Continuously Cast Special Steels and Their Applications to Automobiles

Extremely high quality is required for special steels employed for automobile components. Therefore careful consideration was given to maintain high purity, homogeneity and sufficient reduction ratio prior to introducing a continuous casting machine.

With this machine it became possible not only to produce steels with outstanding cold forgeability and fatigue strength but also to produce steels with highly homogeneous hardenability, machinability and distortion.

Furthermore, estimation tests were carried out for automobile components and it was confirmed that continuous cast steels were performing as well as those of ingot cast steels.
