Austenitic Manganese Steels Total Materia Article

An overall reduction in grain size lowers the susceptibility of the steel to hot tearing. Sulfur. The sulfur content in manganese steels seldom influences its properties, because the scavenging effect of manganese operates to eliminate sulfur by fixing it in the form of innocuous, rounded, sulfide inclusions.

Niobium Metal. Niobium is ductile, malleable metal, highly resistant to corrosion, and not naturally occuring in the free state. Niobium metal is produced by the aluminothermic reduction of the niobium oxide followed by electron beam refining.
