Machinability of BN free-machining steel in turning

International Journal of Machine Tools and Manufacture, 2007
Abstract In the past few years, extensive researches have been done to improve the machinability of work materials in order to increase productivity and reduce the effect on the environment. To satisfy these demands, various free-machining steels have been researched and developed.

Structure—Property Relations in Free Machining Steels

Journal of Engineering for Industry, 1980
Variations in machining characteristics accompany differences in microstructure in resulfurized free machining steels. In this paper a relation between machining properties of this class of steels and their principal microstructural features has been derived.

Corrosion of Resulfurized Free-Machining Stainless Steels

Corrosion, 1970
The influence of manganese (0.3 to 2.4%), sulfur (0.01 to 0.4%), sulfide composition, and heat treatment on the corrosion resistance of 13% chromium, 17% chromium and 18% chromium-9% nickel steels has been investigated. Corrosion in acid solutions, high humidity, and salt spray is dependent upon sulfide composition which in turn is determined by the ...

High-temperature deformation characteristics of free-machining steels

Metals Technology, 1982
AbstractThe high-temperature deformation of three as-cast free-machining steels with different lead contents and Mn : S ratios has been studied by torsion testing at temperatures in the range 900°-1 150°C and at constant strain rates in the range 6·9 x 10−3–5·3 S−l.

Free Machining Steel: I—Tool-Life Characteristics of Resulfurized Steel

Journal of Engineering for Industry, 1961
Tool-wear and tool-life characteristics of a series of five steels of different sulfur content are presented for different values of cutting speed, feed, cutting fluid, and cold work. While the presence of manganese sulfide in steel is generally found to extend tool life, certain combinations of speed and feed yield result that indicate the reverse ...

Free Machining Steel: II—Tool-Life Characteristics of Leaded Steel

Journal of Engineering for Industry, 1961
High-speed steel tool life results are presented and discussed for a leaded and nonleaded steel from the same heat. Variables investigated include cutting speed, feed, cutting fluid, and cold work.
