Study of machinability on drilling austenite stainless steel 316 L1 by solid cabide tool

Austenite stainless steel is one of the most important engineering materials with wide variety of applications. Superior resistances to corrosion and compatibility in high temperature and high vacuum have particularly made it an attractive choice. However, the machinability of austenitic stainless s...
