I think it is just a matter of funding research into high impact projects. You see a project like JF-17 and the amount of expertise that Pakistan has built around it and ponder as to why it is not taken as a blueprint for other projects as well.There are different types of marine steels for different uses for surface or subsurface ships.
The technologies are not shared esp for steel used in subs or minesweepers. For eg, PN Munsif Class that was put in service in the 90s uses a low magnetic steel used in it's hull construction. https://en.m.wikipedia.org/wiki/Tripartite-class_minehunter
IN which has been making ships and subs still can't produce their own minesweepers. They actually retired their last soviet era ships a few years ago.
I'm okay with us starting slow but have to keep on increasing our capability and can't go backwards. If Pakistan can produce low magnetic steel, it can be a supplier to a number of countries that have some semblance of ship building.
Same would of course help in lowering subs signature against MAD type of devices etc.
