Object description

Space Age expansion exclusive feature.

Steel plate productivity reduces the cost of crafting steel plate by adding productivity to the craft. This reduction affects the steel obtained both from smelting with furnaces or casting with the foundry.

Note that the 300% productivity limit does apply to this technology. It can be researched past level 30, but it will have no practical effect.

Thresholds

The table below shows the total productivity bonus at key research levels for Steel plate productivity (research), for each machine and module configuration. Productivity is capped at 300%; cells shown in bold indicate that the configuration has reached the cap at that level and will not improve further with additional research.
