Boring métalurgic details

[edit]

" 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 , the50 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 ) .
