The Titanic? The best thing they could do is use the right quality steel.
Cees,
I believe the theory is that the steel (plates) were OK but that the wrought iron (rivets) were of dubious quality. ( "Best No3" instead of "Best Best" )

The chain is no stronger than its weakest link!
Edit, did change the message because wrought iron is not cast / crude iron !
Read the story, the amount of slag as they found is depending of the cast iron of a blast furnace,'
Did work a few years at these furnaces (1924/1926 built!) and the quality of the left one Hoogoven 2, was good enough to make furnaces without any treatment of the crude iron
In the eary period the iron was sold as "bricks" to other factories.
The slag is separated from the iron directly after it leaves the furnace when iron and slag are still liquid, by difference in weight/mass.
In the Neterlands we call the orion/slag separator foxhole (vossehol). It all has to do with animals when we are talking about the Taurus and quality insurance, so still "on topic".
