Under extrusion issue with new steel nozzle

Today I switched out my brass nozzle for a hardened steel one so I could print some more abrasive filaments.

I noticed that my prints began to de-laminate really easily after this upgrade. I increased my temps and that seamed to fix the issue… Is that normal? Is steel just less thermally conductive and thus needing a higher temperature?

The picture is just my two nozzles side by side
