Investigating the Machinabili-ty of AISI 420 Stainless Steel Using Factorial Design[J].Materials and Manufacturing Processes 2008,23(3-4).El-Tamimi, A.M.; El-Hossainy, T.M. Investigating the machinability of AISI 420 stainless steel using factorial design. Materials & Manufacturing Processes ...
Machinability depends on the physical properties and the cutting conditions of the material. Machinability can be expressed as a percentage or a normalized value. The American Iron and Steel Institute (AISI) has determined AISI No. 1112 carbon steel a machinability rating of 100%. Machinability of...
Thus, if another steel X has a rating of 70% of B1112, you adjust the cutting speed to 70% to achieve a 1-hour tool life. Each metal association (e.g. the Copper Metal Working Association) defines these comparative ratings for the various alloys for which they have authority as the ...

But lately focus of researchers shifted towards the concepts of sub-zero treatments. In the present investigation, PVD coated and uncoated carbide inserts were subjected to deep cryogenic treatment(-1960C) in order to investigate the machinability of stainless steel. Micro-structural study, elemental ...
The impeller material FV520B-hardened stainless steel is a typical difficult-to-machine material. During the cutting process, the force and thermal load ar
ferritic stainless steel and martensitischer stainless steel with excellent machinability A ferritic or martensitic stainless steel has the structure that Cu-enriched particles with concentration of C not less than 0.1 mass % or concentration of......
1. A method of improving the machinability and mechanical properties of a steel which consists essentially of adding to the molten steel in the ladle a sodium oxysulphide and adding at least one element selected from the group consisting of selenium, tellurium and bismuth to the molten steel in...
