The 845 plate curves show about -51 volts grid bias for a plate to cathode voltage of 430 and 62ma. (small red dot)There will be differences from tube to tube and the filament voltage will effect this as well.
If your filament voltage is low then the tube will not want to conduct as much and you will not need as much negative grid voltage (bias) to keep the plate current at 62ma.
