Previously, the materials used for converter furnace tubes included HK40 and HP; by the 1980s, microalloyed materials were employed. I’m not sure what materials are being used nowadays; I would appreciate expert advice.

Currently, technologies with a low water-to-carbon ratio and high furnace temperatures are used, and the furnace tube materials are generally alloys of Cr25%Ni35% along with NbTi and other elements
