What would be needed from LBL for infrastructure projects ?
Maybe out of ignorance in that sector the repairs on concrete pump impellers is all I can think of , or maybe turbine blades for the pumped hydro scheme .
I was thinking maybe they could get some work on the new submarines that will get built in Adelaide ie torpedo tubes probably need harder than standard steel liners , but that is probably years away , and bisalloy probably has that sown up
Mining machinery would have to be the area where they get the most work especially if the $US gets stronger making repairing rather than replacing even more viable .
what happened to the tungsten carbide hydraulic cylinder linings that were suppose to be a money earner ?
Maybe if this trade war heats up American steel mills will benefit which would be good for selling LBL hardened steel rollers to those mills
