.
“Steelers pride ourselves on how the draw is conducted and how transparent it is, so please stick to your day jobs be it web design, driving lorries or accountancy - it smacks of sour grapes to me.”
*Former Steelers’ coach Alex Dampier has been allowed home to Canada after bone marrow transplant and other treatment in Cleveland, America.
