Continuous Casting of High-Alloy Steels

A continuous casting process for high-alloy steels such as 13% Mn steel, 9% Ni steel, and stainless steels (AISI 631, AISI 310S) has been developed at Chiba Works of Kawasaki Steel Corp. Tensile testing at elevated temperatures and microscopic examination of the fractured surface of the corresponding steel specimen have shown that the high crack sensitivity of these grades is due to segregation and/or precipitation of sulfur and phosphorus at γ-grain boundaries, and for 9% Ni steel, additional large thermal expansion at γ/α transformation.
