Abstract
PURPOSE: To provide the titled free-cutting steel by a method wherein a proper amount of Te is added according to the quantity of S which is used to give the free-cutting properties to a stainless steel or heat-resistant steel, and the form of sulfide-based interposing material in the steel is improved by adjusting the quantity of O.
CONSTITUTION: The titled stainless steel or heat-resistant steel consists of C: 2.0% or less, Si: 5.0% or less, Mn: 20.0% or less, Cr: 7.0W30.0%, S: 0.4% or less, Te: 0.5% or less, O: 0.015% or less, and the remaining Fe. The restrictions in the steel are: sulfide size with the major and minor axis ratio of less than 10 for 80% or more of relatively large size sulfide having major axes more than 2μ; Te/S weight ratio of more than 0.04; and O content of 0.15% or less. This provided the free-cutting steel excellent in cold forging propeties, useful in such fields as requiring high corrosion resistant stainless steel or high-temperature strength heat-resistant steel, without losing such properties.
