Boring métalurgic details
" 50-kilogram (110 lb) mild steel. Conversely, the upper plating, specifically the deck, ammunition lobbies, gun shields, bridge, deckhouses and the lower part of the aft-funnel; were made from high-tensile, 60-kilogram (130 lb) bullet-proof "gunshield quality" (qualité masque) steel. This was a chrome-cobalt-molybdenum alloy that was used in warship armour and the French equivalent to Royal Navy, Ducol "

50 Kilogram and 60 Kilogram are technical term for refer to the quality of steel and specifically the ductility.

The French navy usued three grade of steel, the''50 Kg"  mild steel , the '60 Kg " who is an hight tensile steel  and the "80 kg " for the armor grade steel ( mostly the turrets of battleships  ).

Hight tensile steel, exactly like the Ducol ( interesting to note ) become popular during the interwar for save weight , it was typically usued on light armor  ( gun shield ) and bulkhead.

I recomand to use "mild steel " and "hight tensile steel "  and to note the similarity the Ducol ( it's a brand )  and the "bullet proof" issue ( it's interesting ).
