Which risk increases when attempting to scale up production of crucible steel in the 18th century?

💡 Explanation

When crucible steel production is scaled up, increased ingot size promotes carbon segregation because diffusion distances increase during solidification, leading to uneven carbon distribution. Therefore, carbon segregation increases, rather than silicon reduction, nitrogen decrease or faster cooling rates which are affected by different process parameters.
